A cassette is provided for manually transporting a sheet of photographic film from one station to another without exposing the film to ambient light. The cassette comprises a light-tight enclosure provided at one end with a pair of rollers and at the other end with a resilient light seal. The rollers are adapted to be rotated in response to engagement with driven rollers associated with one station for advancing a film sheet into the cassette. The film sheet is positioned within the enclosure with a lead end thereof protruding from the resilient light seal. The cassette is then carried to another station where the lead end of the film is adapted to be inserted into a pair of driven rollers associated with another station for withdrawing the film sheet from the cassette.
