Manual modes: Manual (M), Program (P), Shutter priority (S), Aperture priority (A). Automatic modes: Auto, Action, Portrait, Night Portrait, Landscape, Macro. A dial with more modes. Most digital cameras support the ability to choose among a number of configurations, or modes for use in various situations.
ISO settings like 102,400 can yield guide numbers in excess of 1220 (m) / 4000 (ft) that seldom if ever permit extremely long-range flash photography due to particulates and aerosols typically present in outside air that fog images with haze glare and attenuate the reach of the light. Except in unusual atmospheric conditions, extraordinarily ...
Video demonstration of high-speed flash photography. A flash is a device used in photography that produces a brief burst of light (lasting around 1 ⁄ 200 of a second) at a color temperature of about 5500 K [1] [citation needed] to help illuminate a scene. The main purpose of a flash is to illuminate a dark scene.
In photography, exposure value (EV) is a number that represents a combination of a camera 's shutter speed and f-number, such that all combinations that yield the same exposure have the same EV (for any fixed scene luminance). Exposure value is also used to indicate an interval on the photographic exposure scale, with a difference of 1 EV ...
In photography, flash synchronization or flash sync is the synchronizing the firing of a photographic flash with the opening of the shutter admitting light to photographic film or electronic image sensor. PC-socket. In cameras with mechanical (clockwork) shutters synchronization is supported by an electrical contact within the shutter mechanism ...
Through-the-lens metering. In photography, through-the-lens metering (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 some cameras various TTL metering modes can be selected.
Digital photography spans a wide range of applications with a long history. Much of the technology originated in the space industry, where it pertains to highly customized, embedded systems combined with sophisticated remote telemetry. Any electronic image sensor can be digitized; this was achieved in 1951.
A Kodak dSLR with the mode dial located near the flash/viewfinder hump. A mode dial or camera dial is a dial used on digital cameras to change the camera's mode. Most digital cameras, including dSLR and SLR-like cameras, support modes, selectable either by a rotary dial or from a menu. On point-and-shoot cameras which support modes a range of ...
