The Bulb setting (abbreviated B) on camera shutters is a momentary-action mode that holds shutters open for as long as a photographer depresses the shutter-release button. The Bulb setting is distinct from shutter's Time (T) setting, which is an alternate-action mode where the shutter opens when the shutter-release button is pressed and ...
In photography, the shutter-release button (s just shutter release or shutter button) is a push-button found on many cameras, used to record photographs. [1] When pressed, the shutter of the camera is "released", so that it opens to capture a picture, and then closes, allowing an exposure time as determined by the shutter speed setting (which ...
Shutter priority refers to a shooting mode used in cameras. It allows the photographer to choose a shutter speed setting and allow the camera to decide the correct aperture. This is sometimes referred to as Shutter Speed Priority Auto Exposure, or TV (time value on Canon cameras) mode, S mode on Nikons and most other brands. [citation needed]
The shutter is constructed so that it automatically closes after a certain required time interval. The speed of the shutter is controlled either automatically by the camera based on the overall settings of the camera, manually through digital settings, or manually by a ring outside the camera on which various timings are marked.
A system for indicating correct exposure in which the shutter speed and f-number are related arithmetically. [4] [15] EVF: Electronic viewfinder. The through-the-lens view is displayed on a miniature solid-state screen, rather than on an optical screen or view. [2] EVIL: Electronic viewfinder interchangeable lens camera.
DEP: [3] DEP (DEPth of field) mode, on some Canon cameras, set the aperture to yield the desired depth of field: one point at the nearest object that one wants to be in focus, half-presses the shutter, then points at the farthest object that one wants to be in focus, half-presses the shutter, at which point the camera sets both focus and ...
The rule serves as a mnemonic for the camera settings obtained on a sunny day using the exposure value (EV) system. The basic rule is, "On a sunny day set aperture to f /16 and shutter speed to the [reciprocal of the] ISO film speed [or ISO setting] for a subject in direct sunlight." [1]
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 .
