I’ve ordered 12″x 12″ transparent gels. The gels are to be used as a color background in macro photography. They will be held by the 13.5″ square black frame. It snugly fits within the metal frame and the wood base, although I have clamps coming. The gel frame will be held to the table with the two blue clamps you see. Note the base’s curved corners to match the table. The wood finish is enhanced for better water protection.
I’m very pleased with the frame to hold transparent gels.
