Film Data Sheet Spectra Integral Color Print Film Description General-purpose, high-speed, medium-contrast, integral film for high definition instant color prints. It is balanced for daylight and electronic flash exposure. Compared to previous T-600 film chemistry, Spectra film has superior color performance, sharper images and better overall exposure performance. spectra film Key Applications (in Europe: Image Extreme) European Name Image Extreme Integral Color Print Film Film Speed ISO 640/DIN 29 · · · · · · · · · · · · · · · · · · · · Home or family photography Insurance photography Site & construction documentation Promotional photography Photographic souvenirs Healthcare documentation Law enforcement (domestic violence, child abuse, others) Jewelry documentation Medical imaging (clinical documentation) Manufacturing (ISO 9000 documentation) Compatible Hardware Format 4 x 41/8 in.

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. Do not cut or take apart pictures or battery. Do not burn battery or allow metal to touch terminals. Limited Warranty See information on the film box.

Film Data Sheet Technical Data Spectra Film Family The information in this data sheet represents the typical performance of Polaroid's Spectra film family. However, there may be some variation between film lots. Characteristic H&D curve for normal development 3 H&D Curves @ 70oF/21oC Blue Green Recommended speed: ISO/DIN 640/290 Recommended processing time and temperature: Approximately 3 minutes at 700F/210C Balance: Daylight and electronic flash (5500oK) Contrast: Medium Resolution (1000:1): 7-10 line pairs/mm 2 Red Sample Density 1 0 -3 -2 -1 0 Relative Log Exposure 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.

For longer exposure times, some exposure compensation and filtration is suggested. Reciprocity The ability of the film to respond in a constant manner to a constant exposure (light intensity x time). Reciprocity failure occurs during very long or very short exposures, requiring the photographer to increase exposure.
