- n. In photography, a movable frame fitted to a camera, used to contain and transport a sensitized plate, which is exposed to the image projected by the lens by withdrawing a slide or shutter after the holder is in position in the camera; a dark-slide; a plate-frame. The plate-holders for dry plates are usually made double, for economy of space, and, after exposure of the plate in one side, are reversed in the camera in order to expose the plate in the other side.
- n. A pneumatic device for holding a photographic plate during development or other manipulation.
