When a sensor clips a colorful light source, the resulting diffusion in Scatter may end up appearing white because the chrominance of the pixels at the core of the source was not recorded.

The Highlight Color Recovery module attempts to rebuild color information in blown-out highlight regions by considering the hue of neighboring pixels so diffusion can be calculated more naturally.

Radius

The radius around the clipped pixels that are used to rebuild color. Larger clipped image regions may need larger radii.

Saturation

Boosts the saturation of the rebuilt color.

Cutoff

The luminance threshold above which a pixel is considered to be clipped and recovery is performed. Measured in number of stops above middle grey.
