title: Improved lighting techniques for reproducing radiographs on 35-mm rapid-process copy film.
abstract: A view box with blue fluorescent tubes was constructed to decrease exposure time when using 35-mm rapid-process copy film to photograph radiographs and other transparencies. The device reduced exposure time by 70%.
