Hi Grandpaw, here is something I discovered today. To the best of my knowledge it is not dealt with in any D7000 literature. You may want to share it with the rest of the folk. It is a very handy feature.
I wanted to take Raw pictures only in selected cases, and fiddled with the FN button to try and achieve it. Next moment all my pictures on card 1 was duplicated - Jpeg as well as Raw. I do not want that. Raw takes up twice the space jpeg uses. I could not find a fix. After a lot of frustration I discovered that if you press the Qual button and simultaneously turn the rear dial you can set the card configuration. It shows in the bottom left corner of the top screen. My camera is now set to only duplicate in Raw when the FN button activates it, and then de-activates it.
