Special Treatment
Processing the film for longer than 3 minutes may affect
image contrast and density to some extent. For optimum
image stability at temperatures above 75°F (24°C), film should
not be processed for longer than one (1) minute. At colder
temperatures, process the film for a longer time as indicated
in the chart below. A picture processed for too short a time
will have dull grays, mottle and little contrast. However, if
more contrast is required, the processing time may be extended by 15 seconds (for example, process for 60 seconds
rather than 45 seconds). This may increase the contrast and
density, but may also result in some loss of gray.
Caution
This film uses a small amount of caustic paste. If any paste appears, avoid contact with skin, eyes and
mouth and keep away from children and animals. If you get some paste on your skin, wipe it off
immediately, then wash with water to avoid an alkali burn. If eye contact occurs, quickly wash the
area with plenty of water and see a doctor. Keep discarded materials away from children, animals, clothing
and furniture.

D-Max:
The density value for the film’s darkest black.
D-Min:
The lowest density value that a film exhibits. In
prints, the whiteness of the brightest highlight, relative
to the unprocessed print.
Slope:
The positive ratio of the log E increments of
the straight line region of the curve, as determined by
the 1/4-3/4 increment method. The slope of an H&D
curve indicates the overall contrast of a film: low
contrast slopes less than 1.10; medium contrast
slopes from 1.10 to 1.70; high contrast slopes greater
than 1.70.
