I have a buddy that I'm gonna ask to see if I can take some pics of him before he leaves town to do his competition and I have no idea what to use. I'm going to assume that I will have to rent all of my equipment but what I have is an xsi with a macro, wide angle, telephoto and the normal lens that came with the kit. All my lenses are for the beginner so not exceptional quality. I have a local camera shop that I can rent lenses as well as lighting. I will be using a couple of white sheets for background and was wondering what I should rent as far as lighting and lens. Keep in mind I'm asking him so this is more for me than anything.
