It is ideal for pictorial photography and artistic photography. Its exposure latitude gives good results within an exposure range of EI 50/18 to EI 200/24. Enlargements of this film are particularly fine grain and extremely sharp.

|Storage and Handling
||Store unexposed film at 21°C (70°F) or lower in the original sealed package. For extended periods, store film at 13°C(55 °F) to preserve consistency. To avoid moisture condensation on film that has been refrigerated, allow the film to warm up to room temperature before opening the package
||Warm-Up Times (Hours) to Reach Room Temperature of 21°C (70°F) From a Storage Temperature of:
-18°C (0°F) -- 1,5 Hour
2°C (35°F) -- 1,25 Hour
13°C (55°F) -- 1 Hour
||Use the speed numbers in the tables below with cameras or meters marked for ISO, ASA, or DIN speeds or exposure indexes (EIs). Do not change the film-speed setting when metering through a filter. Metering through filters may affect light meter accuracy; see your meter or camera manual for specific information. For critical work, make a series of test exposures.
||Use the exposures in the table below for average frontlit subjects from 2 hours after sunrise to 2 hours before sunset.

Adjustments for Long and Short Exposures
No filter correction or exposure compensation is required for PORTRA 160 Film for exposures from 1/10,000 second to i second. For critical applications with longer exposure times, make tests under your conditions.
||Use the appropriate guide number in the table below as starting-point recommendations for your equipment. Select the unit output closest to the number given by your flash manufacturer. Then find the guide number for feet or metres. To determine the lens opening, divide the guide number by the flash-to-subject distance. If negatives are consistently too dense (overexposed), use a higher guide number; if they are too thin (underexposed), use a lower number.
||Process PORTRA 160 Film in KODAK FLEXICOLOR Chemicals for Process C-41 using the replenishment and wash rates in the tables below. Note that the developer replenishment rates are starting-point recommendations only and may vary due to the amount of exposure to the film, scene content, and the presence/absence of sprocket holes.
