Load and unload roll-film cameras in subdued light. Total darkness is required when you load and unload sheet film
Process film as soon as possible after exposure. Protect negatives from strong light, and store them in a cool, dry place. For long-term storage, keep negatives at a temperature between 2C (35F) and 13C (55F) and at a relative humidity between 30 and 35 percent.
Note: High speed films, such as PORTRA 800 Film, are sensitive to environmental radiation. Expose and process this film promptly. As exposure to radiation is cumulative, you may want to request visual inspection of PORTRA 800 film at airport and other security x-ray inspection stations.
DARKROOM RECOMMENDATIONS
Do not use a safelight. Handle unprocessed film in total

Film Speed
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.
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.

Fluorescent and High-Intensity Discharge
Use the color-compensating filters and exposure adjustments in the tables below as starting points to expose
PORTRA Films under fluorescent or high-intensity discharge lamps. For critical applications, make a series of test exposures under your actual conditions.
To avoid the brightness and color variations that occur during a single alternating-current cycle, use exposure times of 1?60 second or longer with fluorescent lamps; with high-intensity discharge lamps, use exposure times of
1?125 second or longer.
