Linear Exposure Control samples the rendered image and uses the average
brightness of the scene to map physical values to RGB values. Linear Exposure
Control is best used for scenes with a fairly low dynamic range.
NOTE Linear Exposure Control should not be used in animations, because every
frame will have a different histogram, causing your animation to flicker.
IMPORTANT The mental ray renderer on page 6039 does not support the Linear
exposure control.

Brightness Adjusts the brightness of the converted colors. Range=0 to 200.
Default=50.
This parameter is animatable.
Contrast Adjusts the contrast of the converted colors. Range=0 to 100.
Default=50.
This parameter is animatable.
Exposure Value Adjusts the overall brightness of the rendering. Range= -5.0
to 5.0. Negative values make the image darker, and positive values make it
brighter. Default=0.0.
The exposure value can be thought of as an exposure compensation setting
in cameras with automatic exposure control.
This parameter is animatable.
