I'd like to propose a philosophical question regarding this...
I see the point of monitor and printer color management - getting results that you expect consistently. I feel that camera profiling is more about getting authentic colors that record the scene in a way that the final image can closely match the original scene. I also see camera profiling as a way of getting exposures from mutiple cameras to match.
But what I don't understand is, in the course of landscape photography, are we objective to that extent? I don't know about you folks, but I rather enjoy interpretive color and tone adjustment to bring out a mood or my impression of the original rather than a rigid reading of the original. I feel more like creating than recording. I contemplate this from the very start, even before I set up the shot. For me, it is about what can I do with this raw scene to render it that way I imagine.
Given that subjective approach, what would I get out of camera profiling?
