   As a photo hobbyist, I prefer to shoot raw then work the files later.  This saves me a lot of trouble setting up the camera while I am shooting.  Generally I shoot at least 7 shots to get one worth keeping.  For the rare worthwhile shot, I like to spend time fine-tuning and enhancing the image to get rendering the way I like it.
