Film: BRF-100 Fine Grain Panchromatic Black and White
Film
BRF-100 is a panchromatic black and white,
very fine grain film for general outdoor and studio photography.
Outdoor daylight exposure
Automatic cameras and electric exposure meters should
be set for a speed value according to the film used (100 ASA).
Without exposure meter, it is recommended to used an exposure time of
1/250 sec with different lens openings.
Indoor exposure
BRF-100 films are particularly sensitized
for indoor exposures, giving excellent results by artificial light.
Processing
The films BRF 100 should be handled in total darkness.
After development is half completed, you can use a Kodak # 3 safelight
filter (dark green) with a 15 watt bulb for a few second. Keep safelight
at least 3 feets from the film.
The recommended developers and developing conditions are included in the
chart enclosed.
Continuous agitation of the tank is recommended in the first minute of
development, then provide agitation of 5 sec. every 30 seconds for remaining
development time.
Due to inherent variations in individual agitation methods and equipment,
these recommendations should be used only as a starting point.
Storage and Handling
Store unexposed film in a cool dry place, in the original
sealed package. Process film promptly after exposure.
