Re: Color shift is more troubling

I've been meaning to post my results but haven't gotten around to it. The banding is correctable but the color shifts on the D7100 shadows when pushed are not, at least not easily. theSuede says it's the result of of the green channel having to be pulled up a few ADUs above the other channels, whereas the Sony sensor doesn't have that problem.

Horshack, can you provide a link to theSuede's posting?  I can't seem to find his username in the forums, only your references to it.  I'm curious as to why this green pull was necessary.  It sounds like this is an amplitude=dependent RAW cook, but what I don't understand is why it doesn't cause an overall green color cast.  Perhaps that earlier posting about "green shadows" was on to something?

Sure, his post is here. It's specific to the shadows and Nikon's black clipping, which according to theSuede has to be perfect across the channels to avoid color casts in the deep shadows.
