Dear Thomas, I have great curiosity about this info. Is this just so simple? If so, what is the use or rationale to include all other color patches in the card ( 24 in total)? I find that if I set ( in Levels) the White point first ( at a value of , say 245 instead of 255) and followed by the Black POint ( set at 10 or 15) then there is no way I can have the Grey point to fall in the Expected 128 target value. THis is odd to me and still have no defined workaround for this, specially since it has happened on some ocasions that the order of the color sampling( Black first of Grey first) introduces changes in the overall values. Do you have a formal, foolprof way to set a standard calibration with this Color Card Checker ( by GretagMacbeth)?? I will really thank you for being as detailed as possible in your explanation. I have been working with the card for sometime, and even though it has helped me somehow, still there are some "holes" in the behaviour of it ( at least when using a Canon D60). Checking the Color values (Info Pallette in PS7) of the Card's Patches introduces the obvious need to run a full set of Selective Color adjustments to get close to their target values, so a simple Black/ White and Grey Points is not good enough according to my tests. It follows then that files shot in same conditions should also be loaded with all those adjustments. I will appreciate your comments. I keep running tests with this card and include it in every shooting I do, along with Custom White Balance for each lighting situation.
