So, uh, idk what anyone else is talking about but Columbia College is well known for their Photography program in particular. Dawoud Bey is the head of their department right now, IIRC? Also, personally, I think choosing CC looks a little more "with it" on a resume; like everybody knows RISD is good, but Columbia College looks special. Going to a lesser-known yet known-for-being-fantastic program vs. one everybody applies to by default? I'm not sure if I'm making sense, and maybe this doesn't matter to anybody else.
As a photographer I'd have no reservations choosing Columbia College here, personally. I think, however, RISD leans toward a very technological direction and has been doing this techie/green/science slant lately so if that's what you do then you're going to get a lot of great support to do that.
