Edward, Judy and Mike,
Thank you, all, for sharing this (above). I am not sure of some of the valuable suggestions which Judy spoke about.
(" shooting in raw and editing in tff format to maximize the results. Editing in jpg will result in a certain amount of compression. I have found that some of the editing programs will not support tff files"). This is all new to me...but, surely, I want to be able to learn this technology.
