This strap goes over the shoulders of the person wearing it and supports one or more cameras hanging down in front of the body of the wearer. Portions of the strap that extend downward behind the shoulders converge toward one another and are connected with a stretchable or elastic part of the strap which has its lower end anchored to a trouser band or belt, and which prevents the converging parts of the strap from moving upward into contact with the back of the neck of the person wearing the strap. Thus the weight of the cameras never bears against the neck. The stretchable part of the back portion of the strap yields when the wearer bends forward, and this prevents uncomfortable tightening of the strap.

Camera supporting strap

This easel for photographic enlarging has retainers for holding paper in position on the easel, and improved means for adjusting the retainers for paper sheets of different size. There are clamps for holding the retainers in set positions and provision for preventing parts of the clamps from becoming disconnected when turned in directions to release them. A single clamping screw for each retainer expedites adjustment. Masks for paper of different size have the same spacing of screw-receiving openings corresponding to a single standardized spacing of threaded openings in the easel plate.

Adjustable enlarging easel

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.
