I'm currently looking for an event photographer for my upcoming wedding. It seems that most photographers do not want to release any images that they haven't touched up or edited. On the other hand, this seems to be standard practice for videographers: they deliver an edited movie as well as all of the raw footage that they shot. I'd rather not just let the photographer pick the X images that he/she thinks are best to edit and deliver because he/she won't have the same opinion as me as to which images are the best.
Why don't photographers want to give up any images that they haven't edited?
