Parameters

shadows

An integer value which represents the amount of brightening that is applied to shadowed image area.

The range for this parameter is 0 - 100.

A value of 0 results in no brightening. Higher values indicate a greater increase of brightness to be applied to the highlighted image area.

highlights

An integer value which repesents the amount of brightness decreasing that is applied to the highlighted image areas.

The range for this parameter is 0 - 100

A value of 0 results in no decrease in brightness. Higher values indicate a greater decrease of brightness in shadowed image areas.

This method applies the same algorithm as the AutoLightness method to automatically balance color in the image, but enables the user to adjust the results of the algorithm by a specified amount.
