Abstract: A method and apparatus for adapting photographic enlargers for use with various large format negatives are disclosed wherein a first large format negative stage is movably mounted relative to a lens stage of the enlarger for supporting a negative with its image focused upon suitable photographic paper or the like. A second large format negative stage is also placed at a selected spacing from the first large format negative stage by means of a suitable spacer to facilitate use of larger negatives, the spacer preferably being removable for permitting a single light source to be arranged closely adjacent to the second large format negative stage with the spacer in place and closely adjacent to the first large format negative stage with the spacer removed in order to achieve even, fully covered and optimum illumination.
