# Declaring cameras: <camera>

Possible embedded elements:

<maker>string</maker>
  Camera maker. This must be specified exactly as it is specified in camera EXIF data to allow for automatic recognition of the camera.
<model>string</model>
  Camera model. This must be specified exactly as it is specified in camera EXIF data to allow for automatic recognition of the camera.
<variant>string</variant>
  Camera variant. Sometimes makers create several cameras without changing EXIF information. Unfortunately, camera variant cannot be automatically detected so this is a manual choice item.
<mount>string</mount>
  Camera mount. There can be only one such element in camera declaration. If you want to specify that it is possible to use lenses with a different mount on this camera, use the <compat> element in mount declaration.
<cropfactor>number</cropfactor>
  Camera crop factor. This is the ratio between the standard film frame diagonal (36x24mm) and camera sensor diagonal.
