Auto exposure can affect the lighting of the whole image.

Automatic Exposure Control samples the rendered image and builds a

histogram to give good color separation across the entire dynamic range of

the rendering. It can enhance some lighting effects that would otherwise be

too dim to see.

NOTE Automatic 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

Automatic exposure control.
