To be useful the shot of the chart need only be reasonably well exposed and must be in the exact same lighting conditions of the scene or subject you are shooting It need not even be sharp or in focus It need not fill the frame as in these example shots however it should not be so tiny that you can t zoom in from within Camera Raw and get a usable sample size By the way the eyedropper in Camera Raw is a fixed pixel size of 5x5 monitor pixels regardless of the zoom percent So while you can t change the fixed sample size you CAN substantially change the effective sampled area At 100 the sample will be 5x5 actual image pixels At 50 zoon the sample will be an effective 10x10 image pixels At screen zooms bigger than 100 the effective size remains 5 x 5 Canon 0 300 C6046 CRW OSO 200 180 172 100 md After clicking in the sample area Camera Raw uses the color readings to do a very accurate white balance correction Under the white balance settings the drop down menu will read Custom You can choose to manually adjust the resulting white balance to warm or cool or alter the tint Generally only a very slight adjustment will be required 2004 by Jeff Schewe ALL RIGHTS RESERVED no reproduction allowed without expressed written permission 20 A Digital Workflow for Raw Processing By Jeff Schewe A wise investment of time for Camera Raw users is to shoot a color sample in the variety of lighting conditions t

10. A Digital Workflow for Raw Processing By Jeff Schewe Part Three White Balance As I ve indicated before the white balance of any raw conversion is absolutely critical So critical that I feel compelled to spend an entire section to it exclusively Most of today s cameras that allow saving captures as raw files also allow a user to set a white balance while shooting However when shooting raw this white balance is only saved as an EFIX metadata tag In point of fact when shooting raw the only camera setting that will have a significant impact on the raw capture is the camera s ISO setting The ISO setting changes the analog to digital conversion process by amplifying the signal from the sensor Virtually all other camera settings a user may set on camera will only result in an informational tag that conversion software may or may not use when processing the raw conversion When shooting jpg s these settings DO effect the resulting recorded file To be honest it s amazing that the on board camera DSP chips can do a raw sensor capture to gamma encoded and jpg compressed recorded file as swiftly and accurately as they do However when it comes to raw capture the raw file does not receive any significant post capture image processing I say significant because some cameras do have some settings that may influence aspects of the resulting raw capture but for the current issue of white balance let s assume that raw is raw Canon EOS 30

20. A Digital Workflow for Raw Processing By Jeff Schewe Introduction Be careful what you wish for Famous last words but it seems now that more and more photographers have gone digital they ve pretty much got what they wished for perhaps too much Shooting digital 1s extremely liberating and gives you immediate and total control over your photographs But and there s always a but it seems like digital processing can take forever In the old days photographers and clients would mull over Polaroids then the photographer took over and exposed film that nobody could see until it was processed You wrote up the work orders for the film and dropped it off at the lab Next day you got a nice package with all these rolls or sheets of film that you could drop on a light box to loupe and inspect generally with nobody to bother you Yes there was always the possibility of a lab screw up but that rarely actually happened More likely the client was told the lab screwed up the film to offer some measure of conflict avoidance and pass off a problem the photographer had on the shoot Well those were the old days Some aspects were good but that was then and now very few photographers still shoot a large volume of film for delivery Now it s shoot digital check the camera LCD download the files edit on the monitor color and tone correct do web photo galleries or other proofs collect all the files for delivery and burn to CD and

46. retagMacbeth Color Checker I would suggest visiting Bruce Lindbloom s web site http www brucelindbloom com On his site he has ColorChecker readouts for a variety of RGB color spaces all of the color spaces included in Camera Raw You can use the reference numbers to better tune the color rendering of the various patches and achieve an even higher degree of accuracy by using the Eyedropper tool to check the patch colors Note the only way to use the numbers is when you have an absolutely perfect white balanced image with absolutely no Exposure Shadow Brightness Contrast or Saturation corrections The shot of the Color Checker must be perfectly lit so no anomalies occur regarding fall off of light It can be a useful exercise to accurately adjust your color rendering On the other hand it can also be frustrating to try to achieve perfection because you never will The lens you shoot with the lighting color and the sensor you use will in all likelihood have a color mixing function that precludes exact duplication of the numbers that result in measuring the color patches with a spectrophotometer Due to metamerism the colors of the patches may be un reproducible to a precise degree with your camera This same limitation is apparent when trying to make accurate color profiles of digital cameras and is what lead Thomas to devise his own scheme for making raw conversions The design is intended for visual adjustment not by the numbers
