Exposure Correction in Radiosity Pro

Exposure correction in Radiosity Pro is done in the Exposure Correction dialog, opened from the Exposure tab of the Radiosity Window.

When the Auto checkbox is selected, exposure is automatically adjusted. When it is unselected, the brightness can be adjusted using the slider in the Exposure Correction dialog.

To accurately see the effects different lighting settings have on a scene, deselect the Auto checkbox.
