A half-frame camera is a camera using a film format at half the intended exposure format. A common variety is the 18x24mm format on regular 135 film. It is the normal exposure format on 35mm movie cameras. For still cameras using the 35mm film, the usual format is 24x36mm, so still cameras taking 18x24mm exposures are called half-frame cameras.
