A film magazine for cameras which may be loaded with a long roll of film on the supply spool and which may wind the film into shorter length units into a cassette or the like on the take-up spool when desired for removal of the cassette from the magazine without exposing the film remaining on the supply spool. The magazine includes a container in which the supply spool and take-up spool is mounted and a second housing is fastened in the container and disposed about the take-up spool. A light trap in the second housing permits film to travel in the path from the supply spool to the take-up spool. A cover closes the container against the admission of light while film is disposed therein, and the cover has a port providing access into the second housing. A closure member may be selectively disposed within the port and may be secured to the housing to close the take-up spool from admission of light and to permit removal of the take-up spool without removing the cover. When less than a full long roll of film is expected to be used an empty cassette may be inserted onto the take-up spool and the leading edge of the film attached thereto, and after the desired number of frames are photographically exposed the closure member may be removed, the film in the second housing cut to permit removal of the cassette, and another cassette inserted therein.
