             to lighten pixels that are already lighter than a certain threshold. Setting highlight to 100 specifies no change.
             Setting highlight to t specifies that a color channel value is increased if it is already greater than t percent
             of full intensity. For example, setting highlight to 90 specifies that all color channel values greater than 90
             percent of full intensity are increased.

             in the middle of the intensity range are altered more than color channel values near the minimum or maximum
             intensity. You can use this adjustment to lighten (or darken) an image without loosing the contrast between the
             darkest and lightest portions of the image. A value of 0 specifies no change. Positive values specify that the
             mid-tones are made lighter, and negative values specify that the mid-tones are made darker.
