A flash that coordinates with the camera's exposure, and sometimes focusing systems. Dedicated flashes may, among other things, automatically pick up the loaded film's ISO, set the camera shutter speed to X-sync, and "tell" the camera when its ready to fire. Flashes dedicated to autofocusing cameras may also vary their angle of flash throw according to the lens in use (even with zoom lenses), and contain autofocus beams that aid focusing in very dim light or even total darkness. For outdoor work, dedicated flashes may provide totally automatic fill-flash exposure. In short, a dedicated flash can be make flash photography as simple as automated natural light photography.
Electronic flash that must be used with specific cameras to automatically adjust the camera's exposure controls to produce the correct exposure.
A flashgun designed for use with a specific camera. It links directly with the internal camera circuitry to help produce perfectly exposed photos.
a flash unit that is electrically connected (though not neccessarily mounted in) the camera's hot shoe
Electronic flash designed to work with the meter and exposure system of a specific camera.
A flash that is specifically designed to operate with a specific camera. When using a dedicated flash, the camera communicates with the flash to allow the user to use automatic exposure modes. (See TTL)
An electronic flash that is designed for specific camera makes and models. When the flash is attached to the camera and turned on, the camera's shutter speed is automatically adjusted to the correct setting. Normally with dedicated flashes other functions have also been automated.
An electronic flash unit that integrates automatically with a specific camera's exposure meter and exposure controls, permitting simplified, fully-automatic use of the flash. A dedicated flash is designed to work with a particular brand or type of camera.
A fully automatic flash that works only with specific cameras. Dedicated flash units automatically set the proper flash sync speed and lens aperture, and electronic sensors within the camera automatically control exposure by regulating the amount of light from the flash.
flash gun designed to integrate automatically into a cameras exposure reading and shutter circuitry.
