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. Do not cut or take apart pictures or battery. Do not burn battery or allow metal to touch terminals.

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.
