Using Lab mode in Photoshop to add Saturation to your Digital Image Management & Retouching by Matt Anderson

Friday, March 19, 2010 by Matt Anderson
Todays tip will involve using Lab color space in Adobe's Photoshop CS4. We'll make a curves adjustment layer, tweak the a / b channels, adjust the layer opacity, and BAM! Your photo just got more color than a new 64 pack of Crayola's ! Prepress color management and color manipulation done fast.

Step one, open your image and under "Edit" menu, use the Convert to Profile command, and choose Lab.

Step Two go to Layer, New Adjustment Layer, Curves

Next Select the b channel, click on the curve (straight line) and put a point right at 50,50

Now take the endpoint shown below in the a channel, and drag it over to a point just to the left side of the histogram. In this particular image, the data starts around the 0,30 point.

Now take the endpoint shown below in the b channel, and drag it over to a point just to the left side of the histogram. In this particular image, the data starts around the 0,30 point.

Our final step is to adjust the layer opacity. The curve layer adjustment at 100% is a bit too saturated. I'm going to set the opacity to 60% as you can see below. This produces a nice looking colorful image, which should standout from the rest of your digital - image assets. This simple color correction technique takes less then one minute, and you can easily automate the process for a group of photos!

*Tip for advanced users. If you select the midpoints we anchored (50,50), use the arrow keys to subtley offest the points position. In doing this you can add / remove color casts to images. Use the a channel for red / green, b channel for blue / yellow. DAM! Color Retouching isn't that difficult after all.
 

It's not easy being 48L* -58a* 28b* (green).

Happy St. Patrick's Day!

On this St. Patrick's day, I thought I would pause to give props to the cool neural sensation we refer to as GREEN. This is "The Color Space", after all. Did you think I was going to discuss waffle makers here? No, for that you will have to see my blog called, "The Small Home Appliance Space".

As the list at the top of this post indicates, there are so many ways to convey the color green. It doesn't matter if you are a color scientist, color management geek, painter, photographer, school lunch lady, or St. Patrick's Day reveler, green has different meanings for everybody.

      
 
Quick Quiz: The image above is a) PMS 356C  b) 59R 138G 73B  c) GREEN, you idiot!  d) The Libyan flag  e) All of the above.... The answer of course is "e". Duh. Anytime you are given a choice of "all of the above", take it. This thought process never steered me wrong on multiple guess quizzes at John Marshall Senior High School. And I don't know if there is any truth to the rumor that the guy who designed the logo on the Cleveland Browns football helmets also designed the Libyan flag. 


"The color green is everywhere in nature, satisfying our spirits and filling us with neutrality and peace. Green comes alive in clover fields, rolling hills, and the leaves of a tall aspen forest. Easy on the eyes and naturally calming, green symbolizes life, harmony and wealth. Soothing as green tea, or invigorating as fresh mint, green will create a restful environment and promote well-being in any home... "

No, I didn't write that last paragraph, thank you very much. It was written by some copywriter in the marketing department of the Pittsburgh Paint company. They want you to buy some green paint to put on your bathroom walls because it's better than that dull taupe color you have in there right now. What are you thinking? That Taupe doesn't even come close to matching the new soap dispenser and tooth brush caddy you bought at Bed, Bath and Beyond last month...

Green is the color of nature, trees and grass.
Green is the color of spring and new life.
Green is the color of Kermit the Frog who often crooned about the difficulty of being green.
Green is the color of money and greed.
Green is the color of envy and jealousy.
Green is the name of the room that Lady Ga Ga waits in before she comes out on Leno.
Green is the color of ecology and conservation.
Green is also the color of those canvas bags at the grocery store that the Prius drivers want me to use instead of paper or plastic. Who needs all that canvas in the landfills? That seems wasteful. I'm sticking with plastic.
Green is the color of youth.
Green is the color we say someone is if they are new to something.
Green is the color of the Libyan flag. That's it. Just green. Really.
Green is the color of the jacket that Tiger left in the hotel room.
Green Day is a good band.
Green Bay Packers are a good football team.
Green is one of the colors of Christmas.



As my friend Kermit the Frog sings, it's not easy being green. So next time you find yourself 89C 10M 98Y 10K with envy, pour a tall frosty glass of 59R 138G 73B beer or a nice cup of 3b8a49 tea, and relax in the naturally calming PMS 356C room. 






RGB Workflows- Better Late Than Ever

Monday, January 11, 2010 by Mark Pajari
Years ago, in the early days of electronic pre press, we lived among spendy Scitex systems and huge drum scanners with 40,000 buttons, switches, dials, levers, foot pedals, pull cords and miles of rainbow-colored SCSI ribbons. We scanned in transparencies, and worked all the images in a CMYK color space (the four colors we print with - cyan, magenta, yellow and black). Although it was possible to scan into RGB (red, green, blue), almost everyone allowed the computer within the scanner to convert the image into CMYK.

Two important technological revolutions changed all that. The Internet and digital photography. The Internet introduced us to e-commerce. There was no longer a need to have all those images converted to CMYK if they were destined for a web site (RGB display) and ultimatley due to reside in a digital asset management system. And the explosion of digital cameras over the last 15 years has made the drum scanner all but obsolete. All of this means we have digital images that begin their journey as RGB (technically RAW RGB, but more on that in a future blog), not CMYK. RGB workflows are much more commonplace. But if an image is eventually going to be reproduced as ink on paper, at some point it must be converted to CMYK. Where, when and how that conversion happens is often the topic for discussion. 

And one place you can find a bunch of color geeks having that conversation is at the PIA Color Management Conference. The 11th annual conference just wrapped up last month in Phoenix. One of the sessions called "Obstacles to RGB Workflows" addressed the issue of RGB and CMYK workflows. Among the speakers on the panel was Tom Collins from Quad Graphics. He went over the pros and cons of an RGB workflow and what they were doing at Quad Graphics.

Collins began by outlining the reasons why RGB is the preferred workflow over CMYK:
  • RGB allows for greatest repurposing
  • RGB allows more latitude for color manipulation
  • RGB allows easier and more consistent gray balance
  • RGB gives you the ability to utilize L*a*b* for even greater control
  • RGB allows for consistency of separations for press when converted
  • Things like GCR and Total Ink are no longer issues at the color correction level
Then Collins outlined some Challenges with RGB workflows:
  • Untagged RGB images
    • Forces the arbitrary assignment of an ICC profile
      • He referred to this as "shopping" for the right profile
  • Issues with some vintage CMYK color technicians adapting
    • Many feel the need to 'move the black' - counters separation consistency
  • Color corrections are different, retouching is the same
  • Black-only drop shadows require work arounds
  • Workflow consistency - Requires automation

Collins discussed his experience with RGB specifically at Quad Graphics
  • Quad began full RGB workflows in 2001
  • They were forced to create custom automation for workflow consistency - hands off color management
    • Color technicians focus on image manipulation and quality, not color settings, profiles, BPC, and rendering intent
  • Quad customers demanded separation consistency, and had higher demands for color quality

Collins talked about the different RGB workflow strategies in regard to when the RGB file is converted to CMYK
  • Early-binding
    • Files coming in are converted to CMYK early in the workflow - color correction and retouching is done in CMYK - CEPS model
  • Mid-binding
    • Color correction and retouching is completed in RGB - files are converted to CMYK during an automated conversion before page assembly
  • Late-binding
    • RGB files are placed in pages and converted to CMYK in the RIP - PDF/X-3 or PDF/X-4 
Collins said that the majority of the workflows at Quad Graphics are a mid-binding, with color corrections completed in RGB, and CMYK being placed in the pages with PDF/X-1a being used. "If there are any color alterations, we go back to the RGB file and reconvert." Collins added.

Collins said that we need to raise the awareness of the concept of color managed pages in a late binding workflow.
  • Rips and color engines are improving - behaving more consistently
  • They are realizing benefits
    •  More efficient than early or mid-binding  workflows
    •  Improved color reproduction
    •  Offers the ultimate quality and flexibility with repurposing
    •  
Collins said that there are some challenges to late-binding workflows
  • There are transparency and overprint issues with PDF/X-4
  • Inconsistencies among PDF versions and RIPs
  • Most prep suppliers are still learning and may be reluctant

To sum up, Collins said that CMYK has served it's purpose (and in some cases still does), but early-binding workflows are very limiting.
"RGB (and L*a*b*) imaging provides the best quality, and is preferred to CMYK for the benefit of our customers and the end product." Collins stated.

Widen Premedia Services Video Case Study – Part II: Digital Sampling and Color Retouching

Monday, December 7, 2009 by Jake Athey

Watch the interview with Brian Becker, VP of Client Development for Widen Enterprises, as he talks about the prepress production processes performed for a large apparel marketer. Part II focuses on Widen's digital sampling and color retouching services in the life cycle of a digital asset.
 


Intro

Widen recently helped a large apparel company improve quality and streamline creative production processes by utilizing a blend of Widen premedia services and digital asset management technologies. Widen helped the client make the move from showcasing garments currently shot on mannequins to garments shot on live models for a new women's sports licensed apparel campaign. In meeting the goal of going live inside 30 days, Widen created over 500 images with 20-25% of their shots featuring garments on live models versus mannequins.

To get up to speed with the photo shoot and Widen photography workflow management capabilities, check out Widen Premedia Workflow Study Part I - Photography Workflow Management.


Color Production
The image work for the project was done by the Widen Color Production department, which consists of six master graphic artists. They are the ones that go in and clean-up the files… They take the camera raw data and optimize it for the best environment for lighting of the flesh tones, hair color, garment color, detail and sharpness, etc. Widen’s color retouching experts have a knack for understanding the customer expectations, which was very simple and natural for them given the jobs they work on every day.


Digital Sampling
The Digital Sampling department is the group that applies the graphics to the garments shot on the models and mannequins. The color operators take artwork from Illustrator and merge them onto the actual photograph in Photoshop. There challenge and expertise is to make sure the graphics follow the contours, shapes, highlights, shadows and wrinkles in the garments as they apply logos, team names, numbers and names, etc. supplied in the client's technical specs.

Many people don't realize what a huge production process there is that goes on behind the scenes to get garments sent to Widen, put on models, styled, shot correctly, color-optimized, digital-sampled, posted to a database and eventually marketed on a website or print catalog, signage, etc.


Color Management
Consumers only spend a few seconds shopping for garments online, so it’s critical that what they see on the screen is what they’ll get in real life.  We don’t use our eyes to confirm what we “think” we like on a screen, we use technical data that comes from a strong color management umbrella over the top of everything we do in production. From our cameras to our proofing devices, everything is color managed for the desired output – website or printed material.

In the end, Widen created approximately 500 images, which are upload to their digital asset library also hosted by Widen. From there, the images are ordered for placement on any number of websites. Posting images via embed links will help to ensure the most current images are used across all web domains.

The Widen Advantage caters to the life cycle of a digital asset by offering all of the production, management and distribution services under one roof. The blend of Widen premedia services and digital asset management solutions working together help clients in a number of ways, including:

Cost Savings - Increases efficiency in creative/production cycles plus centralization of re-usable assets minimizes efforts re-inventing every process of the creation-production-distribution value chain.

Faster Time to Revenue - Shortens time to market and increases effectiveness of marketing execution by empowering sales channels with on-demand access to use brand-approved digital assets.

Competitive Advantage - Improves brand consistency with quality representation of products and ensures compliance across targeted, multi-channel marketing campaigns.

Better Planning and Strategy - Tracking of usage patterns including reuse and repurposing of assets allows for more effective budgeting, resource allocation and planning of future marketing campaigns.

The 2009 PIA Color Management Conference

Tuesday, November 24, 2009 by Mark Pajari
Desert Training

While reading an on-line forum recently, I ran across an interesting quote that somebody had placed on the bottom of their post. It went something like this, "It is better to train people and risk they leave - than to do nothing and risk they stay."

In the spirit of that quote, I thought I'd devote a few words to one of the best investments in training that any company with a color critical workflow can make. Whatever corner of the industry you call home - printing, prepress or premedia services, photography, graphic design, color retouching, packaging, brand management... If it involves the need for accurate color reproduction then you should consider a presence at the upcoming PIA Color Management Conference.

To be held again at the beautiful Hilton Tapatio Cliffs Resort overlooking the sparkling desert city of Phoenix, The 11th annual PIA Color Management Conference runs from December 6th through the 8th, with a special pre conference program on Saturday the 5th. Each year the advisory board, working with the PIA (Printing Industries of America), assembles some of the top speakers in the industry that address all aspects of color reproduction and color management. Among the many excellent speakers scheduled to present this year are Steve Upton president of Chromix, Don Hutcheson from HutchColor LLC, Dave Hunter, president of Pilot Marketing, Steve Smiley from Vertis, Dr. Abhay Sharma from Ryerson University, and Kelly McCathran from Adobe Systems. 

The conference this year includes almost 60 sessions and hands-on labs. Among them...

Color Meets the Frontier of Electronic Paper
Dr. William Ray with NthDegree Technologies Worldwide, discusses how color management is applied in the developing field of Printed Illuminated Paper which lights up and creates the illusion of motion. He has created a unique color model for emissive color that draws on both RGB and CMYK.

How to Compete in the Global Marketplace with Monitor/Softproofing
This session covers how adopting soft proofing will help you save money on materials, labor, time and transit costs. This session will give examples of companies that made the switch from contract proofs to soft proofs and saved themselves and their customers money.

Real World RAW from Large Format to Digital SLRs

Steven Johnson, world renown photographer and last year’s excellent keynote presenter takes a look at where we are in color management and where the technology is going as it relates to the uninterrupted stream of data in RAW workflows. 

RGB Working Spaces

Don Hutcheson discusses the difference between RGB working spaces and how to choose the correct space for Web, publication, fine art photography, RAW export, image archives, etc. He will talk about the benefits to wide-gamut spaces, and if there is one perfect RGB space for all work.

The program this year also includes two great keynote sessions...

Delivering the Color for Broadway
Representatives from King Displays, a Manhattan printing company, will discuss how they produce 90 percent of all the signs and displays for the Broadway theater market. Everything they produce is color critical and they will show how they meet the needs of a distinct clientele with demanding color needs and quick turnaround times.

Forecasting the Right Colors

James Martin, the president of the Color Marketing Group, will discuss how his group of color designers comes together each year to collaborate and then interpret their shared information into salable colors that will ultimately make up the color directions for all industries, manufactured products, and services.

I can speak from experience that this valuable, one-of-a-kind conference is very much worth attending. Color management technology is still in a state of evolution. Whether you live in the world of print or the Internet, every year new products, best practices and procedures are developed that benefit everyone involved in the exchange of color. See the PIA Color Management website for more information.

News from Print 09

Tuesday, September 29, 2009 by Mark Pajari
From Way Up On Top of the Carpet Padding...

Just like the opportunity for voters to find new users of the official White House stemware, the mammoth Print 09 trade show blows into the windy city every four years. Chicago's cavernous McCormick Place was once again the site for the six day event that showcases press, converting and finishing equipment manufacturers along with premedia and prepress service providers.

From most of the exhibitors that I talked to, attendance during the event started off slow on Friday, but picked up as the show progressed. Many did think that overall the attendance was down substantially from Print 05. However, when I was there on Monday (day 4), it was at times difficult to talk with some of the vendors, as many booths I visited were packed with attendees. I suspect the same would not have been true on Saturday or Sunday given the beautiful weather in Chicago.

Whether it is Graph Expo or Print, I think the square footage of the floor space that some companies occupy is in direct proportion to the amount of padding that is placed under the carpeting in their booth. Take a few of the larger exhibitors like Heidelberg, Xerox, or HP for example. I actually had to use a rope ladder to climb onto their floor space. Once I was up there, I had to crouch my 6' 4" frame at times to keep my head from coming in contact with the structural support joists for the McCormick Place roof. And then it was like walking on a Tempurpedic mattress. 24 feet of memory foam under foot takes its toll eventually. I heard several people were taken to the hospital for falling off of the carpeting.
 
Okay, on a more semi-serious note, here is some random thoughts from just a few of the 650+ exhibitors that occupied the more than 460,000 square feet of floor space...

                  
Where was Ed McMahon? The K-Zone in the Kodak booth featured a live studio audience, cameras, a desk, a couch and a line up industry experts expounding on the value and relevance of print, but no stupid pet tricks. 


A lot of the buzz I heard was based not on what was there, but what was NOT there. Namely any equipment from Kodak. In a bold move, they instead chose to fill their booth with a bunch of interactive information kiosks. They also had a large set, called the K-Zone, where they conducted interviews of various industry leaders in a talk show format. It was exactly like "The Tonight Show with Conan O'Brien", except a lot less funny. I thought the Kodak booth was well designed and it seemed to be pretty crowded every time I walked through it. Some people where a bit put off that they did not show any equipment. I give them credit for at least trying something different. At the very least, they generated a lot of buzz throughout the show.

                          
Anyone for air hockey with a marketing spin? Kodak's booth included a large touch sensitive table that featured large digital "pucks" that floated by. When you touched a puck, it would open up scrollable pages of information on a particular Kodak technology. You could collapse the pages back into a puck and flick it down the table, bouncing off the edges like an air hockey table. It was sort of like a giant low resolution iPhone without all the cool apps.
 
 
Kodak also had a pretty cool handout at the show...Their magazine called "One" had a 5 mil clear polyester outer cover printed on a Gallus EM 510 S press. What was unique about it was that it showed an image on the outside printed (from the inside) with 20 micron stochastic screening and another image printed with a 200 line screen on the inside. It was essentially four color process, two hits of white, and another four color process on top of that. A nice flexo project showcasing their Flexcel NX Digital Flexographic System.

FineEye Color Solutions (formerly known as Chromaticity) introduced the ICE (intelligent color engine) technology in the form of the ICEserver. The ICEserver is a Mac based application that processes PDF files before imaging on a CTP, inkjet or color controller RIP. It takes a different approach for converting files from RGB to CMYK. It recalculates color conversions with new algorithms, accounting for paper color values. Programmed Color Reformulation (PCR) is built into the ICEserver which functions in a way like GCR - replacing some CMY with black. They claim ICE yields a 20% increase in gamut with existing CMYK inks; 25% average reduction in ink use; increase in dynamic range and contrast; faster makereadies and it equals gray balance and tonality of GRACoL and SWOP. The before/after color samples they displayed in their booth were impressive. They intend to have another ICE product out early next year - ICEmaker which will be a Photoshop plug in using the same technology for color separation. Hmmm, that makes me think... maybe Widen should OEM their ICE technology and incorporate it into our digital asset management software. We'll call it ICEdam. And we'll call our Widen Appliance server ICEcube. And then there will be ICEberg to sink large ocean liners carrying Leonardo DiCaprio, and... Okay, I'll stop now.

What was the deal with the AT&T coverage in the McCormick Place exhibit halls? Can't a guy get a decent Internet connection on his iPhone so he can tweet? And don't get me started on the $12 burger in the Plate Room food court that tasted like a sweaty shin guard.

                  
Hey, that's cheating... At first glance, it appeared the Agfa booth was buzzing with excitement from all the people packed in like sardines. Upon closer inspection, it turned out that their booth was populated with scores of 2 dimensional visitor cut-outs to make the booth look more crowded. Imagine, an exhibitor at the Print show printing it's own attendees. Hmmm...


Just Normlicht, the German manufacturer of light booths and desktop viewers was showing off their new LED Color Viewing Light. The desktop viewer uses new LED technology to replicate almost any standardized light source. The new LED technology also offers the ability to simulate any light source with or without the UV spectrum allowing for easy viewing of the effects of optical brightening agents found in many commercially available substrates. The consistent color in these booths can be maintained for 25,000 hours - 10 times as long as a standard booth containing fluorescent tubes. They had these new LED products on display along with their line of Just colorCommunicator booths which are equipped with a USB interface for calibrating the intensity of the standardized lighting along with the monitor. For more information on the pricey new Just LED booths, see my previous blog post called, Let there be LED.

GMG introduced the ColorServer Plus - A new color management solution specifically designed to allow companies to consistently print to an industry standard (GRACoL) on a digital press to achieve color accuracy. At Print 09, GMG announced the use of GMG ColorServer Plus driving an HP Indigo press. ColorServer Plus uses GMG’s iterative profiling approach to establish a precise calibration state of the digital printer as well as conformance to a specific industry or in-house print standard.

I think I'll skip the $12 burger at Graph Expo 2010.




Photoshop Color Retouching and Manipulation of Layer Effects on a Digital Asset Part 2 by Matt Anderson

Monday, September 21, 2009 by Matt Anderson
For this example I will show you how to create some cool chrome effects on a digital asset. A high end furniture store wanted a nice looking catchy banner created for display. My direction was a certain color palette along with a neat chrome effect. To accomplish this task I used the powerful possibilites of Photoshops layer effects. At the end of this blog entry I will actually let you download the final .psd digital asset. (It has been resized.)

Here is the final image.


Achieving this effect required just about every trick that layer effects offers.

Here is a screen shot of the layers palette on the final photoshop file.

Step 1 - I type set both lines of copy
Step 2 - I created an upper and lower bar with the path tool
Step 3 - I created a midnight blue background with an inner shadow effect
Step 4 - I applied a drop shadow, inner shadow, inner glow, bevel and emboss, color overlay, gradient overlay, satin and stroke to the text and bar layers
Step 5 - I also applied a Hue/Saturation and Curve adjustment layer to each of the type layers for additional color correction and contrast.
Step 6 - Using an air brush that fades, I painted white strokes for a nice catch light


Here is an animation of the layer effects settings I used.


*Hint* an easy way to copy and paste layer effects between layers is to control(Mac) click on the layer effects you want to copy (in the layer palette) and select copy layer style. Next, select the layer(s) you want to apply the layer effects too, control(Mac) click and select paste from the layer style option. Now your layer style is quickly applied to the new layer.

Photoshop Color Retouching and Manipulation of Layer Effects on a Digital Asset Part 1 by Matt Anderson

Monday, September 21, 2009 by Matt Anderson
For this next example I am going to use layer effects to recreate a mirrored look on some expensive trendy glass tiles. My client provided me a digital asset of mirror glass tiles that reflected a dark room. The ambient room lighting provided a dark and unattractive reflection. To create a more appealing and marketable appearance I recreated a traditional mirror reflection using Photoshops layer effects.

Step One - Using the pen tool I masked off all in interior contents of each fragment.
Step Two - Using the pen tool I masked off all the glass tile from the grout.
Step Three - I made a selection from my glass tile path to mask off the layer effects.
Step Four - I made a selection of the grout and with color manipulation I neutralized the warm cast of the grout.

Here is the before, mask of tile, and final look of the expensive glass tile digital asset.
Glass tile animation


To accomplish this layer effect I did the following:
(Tiles are masked on their own layer)
  1. Created a Drop Shadow
  2. Created an Inner Shadow
  3. Created an Inner Glow
  4. Created a Color Overlay
  5. Created a Stroke
Using these settings in tandom provides a reflection more in line with what consumers are use to seeing in brand marketing of reflective pieces. (The soft white neutral cloudy nature.)

Here is an animation of the layer effects settings.

My final step was to use the grout selection and desaturate the warm casted grout.

Here is one of my clients high quality pieces of furniture. My task was to take this digital asset and create a sense of motion for the self closing door feature. Accomplishing this task required digital media management of three separate exposures. The door is strategically placed in various positions. Using photoshop, I digitally sampled the opacities to 55%. Color correction and color retouching had to be performed identically to each layer.

The first layer represents the slightly open door at 100%.
The second layer I have added a slight ghost of the door in it's closed position.
The third layer I have placed the door in it's 2/3 closed position at 55% opacity.
The fourth layer I have placed the door in it's 1/3 closed position at 55% opacity.
The final layer I masked off the door in it's original position, allowing the motion portion to be seen underneath. When done correctly, the color manipulation will yield a natural looking temporal scenario for the auto close feature.

IPA Color Management Professional Certification

Tuesday, September 8, 2009 by Mark Pajari

Last year, the IPA introduced a new educational program aimed at certifying individuals responsible for color management and color reproduction. The IPA Color Management Professional certification program begins with an extensive course on Color Management Fundamentals. This acts as a prerequisite to three additional courses focusing on different areas of expertise: Color Managment for Photography, Color Management for Prepress and Color Management for Premedia.

These courses were developed by noted industry color experts including Dave Hunter from The Pilot Marketing Group, Lou Prestia of Prestia Color Consulting and Steve Upton with Chromix, among others.

Each course contains a series of online videos totaling 2 - 3 hours in length. After completing the videos, students take an online exam based on the information presented in the videos. The initial CMP-Fundamentals exam consists of eighty questions selected from a randomly mixed question “pool” so no two exams are alike. Students must answer 80% of the questions correctly to pass the test and become certified.

Individuals that have a good base knowledge of color management can opt for the exam-only option of the Color Management Fundamentals course. I recently took this 80 question exam and I can tell you that it was a challenge (and YES I passed, thank you). The questions spanned across all aspects of color management, and often were situational. Some questions made me scratch my head and really think it through. See a complete list of individuals that have achieved IPA CMP certification here.

                                     
If you are responsible for color reproduction in any way - from photography, design, prepress production, premedia services or any similar areas, I highly recommend pursuing color management certification. It serves as not only as a great learning experience, but also to reaffirm your knowledge level. This is the first time that the industry has had such a comprehensive program in place. I applaud the IPA and the professionals that put this course together.

Winds of Change (?) From Kodak

Tuesday, July 14, 2009 by Mark Pajari
In my previous blog, You can have my last roll of Kodachrome, Paul Simon., I discussed the recent announcement by Kodak to stop manufacturing Kodachrome film. That made me think about a promotional video I saw a couple years ago. Kodak was the sponsor of a keynote address at the 2007 PIA Color Management Conference in Phoenix. At the beginning of the presentation, the representative from Kodak played the video to get the message out that the old Kodak has left the building and they are now poised to play a major role in the future of digital photography... If you believe that... I don't. Kodak came late to the digital photography party, instead putting too much stock in their lucrative film business.

Anyway, the video received a great response from the audience. See it for yourself below - it's actually pretty funny.




Furniture Iterations

Monday, May 4, 2009 by Matt Anderson
Some of the color retouching work that comes across my plate is high end furniture. (Baker, Pennsylvania House, Canac, Durham, Thomasville, Broyhill, La-Z-Boy, Flexsteel, are all clients I have done extensive color correction and retouching for) If you have ever worked furniture you will know it’s tricky and tedious. Wood tones are tough to photograph and a considerable amount of prepress color correction is necessary for good quality separations on press (GRACoL, Swop 3, Swop 5, etc.). Every piece typically needs its own mask and the furniture group requires multiple asset versioning because of the countless possibilities of wood and finish types. I’ve quickly assembled an animated gif file showcasing some color manipulation for a typical furniture sell sheet. This particular scene is a file I worked many moons ago for Pennsylvania House. The scene required color and texture changes. Additionally, the customer required prop alterations and a window added.


The wood furniture was masked with a path via the pen tool. The plant was masked off using the green alpha channel with some dodging and burning. The rug textile was edited with vanishing point. Also, the window was added with vanishing point with additional cloning. The bed spread and pillow cases had shaping and bending via liquify. The shadow on the bench was created using an air brush with a fade. The final file on this particular shot was printed at approx. 9" x 12" at 300 dpi, 175 line screen, GCR 320 on a coated sheet fed stock.

PIA Color Management Conference: Take 7

Monday, April 13, 2009 by Mark Pajari
Stephen Johnson Keynote: Photography and Realism

Internationally recognized digital photography pioneer, designer, author, and teacher, Stephen Johnson spoke during one of the keynote sessions at the recent 10th annual PIA Color Management Conference in Phoenix. His photography explores the concerns of a landscape artist working in an increasingly industrialized world. His international teaching has led him to England, Scotland, Ireland, Germany, Sweden and Mexico, and on two voyages to Antarctica. Johnson's photographs have been exhibited, published and collected in Europe, the US and Japan. In 1999, Folio Magazine declared the publication of Johnson's digital photographs in Life Magazine to be one of the Top 15 Critical Events in magazine publishing in the twentieth century. He is arguably the Ansel Adams of our time.

The underlying theme to Johnson's presentation was that the whole advent of digital photography represents a whole new level of the ability to record reality.

Photography Aids Conservation Movement
Johnson said that early photographs were instrumental in the development of the national park system. "There is a long tradition of photography in the environment. And the reason that relates to me for color management is because ultimately these places are wondrous almost beyond belief. And we've had lots of different ways of looking at them over the years in various states of unreality." Johnson said. "There is a greater power now to portray them for what they are, both in their beauty, their nuance, their subtlety, and their wonder. And along those lines, I've spent a great deal of my adult life." he added.

Writing With Light
"Photography means writing with light. It is in fact a depiction of what was before the lens. It has nothing inherently to do with pushing pixels around after the fact. You do not fix a photograph in Photoshop, you make a photograph in the camera. You try and process the photograph into something use able in Photoshop." Johnson stated. "Very rarely do you take a lousy photograph and make it interesting in Photoshop. More often you end up wasting a lot of time, and may end up with something that is even uglier than what you started with." he added.

Johnson said that the photograph is made at the moment of inspiration. He emphasized that photography is a sort of enchantment that you then distill. He said that it is a fascination with a place, a moment, a passing of events where you are trying to distill it down to a two dimensional representation that can be fit into the color or dynamic range  capabilities of the camera. He referenced photography to what Van Gogh said about his own work - That his job was to exaggerate the essential and leave the obvious vague. "That's where photography rises from document to artwork." Johnson said.

"I don't believe that photography talent has anything to do with manipulating media. I still believe that despite this ability in the digital age to manipulate images into being almost anything other than what they were, the fundamental power of photography is the fact that we believe it." Johnson said.

Johnson displayed a number of examples showing how photography has been messed with for a long time in lots of different ways...

        
Examples of photographic manipulation: A famous Civil War photo depicting a Gettysburg battlefield scene (left) by Alexander Gardner is controversial because some claim that he actually went into the scene and moved the body of a dead soldier around to get a better photo. A more current photograph (right) published by the Weekly World News shows President Clinton shaking hands with an alien. This photo manipulation helped sell a lot of t-shirts and other memorabilia. Or is it real, and this explains a lot about the Clinton Presidency? Hmmm...

Hyper Color Photography
Johnson spoke about the current state of color photography in landscape, "...The contemporary stylistic choices are one of exaggeration, heavy contrast and a world bathed in the perpetual golden light of eternal sunset. Of deep saturation... where we get this sense of hyper, intensified reality. It was bad enough before Photoshop. Boy is it bad now!" Johnson said. "It's gotten to the point where hyperbole is the medium and there seems to be an irresistible relationship between the hand and the saturation slider in Photoshop that just can't resist being pulled over to the right." he added.

Johnson asked the question, "What does the world look like to your eyes? Does it look like this hyped up reality? Is the world that we are capturing somehow lacking, so that it needs enhancing? To enhance a photograph, by definition, it seems to me to be talking about a bad photograph, a boring place or an untalented photographer." Johnson said.

"When we get to the idea of photography and reality, it's gotten to the point that photographic views of the world are so pervasive, that we expect the world to look like the photographs." Johnson said. To prove his point he told the story about an experience he had at the edge of the Grand Canyon on a hazy day... He was watching people get out of a tour bus, walk up to the edge of the canyon, look out over the hazy scene and say, "It sure doesn't look like the postcards" as they turned around and left. "Their preconceptions had been so skewed by these photographic exaggerations, that they weren't even willing to consider looking at the real place. That says a great deal on how photography has influenced our perceptions." Johnson said.

              
"It's called fog..." was Johnson's response one day when asked by an art director what went wrong with this seemingly washed-out photo of Misty Lake at Arcadia National Park in Maine. This example underscores his approach to photography and realism.

He asked if shadows are, in fact, black. He said that if you look at any magazine, you will see plenty of black shadows, yet if you walk outside, black is not the overriding feeling that you get. "Photography has grown into a harsh, dark, somber view of the planet earth.... The world is a troubling place, but it is also a delightful place. A place filled with light, not filled with darkness. Your photographs don't have to reflect that." Johnson said.

The Digital Epiphany
Johnson moved on by discussing the difference between film and digital sensors, and the day film died for him in 1994. "It was a brutal and ugly death." Johnson confided.

          
The enlargement above of a San Francisco street scene taken in 1994 shows why Steve Johnson realized that film was going away. The top image shows detail from 4x5 E100 transparency film scanned with a Linotype Tango drum scanner. The bottom image is the same detail from a prototype BetterLight digital camera back. He said that was the point he knew film was dead as he looked at the difference between the two images.

Johnson discussed how with digital, we can shoot RAW and balance on something known to be gray and get some degree of accuracy in the original color reproduction.

He then reviewed many different photos from his years of work within the US National Park system.

"Maybe it's time to get out of the way and let the beauty we see, be the beauty we try and record. Real light and color from the most ordinary scene can have an intrinsic beauty. I continue to be amazed at the narrow vision, the blinders that so many people have on, as they walk around the world and don't notice things. Even photographers, who have the audacity to characterize the planet earth bathed in the sun's light as sometimes being "bad light". They have to wait around for the "good light". What a huge opportunity missed..." Johnson said. "Being a witness to wonder is what photography is about." he added.

Johnson concluded by reminding the audience that there is a ways to go. "We are not in an age of digital photography. We are in an age of electronic photography that we are digitizing. The Bayer pattern itself is an early-on in the process technology. We need to be able to color manage our cameras - having a spectrophotometer in the cameras, understanding the sensors color capabilities and starting to move toward image specific profiles is where we need to go with digital cameras." Johnson said.





Color Correction, Retouching, and Manipulation #1

Tuesday, April 7, 2009 by Matt Anderson
Cover Girl Retouch

Here is my debut blog entry numero uno. I decided to post a shot of a beautiful woman I photographed a while back. (Thanks Cindy!) If I recall correctly the lighting was setup as follows. 60" umbrella high camera right and left, large gold reflector on a table near her waist for lower fill. A kicker hair light above with a grid. Nikon D200 f/10 105mm Micro, speedotron blackline lights sync'd at 1/200 second. I have posted an animated gif file that is limited in color depth (256), but handy for showing the various layers in action.



Original Layer: You can see some bad default settings on the RAW file. WB, exposure, detail, etc.

Figure 1
: The following were done in CS4's ACR 5.3 RAW editor. I have adjusted WB, exposure, sharpening, selective clarity (pos & neg via the adjustment brush). Also in the tone curve tab I have made a curve that adds pleasing contrast.

Figure 2
: Now in CS4 I created a new layer and did the following.
Dodged the background to white. Using curves I added additional contrast making an S-curve. Used the healing brush to minimize moles, creases, and wrinkles. Air brushed on darken mode the unwanted highlights. Cloned in some additional eye lashes. Using the color saturation adjustment I selected her teeth and dsat -10% and brightened 10%.

Final: I created an additional layer for these final tweaks. Manipulation via the liquify tool to shape and sculpt. Cloning for additional fill of weak spots in the hair areas. Masked off the necklace and diamond to brighten and color correct in curves. Made selections in her eyes to darken the centers, brighten the color of the iris, and control the light reflection spill-overs. Burned in additional weight in the eye lashes, eye brows, and cheek areas. Applied a curve that opened up the shadow area's via the history brush. (Using curves open the models skin in the mid-tones and shadows, set this as your history state to brush from, go back in the history palette prior to the move, and with 1% flow, begin brushing in the effect.) Using the air brush on 70% fade, I created a starburst catchlight for the diamond. I know much of this retouch on the final is "over the top", almost cartoonish. My intent is to show you a little bit of what is possible with various tools and adjustments.

Notes: First and foremost proper lighting and camera technique is a must for decent results of any subject. Secondly good masking (or hand technique with a digital brush) is crucial for top results. Third, your monitor must be calibrated accurately for professional results. Premedia color correction, color manipulation, and color retouching take time and lots of practice. Like many things in life, the more you do it the better you get. Finally have fun and experiment.

I hope you have enjoyed my first blog entry. Stay tuned for more...

PIA Color Management Conference: Take 6

Color Management: 10 Years Back and 10 Years Forward - How Times Have Changed: Part 3

This session at The PIA Color Management Conference featured three industry experts who took the audience back in time and then took a peek into the future of color management technology. I will cover each speaker's presentation in a separate blog post. This post covers Dan Caldwell's presentation.

Dan Caldwell
Dan Caldwell is the president of operations at ICS (Integrated Color Solutions, Inc.) Dan was one of the brains behind ColorBlind software form the late 90s and he is now producing cutting edge solutions at ICS, like Remote Director (soft proofing software). Dan spoke to the future of color management.

Still Too Complex
Dan began by saying that color management is still too complex. In order to make it easier for everyone to use, color management needs to:
  • Move into the subsystems
    • That's starting to happen, but it's not there yet
  • It needs to become transparent
    • So that we are using it but we don't know we're using it
  • All devices need to be self calibrating
  • All software needs to call on those calibrations
Dan got a chuckle from the audience when he said all the above points were pulled from a ColorBlind presentation from 1999. Meaning that we are still facing some of the same issues as we did 10 years ago. "We've made some strides here, but this is still a valid list of where we need to go in the future." Dan said.

The future of color management will involve the displays becoming much more important. Remote proofing and collaboration is becoming a bigger part of our workflow."Soft proofing will become much more accepted." Dan said.

We will see more and more large gamut displays. The color and luminance consistency is better and the resolution is getting higher.

We need automated verification of ICC profiles, the CMMs, workflows and documents. Systems need to verify that they are color accurate, you can't just assume they are accurate. Dan pointed to Maxwell from Chromix as one tool that is providing this feature. 

Dan wrapped up by predicting where we will be in 2018:
  • All ICC profiles will be spectral based
  • All applications will assign color handling automatically
  • All systems will call on color management by default
  • Monitors will handle ALL proofing
  • Microsoft will introduce a working color management solution (laughter)

PIA Color Management Conference: Take 5

Color Management: 10 Years Back and 10 Years Forward - How Times Have ChangedPart 2

This session at The PIA Color Management Conference featured three industry experts who took the audience back in time and then took a peek into the future of color management technology. I will cover each speaker's presentation in a seperate blog post. This post covers Steve Upton's presentation.

Steve Upton
Steve Upton is the president of Chromix, maker of tools like ColorThink - something which is in the arsenal of any true color geek. He is a popular speaker at trade shows and conferences. See my previous blog post on his excellent article called "The Color of Toast" which explains color managment technology in everyday language.

Although Steve was charged with speaking about the current state of color management, he confessed that he spends a lot of time looking forward in the color management world, and looking at it optimistically. "I think it will all be wonderful, but hopefully not too wonderful. Over the years, if there is one thing I've learned, it's go where there's chaos.... If everything works perfectly, there's no work for any of us in this room." Steve said.

Current Developments in Color Mangement
There are some interesting things happening today that are worth watching, yet they have some challenges that surround them...

• Integrated Measurement
Building a good ICC profile doesn't solve color management. Keeping a single device calibrated doesn't solve color management. Some new printers have full-blown spectrophotometers on board and the potential to support other types of media other than the one the manufacturer wants you to use. "Integrated measurements is a good idea. And for those machines that have them, it appears to be working quite well." Steve said.

But Steve did caution that it also presents an interesting challenge. He told a story of a large creative agency in New York that had an HP and Veris printer, both with integrated measurement, and and Epson with a conventional prepress RIP in front of it. All of the printers were in the same room, but could they not get them to match each other. The printers all did there own stuff internally. "It's not the be all, end all, but there are benefits." Steve said.

"Hopefully over time we will see more and more consistency between the different technologies that are offered, so that more of these systems will match more automatically" Steve said.

• Cheap Instruments
The EyeOne Pro is a good low cost spectrophotometer and you can get good quality screen calibrators for $150 to $200 with decent software. "But a whole bunch of cheap instruments out there doesn't mean that everything is going to get better." Steve said.

• Large Gamut Displays
"These new flat panel displays are blasting light at us in incredible volumes. Which by comparison make your prints look too dark. But the printer is not the problem. The displays are way too bright [before you calibrate them]." Steve said. But he did add that it can be a good thing, because it means you can bring the light around you up more. "You don't have to work in the caves anymore" he added.

The backlight in flat screen technology is changing. Were moving from florescent tube to white LED. And beyond that, are three color LEDs so now you can balance RGB (white point). But there can be uniformity problems.

"When you graph these new large gamut displays in 3D, you see that there are colors you can get on press (like cyans available in SWOP), that now can be viewed on these displays. So it's another step to making soft proofing more reliable. We will see a lot of advancements in display technology in the next ten years." Steve said.

• Display Port
Apple's new Display Port technology is like USB for displays. There is the potential to hook up more than one display to a single port and the potential to do high bit depth through it.

• SWOP GRACoL specifications
New specifications like SWOP3, SWOP5, GRACoL, G7 have created a new set of reference data. Up until now with Photoshop we had one profile for US use: SWOPV2. We now have a unified way of doing things. "It's a renaissance in US printing for standards." Steve concluded.

PIA Color Management Conference: Take 4

Thursday, April 2, 2009 by Mark Pajari
Color Management: 10 Years Back and 10 Years Forward - How Times Have Changed: Part 1

This session at The PIA Color Management Conference featured three industry experts who took the audience back in time and then took a peek into the future of color management technology. I will cover each speaker's presentation in a seperate blog post. First up is Dave Hunter...

Dave Hunter
Dave Hunter, President of Pilot Marketing and one of the founders of the conference, discussed the previous 10 years and reflected back on how things have changed since the conference's inception in 1999.

Dave began by talking about what he referred to as the "bleeding edge technology" of color management. "Bleeding edge technology means that the technology doesn't always work, and when it doesn't, you get cut. And depending on how bad it doesn't work, you bleed. And sometimes you bleed a lot. If I knew then, what I know now, I wouldn't be up in front of you talking today. Because I've lived through a lot of bleeding edge technology." Dave said.

Proprietary Systems
Looking back 10 years, Dave said that initially it was a very proprietary color world. Prepress color management systems only interacted with themselves, not other systems. The formation of the ICC in 1993 gave the industry an open platform so companies like Aldus, Adobe, Quark along with different RIPs could share the same profiles.

"Remember Pagemaker?" Dave asked while he talked about some of his early experience with color management when he was with Aldus. He would attend summit meetings with top software manufacturers (Agfa, Apple, Adobe...) to work through color problems. Dave said he learned a lot in those early days by writing down notes and listening to the conversations.

Dave discussed the state of the art in profiling in 1992. "At Kodak's labs in Bedford, MA, the hand held spectrophotometer took two of us to carry across the room, and costed around $15,000. "There were three of us that would take turns reading a 1,000 patch output target, one patch at a time. It would take approximately six hours to do. And to process this profile, would take about eight to ten hours." Dave said. He added that the state-of-the-art Mac IIci that was used would crash about half of the time. "An output profile would literally take 16 hours to make." Dave said.

The Holy Grail
Dave continued his stroll down memory lane by reminding the audience when color management was sold as the Holy Grail. Color management was oversold as something that will take bad images and make them good or "Child's Play" as Lino Color used to say. Or "Perfect color with your eyes closed." as ColorBlind claimed. "It never met expectations, and it was getting a pretty bad reputation because it was this never-ending promise that was never fulfilled." Dave said.


    Anyone Remember this claim? "Perfect color with your eyes closed." Really?

Apple Trouble
Dave spoke about the turmoil at Apple in 1996 - 1997. In 1997 Apple considered dropping ColorSync until they figured out that it was unique and catered to it's core users: graphic arts and printing. Since then they have put a lot of resources into ColorSync and it helped save Apple as a company.

Some of the companies from 1998 that were making software or hardware for color management: Color Savvy, Logo, RIT80, Praxisoft, ColorBlind, Fuji, LightSource, Monaco, Optical, Heidelberg, GretagMacbeth, Techkon, Sequel Imaging. "Many of these companies are not around anymore." Dave said. He also referred to what he called the 2008 X-Rite Empire. LightSource, Monaco, GretagMacbeth, Sequel, Logo and Pantone are now all part of X-Rite. And although X-Rite bought out GretagMacbeth, Dave pointed out that more of the recent product releases have been GretagMacbeth products.

Enabling Technologies
Dave expanded on some of the enabling technologies to color management throughout the last ten years:
  • LightSource Colortron 1997 - 2001
    • First hand held sub $5000 spectrophotometer ($1500)
    • Used software on a computer for intelligence
  • ColorBlind software 1997 - 2000
    • First to use 3D modeling so you could see what was happening with gamuts
  • Standards Committees
    • Dave McDowell, Larry Warter, Mike Rodriguez, Larry Steele worked tirelessly to provide the framework that enabled all of this color management technology. "These guys don't get enough credit. Because without them, this industry would really be in disarray." Dave said.

Education is Key
Dave wrapped up by emphasizing that education has always been an issue and it is still lacking. "I liken the analogy of color to an onion. Just when you think you know it all, there is another layer. And I'm still peeling back these layers of the onion because there's so much to it. And still crying along the way" he joikingly added.

Assigning, tagging, converting, and embedding ICC profiles in Photoshop

Tuesday, March 24, 2009 by Mark Pajari
Fun with ICC Profiles... Okay, "fun" is a relative term...

The question I'm asked most often is, "Do these socks make me look fat?" Another question that I'm often asked, but is not nearly as weird is, "What's the difference between assigning, tagging, converting and embedding an ICC profile in Photoshop?"

I'm glad you asked. Here is the answer....

Assigning a Profile
When you assign a profile in Photoshop, you are telling the program the meaning of the RGB or CMYK values. For example, you are telling Photoshop what specific shade of blue is represented by 46R 169G 232B. When you assign a profile, you do not change any RGB or CMYK values in the file, only the way in which those values are rendered to your display within Photoshop. To say it another way, you are changing the appearance of those values, not the values themselves. When you use the Assign Profile function in Photoshop (found under Edit) you can also remove a tagged profile by selecting Don't Color Manage This Document.

Tagging
Tagging a file with an ICC profile is pretty much the same thing as Assigning a profile. Many people use the terms Assigning and Tagging interchangeably.  

Converting
Converting lets you convert a file from it's profile space (or if the image is untagged, the current working space) to any other profiled color space. Here, the goal is to change the RGB values, not necessarily the color appearance. Typically a Convert to Profile function (also found under Edit) is used to convert a file from RGB to CMYK. The dialog box displays the source profile and allows you to select the destination profile along with other options like the rendering intent.  Using Convert to Profile is always a better way to convert a file to CMYK because it gives you much more control than simply selecting Image - Mode - CMYK.


Convert to Profile
        
The Convert to Profile dialog box in Photoshop is used to convert an image from one color space to another using ICC profiles.

Embedding
When you embed a profile, it simply means that you are including that profile in the file when you save it. You are including a little meta data with the file that conveys your color intentions to everyone downstream in the workflow. It is for this reason that it is generally a good idea to embed ICC profiles in every image.

There are a few exceptions to embedding profiles. One instance is in a more closed-loop CMYK workflow. If all your images are destined for a standard press condition, you know that no one will be opening or editing your files any further, and you have converted all the files for that press condition (SWOP3 for example), then in a sense you have already tagged the file with the appropriate profile when you did the RGB-CMYK conversion.

Or suppose you are sending out a bunch of RGB images for a Web site. Microsoft Internet Explorer doesn't recognize ICC profiles (Safari and FireFox do), although Windows Vista does treat untagged images as sRGB.  Embedding profiles also increases the file size to a degree, which is not a good thing when you want fast-loading images on a Web page. For now, it's best to just convert Web images to sRGB and call it good.

And no, those socks don't make you look fat.
