Abstract

The authors introduce a simple technique for lightening overexposed or overdeveloped dark radiographs. With the technique, an increase of exposure time in film duplicator allows production of duplicate radiographs with an appropriate tone. With this manipulation, image details are greatly improved, and the original radiograph is not damaged.
