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.

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 film instructions. 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 45 seconds rather than 30 seconds). This may
increase the contrast and density , but may also result in some loss
of gray .

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.
