I did this portrait session few years back. Actually so far back that I was still using one of my favorite cameras, a mamiya RZ 67 which is a medium format film camera suited to studio work. Compared to a 35mm camera it’s big and clunky but it really produced some nice images. We wanted to do some classic images and decided to shoot in a portable studio with a classic gray background. We got so many great pictures and so many expressions that we laid them out as a sequence and printed it as one large wall portrait and the final expression is shown enlarged on its own. The subject grew weary of the photographer by the end of the session. And of course the details.
