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 [smartphone](/source/smartphone)s have a [touchscreen](/source/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.<ref>
