STORAGE AND HANDLING

Load and unload your camera in subdued light. High temperatures or high humidity may produce

unwanted quality changes. Store unexposed film at 24° C (75° F) or lower in the original sealed package. Always store film (exposed or unexposed) in a cool, dry place. For best results, process film as soon as possible after exposure.

Protect processed film from strong light, and store it in a cool dry place. For more information, see KODAK Publication No. E-30, Storage and Care of KODAK Films and Papers—Before and After Processing.

It may be difficult to use the table to estimate the adjusted times for calculated exposure times between 1 and

100 seconds. The graph that follows will help you find the adjusted times for calculated exposure times between those given in the table.
