[. . . ] Film Data Sheet T-87 Black & White Pack Film Description 3URIHVVLRQDO % : 3DFN )LOP [ LQFK [ FP Medium-contrast, high-speed, general purpose black & white coaterless print film. ILOP 7\SH Key Applications · Document or passport photographs · Identification photographs Compatible Hardware · Miniportrait 485 or 485b · ProPack Camera 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. [. . . ] 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.

In prints, the whiteness of the brightest highlight, relative to the unprocessed print. [. . . ] 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. [. . . ]
