[. . . ] Film Data Sheet T-579 4 x 5 Pack Film Description 3URIHVVLRQDO &RORU 3DFN )LOP [ LQFK 10. 2 x 12. 7 cm 7\SH Film Speed ISO 100/DIN 21 ILOP Caution Medium-speed, medium-contrast, medium-grain, daylight and electronic flash balanced (5500°K) color print film. This film features accurate colors and bright whites; sharp, vibrant, saturated proofs and final art; lower contrast for greater detail when compared to Polaroid Pro 100 film; improved reciprocity characteristics, and fast clearing and drying. Key Applications · Professional photography (proofing and final art) · Passport/document photography · Scientific/industrial photography Compatible Hardware · Model 550 Film Holder Special Instructions Temperature affects the final image: Processing at temperatures above 95°F (35°C) or below 55°F (13°C) is NOT recommended. [. . . ] 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. Temperature °F °C 70-95 65-69 61-64 55-60 21-35 18-20 16-17 13-15 Proc.

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 ).
