Abstract: A drum processor insert for use in the drum of a photographic drum processor is described which enables the capacity of the processor to be substantially increased. The insert comprises a plurality of arcuate holders each adapted to hold a sheet of photographically sensitized material, and a frame, each holder being rotatably mounted on the frame so that it is swingable about an axis, parallel to the edges of the arcuate holder, from a closed position in which the frame and holders constitute a substantially cylindrical shape which fits in the drum with the edges of the holders at the periphery of the drum, and an open position in which a sheet of photographically sensitized material can be loaded into or unloaded from each holder.
