DARKROOM RECOMMENDATIONS
Handle unprocessed film in total darkness.
Using a safelight
will
affect your results. If absolutely
necessary, after development is half complete, you can use
a safelight equipped with a KODAK 3 Safelight Filter (dark
green) with a 15-watt bulb for a few seconds. Keep the
safelight at least 4 feet (1.2 metres) from the film. Run tests
to determine that safelight use gives acceptable results for
your application.
For information on safelight testing, see KODAK
