Told you I would be back with questions. Is the Nikon Capture software the only way to load "curves" to the Nikon D100 camera? So far the curves I have found refer to the use of the Nikon program. I downloaded Nikon Capture 4 but I have Photoshop CS (8) and don't, as far as I can see so far, need the Nikon software for any photo editing purpose. Before I pay $99 for the Nikon software (using the trial right now) I wondered if it is really needed and/or if it has any other unique properties that I can't live without. As always thanks for any input.
