The shutter speed dial of a Nikkormat EL Slow shutter speed combined with panning the camera can achieve a motion blur for moving objects. 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 the camera's shutter is open) when taking a ...
Shutter priority or time value. Automatic exposure mode where the photographer sets a shutter speed, and the AE firmware automatically sets the appropriate lens aperture. [4] SC: Soft Capture. Capture of light emitting objects as the primary subject with light quality that is not primary but equally soft or washed as the background. [citation ...
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 to control exposure time of the film. The shutter is constructed so that it automatically closes after a certain required time interval.
For example, as of 2008, Nikon cameras allow one to set the maximum and minimum ISO sensitivities, and slowest shutter speed that will be used in automatic modes, [4] while Canon cameras will select within the fixed range of ISO 400–ISO 800 in Auto ISO mode. In Nikon cameras, the Auto ISO mode first adjusts the shutter speed, keeping ISO at ...
For example, the photographer may prefer to make his sunny-16 shot at an aperture of f /5.6 (to obtain a shallow depth of field). As f /5.6 is 3 stops "faster" than f /16, with each stop meaning double the amount of light, a new shutter speed of (1/125)/(2·2·2) = 1/1000 s is needed. Once the photographer has determined the exposure, aperture ...
Popular exposure chart type, showing exposure values EV (red lines) as combinations of aperture and shutter speed values. The green lines are sample program lines, by which a digital camera automatically selects both the shutter speed and the aperture for given exposure value (brightness of light), when set to Program mode (P). (Canon, n.d.)
For example, at a focal length of 125 mm on a 35 mm camera, vibration or camera shake could affect sharpness if the shutter speed is slower than 1 ⁄ 125 second. As a result of the 2-to-4.5-stops slower shutter speeds allowed by IS, an image taken at 1 ⁄ 125 second speed with an ordinary lens could be taken at 1 ⁄ 15 or 1 ⁄ 8 second with ...
These AE SLRs were only semi-automatic. With shutter-priority control, the camera would set the lens aperture after the photographer chose a shutter speed to freeze or blur motion. With aperture-priority control, the camera would set the shutter speed after the photographer chose a lens aperture f-stop to control depth of field (focus).
