Jim, I had a few minutes to read a PDF on the subject. Seems like a strange naming convention, but the d-1 thru d-4 numbers are presets a user can save on a D4. There is a place to label the various presets, and a way to call them up by using the dials on the camera. I now need to actually set a couple of them to offset green.
I will also look over the fluorescent settings. That might be easier, too.
