Hi again, I am a big Dave Black fan. His premise is to do EVERYTHING he can in camera humanly possible so he only has to pass his TIF or JPG to his editor. I adopt this philosophy as much as possible, but I am not bound by it. So, I believe it IS a question to ask in a forum dealing with settings and exposures. This set of circumstances might push the abilities of the camera, however. If there is a White Balance forum, it might go there, but I am interested in a magenta/green adjustment in the camera, if there is one.
