Film Data Sheet Technical Data T-779 and T-339 (AutoFilm) Integral Color Print Film The information in this data sheet represents the typical performance of Polaroid's Type 779 and 339 color films. Specific film lots may vary. Characteristic H&D curve for normal development 3 H&D Curves @ 70 oF/21oC Blue Green Red Recommended speed (ISO) Recommended processing time and temperature Resolution (1000:1) Contrast 640 / 29 o Self-timing 2 7 - 10 line pairs/mm Medium Sample Density 1 0 -3 -2 Relative Log Exposure -1 0 Processing time and temperature For best results process at temperatures above 60oF(16oC). o F o C Time in seconds 2 min. Image Emergence 70 21 D-Max: The density value for the film's darkest black. In prints, the whiteness of the brightest highlight, relative to the unprocessed print. Sample Density Characteristic H&D curve for cold development 3 3 Characteristic H&D curve for hot development H&D Curves @ 95 oF/35 oC Sample Density 2 Blue Green Red H&D Curves @ 55 oF/18 oC 2 Blue Green Red 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. 1 1 0 -3 -2 -1 0 0 -3 -2 -1 0 Relative Log Exposure Relative Log Exposure Film Data Sheet Technical Data T-779 and T-339 (AutoFilm) Integral Color Print Film Reciprocity law failure A wide range of shutter speeds can be used without loss of film speed or requirements for color filtration. For longer exposure times, some exposure compensation and filtration is suggested. [. . . ] Reciprocity failure occurs during very long or very short exposures, requiring the photographer to increase exposure. [. . . ]
