Type 55 Polaroid. Horseman 45HD with a zone plate mounted to the lensboard. Approximately 90mm zone plate to film plane. This is a favorite location to try the experiments. I did not use any of the camera's movements to keep it square, I don't recall why. : The Polaroid type 55 negs are slightly larger than a 'normal' 4x5 sheet, thus my scanner template doesn't fully get the edges.
