Charlie - As an ex-Cambridge and Polaroid shooter, you might be interested in knowing that Elsa Dorfman still uses a Polaroid 20 x 24 monster for her famous portraits... I believe she bought all of Polaroids remaining stock of the film... 25+ years ago I had the chance to take an insider's tour of a special room at Polaroid in Cambridge... one with a motorized view camera built into the wall. I do not remember how large the format was but we are talking many feet by many feet with motorized/robotic film handling and camera controls. I believe this set up was used for then state of the art miniaturization of electronic components, and the scale of it was humbling. I remember the lens was a custom one-off from Zeiss which cost over six figures in 1980s dollars.
