  <title>Image capture</title>

  <p>
    While the shutter can always be physically triggered on the camera, it
    is also possible to electronically trigger it from <app>Entangle</app>.
    Electronic triggering is available from the <guiseq><gui>Camera</gui><gui>Capture</gui></guiseq>
    menu option, the <gui>Capture</gui> icon on the tool bar, or the <key>Spacebar</key> key.
    After the shutter is triggered, any successfully captured images will be
    automatically downloaded and displayed. They are saved to the local session
    directory, as describing in the <link xref="image-storage"/> section. Some
    cameras supported capturing in multiple formats at once, for example, both
    raw and jpeg. If this feature is active, all image formats will be downloaded
    after capture.
  </p>

  <p>
    The camera's autofocus mechanism will be activated prior to capturing the
    image, and if it is unable to achieve focus an error will be displayed. If the
    camera is in live view mode, however, no autofocus will attempted. Consult the
    <link xref="camera-focusing"/> section for details on how to control focusing
    manually.
