Scene Exposure 2004-05-04 - By Jim Rothrock

Either:
1. Write an "exposure" output shader. Output shaders can read and write
the floating-point (before clipping and quantization) frame buffer color
values. The shader would have a single parameter of type "color," and would
multiply each frame buffer pixel by the shader parameter. This would work
like RenderMan's "Exposure" RIB command.
2. Save your rendered images in 32-bit floating-point TIFF format. You can
then vary the exposure after rendering by using a compositing program, such
as Shake, that can read floating-point TIFF files.
