A Nikon-style mode dial showing aperture priority mode.. Aperture priority, often abbreviated A or Av (for aperture value) on a camera mode dial, is a mode on some cameras that allows the user to set a specific aperture value while the camera selects a shutter speed to match it that will result in proper exposure based on the lighting conditions as measured by the camera's light meter.
With the GE Synchro‑Press No. 11 for instance, a modern camera with a focal-plane shutter and X sync would require a shutter speed of 1 / 15 th of a second (67 ms) to obtain an even exposure across the entire image area—and a not-insignificant boost in the guide number by capturing all the luminous energy to the left of the 20 ms peak.
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 set EV could be locked, coupling shutter and aperture settings, such that adjusting either the shutter speed or aperture made a corresponding adjustment in the other to maintain a constant exposure (Ray 2000, 318). On some lenses the locking was optional, so that the photographer could choose the preferred method of working depending on the ...
