has anyone ever taken an online photography course? i've been considering it. i would love to get a BFA in Photography, but i just dont have the time for anything but online, and i cant afford san fransisco's academy of art's $670 a UNIT. i've looked at a couple of "online photography courses", you know, the "non-degree-just-help-you-develop-your-art" kind of course, and i'm not totally convinced its worth the money. is it something i can gain from books alone or do you think the interaction and the courses really help that much?
