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.
