A number of surface irregularities (3a-3h) are provided on the inner surface (2) of the cylindrical vessel mantle (1) so that the photographic sheet (7) exposed to an image is raised clear from the mantle surface, leaving a gap (9) in between the mantle and sheet. The vessel has a removable cover at one end and contains a developing/fixing medium (8). |
