I have a portrait assignment coming up that I have to shoot. I live/go to school in the Upper Peninsula of Michigan so with the seasons changing I have to work with what available light I have since I don't have access to a studio. My main question/issue is that I'm going to be using my friends as models and I dont want to end up with "senior picture" looking images. My professor said we could do traditional or informal portraits, but since I've never really attempted this before, I was wondering if I should just go at it like I usually do when I capture my friends... without them knowing, but knowing.. You know what I mean? The class is a color class using slide film, so any help or suggestions or sites I could check out (I've already hit the library) would be awesome. Thanks!
