Visibility Parameter

The Visibility parameter exclusively applies to the Response Control lookup table definition method.

The operation of Contrast and Brightness parameters occasionally removes some part of the input dynamics. Very dark regions of the image can be transformed into full black, and become invisible. This holds true for very bright regions, clipping to full white.

The Visibility parameter has been created to smoothly reveal these hidden parts in the image.

Visibility Gain Note
0.00 0.01

Minimum and default Visibility value.

This generates the piecewise linear transformation curves. Choosing values closer to +1 generates smoother curves.
1.00 100 Max. Visibility value.

The following charts explain the Visibility effect for typical values of Contrast and Brightness parameters assuming that Negative = FALSE.
