Abstract
Abstract A combined masking frame and photographic sheet material container comprises an elongated flat compartment for storing photographic sheet material and which has a side opening for removing sheets therefrom; the container has a top panel which has a rectangular recess therein having a planar light-reflecting surface and being of a shape to accomodate the sheets stored in the compartment. The container has hingedly attached thereto a lid which, in closed position, covers the top panel; the lid has along a front side an angular flange which when the lid is closed covers in a light-tight manner the side opening in the container, there being present in the lid a rectangular aperture of an area slightly smaller than the area of the recess so as to form a mask around the edge of a sheet in position in the recess. In a double container, a second compartment, lid and recess can be provided in upside down arrangement at the bottom of the first compartment, the side opening of the second compartment being located below the closed end wall of the first compartment and viceversa.
