Enhancing images

Images can be processed at several levels, from standard enhancements that filter images to fully customized enhancements using lookup tables and histograms. Unenhanced image files are often difficult to interpret visually when they are opened in an image viewer. Enhancements make imagery clearer and easier to interpret. When you open an image file, it is enhanced automatically in the view pane based on the default enhancement. You can change the default, if necessary.
