There is a front opening which can be changed by inserting frames of different size openings into a slot above the opening. There is a rear opening adapted to permit the eye of the camera technician to look therethrough. A storage compartment is located below the viewing area for storing the various frames having different size openings. A handle assembly is located beneath the front lower portion to enable the technician to hold the viewer while he is looking through it to determine the frame size desired.
