Auto exposure exposure – Automatically determines an appropriate exposure value for the render. It requires Light Cache in Single frame mode to be set as the GI engine.

Auto white balance – Automatically determines a suitable white balance value for the image. It requires Light Cache in Single frame mode to be set as the GI engine.

Camera/view – Specifies which camera and/or views to use the automatic exposure and white balance setting.

All cameras/views
Views/cameras without exposure only

Transfer to Camera – (available only if Auto Exposure/Auto white balance is calculated) Lets you transfer the calculations to a selected camera as an ISO correction, keeping the options affecting Depth of Field and Motion Blur unchanged (e.g. shutter speed, f-number). If there is no selected camera, the Select from scene window opens to select a scene camera from the list. 

Type  – Specifies the type of the camera.

Default – Allows for the current scene camera to be used (usually a pinhole camera).
Orthographic – A camera enabling a non-perspective view similar to the standard Orthographic view in 3ds Max.
Perspective – Overrides the scene camera to force it to be a pinhole camera.
Spherical panorama  – A spherical camera with independent horizontal and vertical FOV selection that is useful for generating latlong images for spherical VR use.
Cube 6x1 – A variant of the Box camera with the cube sides arranged in a single row. Unlike the Box camera's output, Cube6x1 does not produce an empty space in the output image and is quite useful in generating cubic VR output.

Override FOV – When enabled, you can override the 3ds Max's FOV angle with the value entered. A possible reason for using this parameter is that some V-Ray camera types can take FOV ranges from 0 to 360 degrees, while the cameras in 3ds Max are limited to 180 degrees.

Vertical FOV – Specifies the field-of-view angle in a vertical direction. Replaces Cylinder height when using a Spherical panorama camera type.
