CS 4/5 Raw camera calibration

->> Does anyone that shoots in RAW (especially with a Nikon D3) notice a difference
when using the camera calibration settings in CS4 or CS5 rather than just using the default?
I have been using the D3 for several years as my primary camera and I really can't say I see a shift towards any color..Not like the old D100 which had a horrible magenta tint.

->> What you are seeing is likely the difference in the Process Version being applied under the hood by ACR ...

PSCS4, uses ACR v5.6 which applies default Process Version 2003. ... With ACR v6.x in PSCS5, the new Process Version 2010 was introduced, and I think the canned Camera Calibration profiles that ship with ACR also received some tweaks/updates as well ... so yes, you could likely be seeing some differences between the two versions of PS.

Wait, there's more ... when PSCS6 and Lr4 hit the market, there will even be a newer more improved Process Version 20102 ... ;-)

Adobe has been hard at work improving the image quality of ACR so we will likely continue to see this evolution in PV as time goes on.

->> If you want a calibration specific to your particular camera, get the ColoChecker Passport. Go through the simple setup and ACR will recognize your profile. It makes a noticeable difference from the canned ACR profile. The blues on my D3 are distinctly better.

->> While I would not want to encourage the purchase of the ColorChecker Passport ... there is also a very good free option for creating camera-specific Custom Calibration Profiles for ACR/Lr ... if you already own a ColorChecker target, Adobe Labs offers the free DNG Profile Editor.

Simply shoot the target in even light with the camera of choice, convert that image file to DNG, bring it into the DNG Profile Editor and the app can run an automatic script to export the profile which can be used in ACR/Lr. Please note that you do not need to convert all your images to DNG to use the profiles, only those images used to create the specific profiles.

I do have a concern with using the Passport package in the manner some have recommended. Some believe you should use the PP kit on EVERY shoot and create profiles for EVERY set of images you capture under a specific lighting situation. The big problem with this, I for one, would end up having several thousand different profiles created over a period of years ... and as long as you keep the images on hand that use the profiles, you also must keep the profiles for ACR/Lr to use in rendering the images.

I have found that using the basic dual illumination profiles that the Adobe software creates, goes a long way to simplify WB adjustments and render more accurate colors for the vast majority of images on it's own. YMMV.

I meant to say ... While I would not wand to discourage the purchase of ColorChecker Passport ..."

It really is a fine tool ...
