Dear Bill,
With regard to the camera making choices....
The more time you spend with a digital camera (as with transparency film) the more you find that you drive it to where you want. An organic internalization occurs and you find the sweet spots. Bracketing the h3ll out of it helps when things are less obvious.
I always shot slide film. So no real post even with the limited choices available in the dye-transfer/C/M etc process.... Only no, no, no, yes, no, no, no.... Selection is the edit, not manipulation.
I think with digital there may be the phenomenon where people change cameras too fast, never really finding the sweet spots as they would have had they stuck with a camera and really learned, not just the obvious technical points, but how to really drive it to where it worked for them. Just like learning how to use slide film and have the colours sing without being mud or cartoonish.
Black and white digital? All bets off, señor. Better get your tools in order if you want a good B&W print from digital.
