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...

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...

longer shutter speeds will only increase the contribution from continuous ambient light, which can lead to ghosting with moving subjects. Shutter speeds influence...
