Photographic Exposure Control rollout
The mr Photographic Exposure Control lets you modify rendered output with
camera-like controls: either a general exposure value or specific shutter speed,
aperture, and film speed settings. It also gives you image-control settings
including separate values for highlights, midtones, and shadows. It’s intended
for high-dynamic-range scenes rendered with the mental ray renderer on
page 6039 .
