Hi, I have a similar problem with my old canon eos-300d in dt. The higher Iso images suffer a green cast. The problem is caused by the raw black levels being incorrect. For some reason dt sets the levels to high. May be your nikon problem is related. Try checking the raw black levels for the green images in dt and use Image-ExifTool to check what the values should be.
