Abstract
During processing of a photographic material, the non-sensitive surface of the material may become contaminated by the processing solutions used. Described herein is a support or carrier (10) which prevents such contamination of the non-sensitive surface. The carrier (10) comprises a series of parallel, upright blades (12a, 12b, . . . , 12q) separated by spacers (14a, 14b, . . . , 14q). Each blade (12a, 12b, . . . , 12q) has an upper edge (16a, 16b, . . . , 16q) which, when the carrier (10) is oriented horizontally, lies in a horizontal plane. The blades (12a, 12b, . . . , 12q) are sufficiently thick and rigid to support a sheet of photographic material lying on them without damage, the material being slightly larger than the carrier to prevent contact between the edges of the material and the carrier thereby avoiding transfer of any processing solution on the sensitive surface of the material to the non-sensitive surface thereof.
