Depends on what you're doing. You can at least adjust levels or curves in 16
bit mode which is the big area where you're going to lose colours. I suppose
in the grading you'd have to look at the effect and maybe find out what they
did (and in what order) and determine if the problem was with their
technique (such as adjusting levels in 8 bit mode when they started with a
16 bit source) or with the technology (the banding was a result of an
operation that discards colours but that can't be performed in 16 bit mode).
With the editing I do (clean dust, adjust the levels, apply slight
sharpening), I don't end up with any banding. But they're probably doing
more involved editing.
