Jill and I have a long-running conversation regarding posing for photos. I once told her to act natural, at which point she stared blankly at me because for her that would be natural :) She claims that when someone poses, it is in fact NOT natural but more of a performance of a character of sorts. Last night, I asked her to act natural and she grabbed the sides of the background and showed one eye, much to my delight!
Mamiya RB67 Pro S with 180mm lens and Polaroid back using Fuji 100 instant film. Handheld and sideways!(ouch).
PS. This instant film is outstanding.
