This page provides information about the Unclamped Color render channel in V-Ray for Blender.
Overview
The Unclamped Color Render Channel is a color image that shows the original colors that were clamped or adjusted with Color Mapping. This render element is useful in the compositing process for enhancing extreme colors (very bright or very dark) or for shading the final image with the unclamped colors.
When Color Mapping is used, the values that are clamped depend on whether the Clamp Output option has been enabled, as well as the rest of the Color Mapping parameters.
