RE-EXPOSURE<br />
Kodachrome FILMS are reversal, subtractive color materials. When properly exposed and processed, they yield<br />
direct positive color images.<br />
The figure above is a cross section (not to scale) of Kodachrome FILM that illustrates changes to the film during the<br />
process sequence. The transparent support (film base) has an antihalation backing layer called rem-jet. The rem-jet<br />
minimizes reflections of exposing light off the inner surface of the support, once it has passed through the film layers.<br />
These reflections cause "halo" images and loss of apparent sharpness in the processed films. The rem-jet backing is<br />
removed during the processing cycle.<br />
