The Law Library Digitization Project of the Rutgers University School of Law in Camden, New Jersey, developed a Perl script to use the open-source module PerlMagick to automatically adjust the brightness levels of digitized images from scanned microfiche. This script can be adapted by novice Perl programmers to manipulate large numbers of text and image files using commands available in PerlMagick and ImageMagick.
