(19 x 24 cm) Finish Glossy Special Treatment None Exposures per Unit 15 exposures per box Reciprocity Performance The reciprocity characteristics of the film cause a color shift towards blue-cyan when the exposure time is increased and a color shift towards red-yellow when the exposure is decreased. The film is balanced for average daylight (5500°K) at 1/125 of a second (as well as for electronic flash units). Recommended filtration at other exposure times and with other illuminants is indicated on information packaged with the film. Development Time 60 seconds at 70°F 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. Limited Warranty See information on the film box.

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.

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.
