Color Correction vs. Color Enhancement
I've been having some interesting discussion about this in regards to my post, Color Correction.
"Color Correction" is one thing, basically what I described - finding a reference within the scene and then matching the rest of the material to it. "Color Enhancement" on the other hand, is the work usually done in the DI Suite. This term should refer to "improving the aesthetics of an image, establishing stylized looks, and setting the mood of a scene through color" (from wikipedia). In my mind it's very important to draw the distinction between the two as they are potentially different services, may require different working conditions and time commitment, and are ultimately different skill levels - one very technical, the other creative.
It's interesting because the film, Oh Brother Where Art Thou?, is still the poster child for Color Enhancement. To me, it's probably one of the least photographic (that is, the most effected) mainstream motion pictures ever made. Not that it's a bad thing but I think it's important to recognize the difference.
