Enhancements are applied to values within the bounds defined by the x-axis and y-axis markers.
The vertical markers set the minimum and maximum output grayscale values. The horizontal markers set the range of input grayscale values for an enhancement.
To allow tail trimming, enable the Tail Trim check box. In the Tail Trimming list box, select the tail trim percent from 1 to 5. You can also enable the Exclude Min./Max check box and enter values in the appropriate boxes. Once you apply an enhancement, you can customize it.
The view with the changes in the histogram window is automatically updated.
