HDR Highlight Compression effect

The HDR Highlight Compression effect compresses the color values in a high -dynamic-range image so that they fall within the value range of a low-dynamic-range image.

Adjust the amount of compression by setting the Amount property for the effect. If the Amount value is set to 100%, color values are compressed so that no pixel has any channel value outside the low dynamic range of 0.0–1.0. At Amount settings less than 100%, the effect can still bring some detail into the visible range from highlight and shadow regions.
