Aperture priority, often abbreviated A or Av (for aperture value) on a camera mode dial, is a setting on some cameras that allows the user to set a specific aperture value (f-number) while the camera selects a shutter speed to match it that will result in proper exposure based on the lighting conditions as measured by the camera's light meter.
An autofocus (or AF) optical system uses a sensor, a control system and a motor to focus on an automatically or manually selected point or area.
The Bulb setting (abbreviated B) on camera shutters is a momentary-action mode that holds shutters open for as long as a photographer depresses the shutter-release button.
DX (Digital indeX) encoding is an ANSI and I3A standard, originally introduced by Kodak in March 1983, for marking 135 and APS photographic film and film cartridges.
When setting photoflash exposures, the guide number (GN) of photoflash devices (flashbulbs and electronic devices known as "studio strobes", "on-camera flashes", "electronic flashes", "flashes", and "speedlights")The Nikon brand name for its camera-mounted electronic flash products, Speedlight, is frequently used in lowercase form (speedlight&thinsp) as a generic term for hot shoe-mounted electronic flash devices.
(or), also known just as Nikon, is a Japanese multinational corporation headquartered in Tokyo, Japan, specializing in optics and imaging products.
The F55 (or N55 as it is known in the U.S.) is a 35mm film SLR autofocus camera introduced by Nikon in 2002.
The F60 (or N60 as it is known in the U.S.) is a 35mm film SLR camera which was sold by Nikon between 1998 and 2001.
Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures.
Shutter priority refers to a setting on some cameras that allows the user to choose a specific shutter speed while the camera adjusts the aperture to ensure correct exposure.
A single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system (hence "reflex" from the mirror's reflection) that permits the photographer to view through the lens and see exactly what will be captured.
In photography, through-the-lens (TTL) metering refers to a feature of cameras whereby the intensity of light reflected from the scene is measured through the lens; as opposed to using a separate metering window or external hand-held light meter.
135 is photographic film in a film format used for still photography.
