I should have added, I use a ColorChecker Passport camera profile.
The tint slider will affect the whole image. What would be nice in C1 color editor, would be if, when selecting a colour and then selecting display of just that colour in the whole image, we could make that, in PS terms, a selection, then make that selection into a new adjustment layer, then fiddle with tint etc just in that layer.
Jeff, it might be interesting to see results from sensors with, say, 1.5, 1.75, 2.0, 2.25, 2.5 times as many green receptors as red & blue.
