While I am familiar with the strategies and techniques for using curves to "correct" color in an image, I would like to get even more "objective" color accuracy with RAW images.
I want to shoot a perfect image of a Color Checker (using a handheld light meter for calculation of the precise incident exposure under highly clontrolled and repeatable studio lighting conditions), run it through ACR, and the apply software (like Gretag Macbeth Profile Maker) to create a profile that can be applied for all shots taken under identical lighting circumstances. Exact representational color accuracy is critical for the these images.
Unfortunately, the adjustment tabs for exposure, brightness and contrast are completely arbitrary and seemingly MUST be applied to the image before getting it into CS2. I am completely unclear on what "neutral settings" are. "25" for brightness?? "50" for contrast?? How do I get the CC image out of ACR with minimal alteration while maintaining the perfect lighting for the exposure so it can be accurately and appropriately analyzed by a profiling software? If the target image is altered, then the resulting software analysis and subequent profile are rendered useless.
I need to know what "ground zero" is for ACR adjustment settings. Thanks for your help.
