The illustrated embodiment shows a film feeder for feeding individual film sheets to automatic developers. The film feeder has a magazine for receiving a stack of the film sheets, an extraction device and a transport device for transferring the individual film sheets extracted from the magazine into the automatic developer. The transport device contains an apparatus for selectively rotating the film sheets by approximately 45.degree. about their surface normal, and may be utilized with automatic developers which normally receive large-format films sheets, to enable the use of such developers with sheets of substantially shorter length dimension (e.g. 100 mm).
