Camera Shader
Support for custom cameras, ray distortion maps and vignetting maps.
Exposure
Simulates the effect of camera exposure (in a non-physical way). Increasing this parameter by a value of one gives you one stop up (doubles the brightness).

Vertical Mapping
Activated when the camera Projection (In the View tab) is set to cylindrical. Also known as 'projective'.
The Arnold cylindrical camera can operate in two modes. With 'projective' set to off, all rays have a common origin - they are cast from the center of the cylinder. In the vertical direction the camera acts as a pinhole camera, and in the horizontal direction, it acts as a spherical camera. With 'projective' set to on, the camera is more of a true cylindrical camera; in the vertical direction the camera acts as an orthographic view, and in the horizontal direction it acts as a spherical camera.

Fisheye Camera
Is activated when the camera Projection (In the View tab) is set to Perspective. It is controlled by the Focal Length and Aperture in the View tab.
Fisheye Autocrop
Is activated when the camera Projection (In the View tab) is set to Perspective and Fisheye Camera is turned on.
Crops a full-screen image from the center of the fisheye image to remove any white border.
