In optics, an aperture is a hole or an opening through which light travels.
Cactus is a brand owned by Harvest One Limited, a Hong Kong company specialized in the design and engineering of photographic wireless lighting equipment including wireless flash triggers, wireless flashes, portable softboxes and studio umbrellas.
A camera is an optical instrument for recording or capturing images, which may be stored locally, transmitted to another location, or both.
Carl Braun Camera-Werk of Nuremberg, Germany, or Braun, as it was more commonly called, was founded as an optical production house.
Clockwork refers to the inner workings of either mechanical machines clocks (where it is also called a movement) or other mechanisms that works similarly, with a complex series of gears.
In optics, particularly as it relates to film and photography, the optical phenomenon known as depth of field (DOF), is the distance about the Plane of Focus (POF) where objects appear acceptably sharp in an image.
A digital camera or digicam is a camera that captures photographs in digital memory.
A digital single-lens reflex camera (also called digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film.
An electrical contact is an electrical circuit component found in electrical switches, relays, connectors and circuit breakers.
Electricity is the set of physical phenomena associated with the presence and motion of electric charge.
The Exakta was a camera produced by the Ihagee Kamerawerk in Dresden, Germany, founded as the Industrie und Handels-Gesellschaft mbH, in 1912.
Fill flash is a photographic technique used to brighten deep shadow areas, typically outdoors on sunny days, though the technique is useful any time the background is significantly brighter than the subject of the photograph, particularly in backlit subjects.
A flash is a device used in photography producing a flash of artificial light (typically 1/1000 to 1/200 of a second) at a color temperature of about 5500 K to help illuminate a scene.
In camera design, a focal-plane shutter (FPS) is a type of photographic shutter that is positioned immediately in front of the focal plane of the camera, that is, right in front of the photographic film or image sensor.
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.
Canon EOS 350D Hot shoe Proprietary hot shoe used by Minolta and older Sony cameras (Konica Minolta Maxxum 7D) A hot shoe is a mounting point on the top of a camera to attach a flash unit and other compatible accessories.
An image sensor or imaging sensor is a sensor that detects and conveys the information that constitutes an image.
Motion blur is the apparent streaking of moving objects in a photograph or a sequence of frames, such as a film or animation.
The D40 is a now-discontinued Nikon F-mount entry-level digital SLR, announced November 16, 2006.
The Nikon F camera, introduced in April 1959, was Nikon's first SLR camera.
The Olympus OM-4 is an interchangeable-lens, 35 mm film, single lens reflex (SLR) camera; manufactured by Olympus Optical Co., Ltd.
Optics is the branch of physics which involves the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it.
Photographic film is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals.
The PocketWizard is a wireless radio triggering system for off-camera lighting developed in the late 1990s, by LPA Design, an American company based in South Burlington, Vermont.
A Prontor-Compur connection (also known as a PC connector, PC terminal, or PC socket) is a standard 3.5 mm (1/8") electrical connector (as defined in ISO 519, (1992-11-25). Photography -- Hand-held cameras -- Flash-connector dimensions. Geneva: International Organization for Standardization.) used in photography to synchronize the shutter to the flash.
Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width.
In radio communications, a radio receiver (receiver or simply radio) is an electronic device that receives radio waves and converts the information carried by them to a usable form.
In electronics, a remote control or clicker is a component of an electronic device used to operate the device from a distance, usually wirelessly.
In photography, a shutter is a device that allows light to pass for a determined period, exposing photographic film or a light-sensitive electronic sensor to light in order to capture a permanent image of a scene.
In photography, shutter speed or exposure time is the length of time when the film or digital sensor inside the camera is exposed to light, also when a camera's shutter is open when taking a photograph.
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.
In electronics and telecommunications, a transmitter or radio transmitter is an electronic device which produces radio waves with an antenna.
Xenon is a chemical element with symbol Xe and atomic number 54.
