Clip Low Values
The Clip Low Values command removes extreme pixel values by clipping them below a specified value. Any pixel having a value less than the target value is replaced with a new value. Unlike the Cosmic Ray Filter, no statistical test is made to detect extreme values. The Clip High Values command does the opposite of this command by clipping values above a threshold.
The Clip Low Values command opens from
the Image Window > Process >
Filters menu and 
button
on the Main Toolbar. The "immediate"
form, shown first, opens when an image or image set is displayed in
the top-most window. The general form can be used to select source
images from folders, windows, or by matching templates.
