A shutter that opens and closes near to the film or image sensor, usually as a fast-moving slit, as contrasted with a bladed/leaf shutter located near a nodal point of a lens. [12] FPA: Focal plane array. A matrix of sensors positioned in the focal plane of a lens or other focusing device. [12] FPS: Frames per second. Used in reference to ...
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 ...
A or Av: Aperture priority or Aperture value enables manual control of the aperture, and shutter speed is calculated by the camera for proper exposure (given an ISO sensitivity). S or Tv: Shutter priority or Time value enables manual control of the shutter speed, and aperture is calculated by the camera for proper exposure (given an ISO ...
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.)
An approximately correct exposure will be obtained on a sunny day using ISO 100 film, an aperture of f /16 and a shutter speed of 1/100 of a second. This is called the sunny 16 rule: at an aperture of f /16 on a sunny day, a suitable shutter speed will be one over the film speed (or closest equivalent).
On a sunny day at ISO 100 ("100 speed film"), the aperture is set to f /16 and the shutter speed (i.e. exposure time) to 1 / 100 or 1 / 125 [2] seconds (on some cameras 1 / 125 second is the closest available setting to 1 / 100 second). On a sunny day at ISO 200 and aperture at f /16, set shutter speed to 1 / ...
In photography, shutter speed is a common term used to discuss exposure time, the effective length of time a camera's shutter is open. Slower shutter speeds are often selected to suggest movement in a still photograph of a moving subject. Fast shutter speeds freeze a moving subject on photograph. Reason
Another common use of aperture priority mode is to indirectly affect shutter speed for a desired effect. In landscape photography, a user might select a small aperture when photographing a waterfall, so that the camera will select a slow shutter speed (to allow a sufficient amount of light to reach the film or sensor for proper exposure), thereby causing the water to blur through the frame.
