Yesterday I practiced taking head shots of a friend. It took at least 50 photos before she relaxed in natural poses, and we wound up with about 300 photos in the end. I used my 100mm Macro lens for the photos, which makes for much crisper photos than my 17-55mm kit lens. Of course the slight inconvenience with 100mm telephoto is having to scoot way back just to fit her head in the shot. We used natural light as well as flash, bounced off the ceiling.
