In photography, shutter speed or exposure time is the length of time that the film or digital sensor inside the camera is exposed to light (that is, when...

A shutter can also be used to allow pulses of light to pass outwards, as seen in a movie projector or a signal lamp. A shutter of variable speed is used...

refers to a setting on cameras that allows the user to choose a specific shutter speed while the camera adjusts the aperture to ensure correct exposure. This...

The eponymous name "speed" came from the maximum speed of 1/1000 sec. that could be achieved with the focal plane shutter. The Speed Graphic was available...

shutter used a dial to set shutter speeds; the early dial-set versions were succeeded by the rim-set version in 1927, which moved the shutter speed control...

the photographer of a moving subject may deliberately combine a slow shutter speed with flash exposure in order to record motion blur of the ambient-lit...

flashes at any shutter speed, up to its minimum shutter speed of 1/80000 second. This is in contrast to mechanical or electronic rolling shutters that have...

The LOMO LC-A (Lomo Kompakt Automat) is a fixed lens, 35 mm film, leaf shutter, zone focus, and compact camera introduced in 1984. Its design is based...
