Dawn, there's photography, then there's Photography. Learn as much as you can about the various processes that can go into making a photo so you will be able to talk with the photographers closer to their level of understanding.
Photography has always been technology driven, and what is going on today is considerably different from traditional and vintage processes. It is probably one of the most rapidly evolving art forms.
Learning techniques for holding the photo in place is important too. There are still a lot of photographers who have their pieces mounted (this is worthy of a thread of its own, so I won't belabor the point here), and that is their choice. All we can do is assume it is an informed one.
Since you say there's a lot of photography in your region, and you don't seem to be getting much if any framing out of it, what do you plan to do to change that? Most of what I see are images printed with an ink jet printer. They are treated much the same as I would a watercolor, and the matting and frame selection needn't be any different than that. When you get into more traditional and vintage photos is when you need to know what materials are appropriate for which technology.
