ABSTRACT:
A photographic enlarging apparatus includes an easel having a flat platform with an upstanding wall along a top edge. A carrier for supporting photographic paper is slidably supported on the platform and is placed in contact with a vertical guide surface on the upstanding wall to appropriately orient the carrier on the platform. The carrier includes a generally rectangular frame with a paper support panel mounted within the frame to support a sheet of photographic paper on either the upper surface or the lower surface. The outer peripheral surface of the frame has a plurality of upper indexing apertures aligned longitudinally in the upper half of the outer surface, and a plurality of lower indexing apertures aligned along the lower half of the outer periphery. An indexing pin projecting from the guide surface on the upstanding wall cooperates with the indexing apertures such that the carrier may be indexed with respect to the easel in either an upright or inverted orientation, with either the upper panel surface or lower panel surface directed upwardly. A plurality of various size masking plates are mounted to the upper surface of the upstanding wall and cantilever outwardly over the easel platform and parallel therewith, such that the paper carrier will slide easily between the masking plates and the platform.
