Exhibition shots I've seen usually show them contact printed at 11x14". He has an old studio camera, Kodak or Century I think, and I think he's used mostly one not terribly unusual lens, and I suspect the film isn't anything surprising either, since there aren't so many options in color. His lighting is simple--like an umbrella or large parabolic umbrella for the main and one for fill and a background light or two, but he has lots of power. As I see it, his style puts the main emphasis on interaction with the subject, and the big studio camera is part of that interaction.
