ILOP 7\SH 84 Key Applications · Professional photography proofing · Test shots less than 1/10 second or with strobe · Scientific imaging (strobe or shorter exposures only) Compatible Hardware Film Speed ISO 100/DIN 21 · Cameras or instruments with CB-1034 or CB-80 camera backs · MiniPortrait Camera models M484, M485b, M486V, and M488V · ProPack Camera Special Treatment Processing the film for longer than 3 minutes may affect image contrast and density to some extent. [. . . ] (6. 9 x 7. 2 cm) Finish Glossy Exposures per Unit 10 exposures per pack Development Time 30 seconds at 70°F (21°C) 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.

Sample Density 2 D-Max: The density value for the film's darkest black. In prints, the whiteness of the brightest highlight, relative to the unprocessed print. 1 0 -3 -2 -1 Relative Log Exposure 0 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. [. . . ] 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. [. . . ]
