I have about $100 in giftcards to Amazon from the holidays, so I am considering getting a ColorChecker Passport. My question is, how well does profiling your camera really work. Getting accurate color (on profiled monitors) hasn't exactly been my strong suit. And I would like to be able to get there for some studio, portrait and even landscape shots. I know accurate isn't always pleasing, but I feel it would give you a good start to put a "look" on top of, ala the motion picture industry.
Also, if you do profile your camera, do you need to do it with each lens, or just once per camera?
I'm working with a Nikon D7000, Fuji X10, and Yashicamat EM (Trying Portra at the minute, but thinking I prefer slide films to negatives) in Adobe PS CS5. Even more cameras if I decide to profile the ones at work.
I'm also just starting Schewe's book on RAW processing. (Which made me wonder what motorcycle he rides...)
