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 ...
Long-exposure, time-exposure, or slow-shutter photography involves using a long-duration shutter speed to sharply capture the stationary elements of images while blurring, smearing, or obscuring the moving elements. Long-exposure photography captures one element that conventional photography does not: an extended period of time.
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.

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 ...
Slow shutter speed (long exposure time) of a breaking wave 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 ).
A Nikon-style mode dial showing shutter priority mode. Shutter priority (usually denoted as S on the mode dial), also called time value (abbreviated as Tv ), 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 .
The life-expectancy of a mechanical shutter is often expressed as a number of shutter cycles. Most digital cameras save the shutter cycle information along with the photos, which contains valuable information such as shutter speed, aperture, and shutter count. [12] There are multiple websites and applications to access the EXIF data.
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 / ...
