Shutter button

 ( Camera Features ) 

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.

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 may be automatic). Some cameras also utilize an electronic shutter, as opposed to a mechanical shutter.

The shutter-release button is one of the most basic features of a dedicated handheld camera. Mobile devices such as modern have a touchscreen button for capturing photos, but also have a physical shutter button as well, as the sound volume buttons are used as such, with exception of some phones having a dedicated shutter button.

The term "release" comes from old mechanical shutters that were "cocked" or "tensioned" by one lever, and then "released" by another.

In modern or digital photography, this notion is less meaningful, so the term "shutter button" or simply "capture button" is more used.
