Film Data Sheet Technical Data T-579, T-679, & T-879 Instant Color Peel-Apart Films The information in this data sheet represents the typical performance of Polaroid's T-679, T-579 and T-879 color films. Specific film lots may vary. Characteristic H&D curves for normal development 3 H&D Curves @ 70oF/21oC Blue Green Recommended speed: ISO/DIN 100/21o 2 Sample Density Red Recommended processing time and temperature: 90 seconds at 70o -95o F (21o-35oC) Balance: Daylight and electronic flash (5500oK) Contrast: Medium 1 0 -3 -2 Relative Log Exposure -1 0 D-Max: The density value for the film's darkest black. 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. At 71o F/21o C: D-Max = 1. 8 D-Min = . 16 Slope = 1. 30 Characteristic H&D curves for cold development 3 H&D Curves @ 55oF/18oC Blue Green Red Sample Density 2 Sample Density 2 3 Characteristic H&D curves for hot development H&D Curves @ 95oF/35oC Blue Green Red 1 1 0 -3 -2 -1 Relative Log Exposure 0 0 -3 -2 -1 Relative Log Exposure 0 Film Data Sheet Technical Data T-579, T-679, & T-879 Instant Color Peel-Apart Films Spectral Sensitivity 40 Blue Green Reciprocity Law Failure Blue 2 Green Red 30 35 Relative Log Exposure Red Spectral Sensitivity 10 15 20 25 5 0 0 . 0001" 0. 4 0. 8 1. 2 1. 6 350 400 450 500 550 600 650 . 001" . 01" . 1" 1 10" 1 Wavelength (nm) Exposure Time (seconds) Action Sensitivity 1. 5 Blue Green Red Reciprocity: The ability of the film to respond in a constant manner to a constant exposure (light intensity x time ).
