Process and Copy Cameras, Continued Copy cameras Copy cameras are similar to process cameras but smaller. Many copy cameras are simply small-format cameras (lens and focal plane) on stands with copyboards (copy plane) and adjustable light systems. Copy camera lenses Lenses for copy cameras are usually not interchangeable unless the camera used in the stand is a detachable small-format camera. Generally, copy camera lenses are 50mm in length with some lenses having super close-up (macro) capabilities. Copy camera film backs The camera back or film plane may house 35mm, 120mm, or instant-imaging film. The film type used in the film back may be negative- or positive- imaging or color or black-and-white film or paper. Copy camera adjustments Copy cameras adjust in the same way as small-format cameras. Load the film into the film back. Set the ISO and select a shutter speed and/or aperture. Copy camera exposure Copy cameras have a shutter-release button or a cable release connected to the shutter-release button. The cable release minimizes camera movement when the shutter is depressed. Figure 7-7 compares a shutter-release button with a cable release. Figure 7-7.—Shutter releases: A. Shutter-release button; B. Cable release. 7-13
