ABSTRACT:
The hinged image holder of a photographic enlarger has its upper portion loosely attached to the lamp housing so that it is automatically opened for inserting and removing original images when the lamp housing is moved away from the rest of the enlarger. The lamp housing may be hinged or move parallel to the rest of the enlarger. The upper part of the holder is loosely attached to the lamp housing by variously shaped clips or slots which engage corresponding portions on the lamp housing.
