LUT_Emphasis

This control is applicable exclusively with the Emphasis parametric LUT definition method.

This control allows transforming an image using a power-law expression:

The g (gamma) exponent is mathematically linked to LUT_Emphasis by:

To achieve a required given g, the LUT_Emphasis control should be set to:

The default value of LUT_Emphasis is 0.
