In the camera used, a Rolleiflex Automat MX TLR, the film moves vertically through the camera. Any edge fogging of the roll would be on the left and right side of the images and would be along the entire roll of film.I'm wondering what caused the darkening at the sides. It isn't parallel to the edges of the film and looks sort of like vignetting, but the film couldn't have been aware of where the exposed frames would be. And why are the images so unsharp, or is it just a matter of low contrast?
