What is shutter button?

Shutter Button

In photography the shutter-release button (sometimes just shutter release or shutter button) is a push-button found on many cameras, used to take a picture. 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.

Famous quotes containing the words button and/or shutter:

    What is the life of man! Is it not to shift from side to side?—from sorrow to sorrow?—to button up one cause of vexation!—and unbutton another!
    Laurence Sterne (1713–1768)

    And there is nothing in the eye,
    Shut shutter of the mineral man
    Who takes the fatherless dark to bed,
    The acid sky to the brain-pan;
    And calls the crows to peck his head.
    Allen Tate (1899–1979)
