Going to take some pictures of a friend tomorrow with really pretty eyes. The shots are gonna be focused on the eyes, many up them probably close-up, even "eye only" pictures. I'm wondering what settings i should start with(I will play around some with them but just want to have a starting point) Should I try to do it outside if its descently sunny? Or just have sufficient light inside, cause I'm guessing I'm not gonna want to use a flash...? Anyway, any help would be much appreciated
