LUT_Negative
This control is applicable with both the Response Control and the Emphasis parametric LUT definition methods. This control allows transforming an image into its negative counterpart, where black is substituted to white and conversely.
The following charts explain the negative effect for typical values of other controls. When the parameter Negative is set to TRUE, the transformation table is mirrored around a vertical axis in the graphs. This swaps the black and white values, and gives rise to a photographic negative effect. The default value is FALSE.
