I've now added a D2x to my D100 on a permanent basis. I've rented D1x, SLR/n, D100, D70, etc before on an as-needed basis, and found that shooting with multiple bodies even of the same type often required some degree of additional post-shoot processing that was about trying to get the two cameras' color profiles to be perfectly in sync. No big surprise, I guess, since there will always be some degree of variation around a midpoint. I run multiple editing and processing systems since recent events have had me adding someone to do some of my post processing. By using profiling software and hardware, I can get perfect consistency - or at least consistency perfect enough that two prints side by side in a light booth can not be distinguished. Not true of cameras. Is anyone profiling multiple cameras in the same way? I could see how shooting multiple bodies for a two or three day gig could add hours if not days of little tweaky editing stuff. Is it possible to nail down profiles like that with cameras? Or is it all just go back to grey card/color chart shooting and clicking? I do that, but it's clearly not adequate - I shoot a fair amount of documentary stuff, like a three day recording session where each musician is in light that may require different white balancing, or you're shooting live concert stuff where the light person is getting whacky with exotic color changes. The only way I see out of this is camera profiling, but I can't find a ton of info to suggest it's really doable, and productive. Much obliged.
