Description
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 (strobe or short 
  exposures only)
• Final art
ILOP
• Test shots
• Large-format copystand photography
• Evidence documentation
• Photographic souvenirs
• Large-format photomicrography
• Materials and quality control documentation
• Special events photography

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.
Compatible Hardware
• MP-4+ Camera (w/ 8 x 10 head)
• 8 x 10 processor/ holder/ tray
• DayLab
Special Instructions
Force-drying prints:
Allow the print to air-dry for at least thirty (30) seconds before 
using a forced-hot-air dryer.
Viewing:
When evaluating the color balance of a print, use the same light 
source under which the print is to be viewed as a finished product.
Laminating prints:
This film is NOT recommended for use with laminates requiring a 
wet print to produce a photo-destruct bond.
Alternative Product
Use Polacolor 809 for emulsion lift

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.

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.
