Light Return

In the Diamond Cut Study the light return was measured under different lighting conditions. However, this takes a lot of time. In this Gem Adviser demo the light return is computed for single lighting.

To learn how the specific of the human perception is considered in Light Return estimation please read this article:
Taking into account the features of human perception
