Table-top macro background holder

Many times it becomes necessary to use a card or other two-dimensional material as a background or light modifier for small scale table top photography.

Mounting these materials has been a previous challenge. The use of “A” spring-type clamps, wooden blocks and other mounting schemes is only somewhat successful. As illustrated below, some of these devices may get in the way on the table top.

The solution that really works is an adjustable clamp that will hold a variety of cards, plate glass or other materials vertically and securely. These adjustable clamps are very simple and easy to construct out of common, low-cost materials.

In use, these clamps allow the easy, yet secure, positioning of light modifiers such as glass, scrims, flags, reflector boards, and background cards or prints. They also require little space on the table top so they don’t interfere with positioning of the subject or other props.

MATERIALS :
(All dimensions, inches.)
1 ea-  1/2 X 1 1/2 X 12 clear lumber
2 ea-  3/4 X 1 1/2 X 12 clear lumber
1 ea-  1/2 X 1 1/2 X 12 clear lumber
1 ea-  3/8 X 4 inch coarse thread (all thread) carriage bolt
1 ea-  3/8 coarse thread recessed Tee nut.

CONSTRUCTION:
Assembly of the holder is straight forward. Measure and cut all wooden stock to size. Drill a hole through one piece of the 3/4 inch stock at its center and mount the Tee nut as shown below. Screw and glue the two larger pieces to the base as illustrated. Insert the carriage bolt into the side piece to secure the smaller clamping board. In use, simple finger pressure is sufficient. Position the bolt side of the assembly away from the camera on the table.

My specifications suggest 12 inch long materials. Background holders of other dimensions may be desired depending on the required use.
