Abstract
This easel holds photographic paper in position for exposure during an enlarging operation. The paper is placed on a plate and pushed up against a shoulder at one end of the plate; after which a masking frame is swung down into contact with the paper to hold it flat. Retaining elements extending from the shoulder hold the paper flat on the plate and prevent it from curving upward along the shoulder where the paper could be bent and creased when the masking frame swings down into contact with the paper.
