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.

Reciprocity law failure
A wide range of shutter speeds can be used without loss of film speed.
For longer exposure times, some exposure compensation is suggested.

Reciprocity: The ability of the film to respond in a constant
manner to a constant exposure (light intensity x time).
Reciprocity failure occurs during very long or very short
exposures, requiring the photographer to increase exposure.
Spectral Sensitivity: Shows the equivalent energy needed
at each wavelength in order to activate the emulsion so that it
produces a neutral density of .75.
