degrees Celsius (C)) or lower. If this is not possible, then protect film
from direct sunlight, heat, radiators, etc.
Nonprofessional films can be
stored at room temperature.
Professional films must be kept under
refrigeration.
c. Humidity. High relative humidity will harm color film more quickly
than high temperatures. Relative humidity of film should be maintained at
40 percent where possible. Keep film in its original container until ready
to use.
d. Atmospheric Elements.
Harmful gases, such as gasoline vapors, can
attack film emulsions.
Always keep film in its original container before
shooting.
When film has been exposed, replace as much of the original
wrapping as possible. Additional protection may be necessary depending on
your location and climate.
e. Opening Precautions.
Films stored under refrigeration must not be
opened immediately upon removal from storage. They must be allowed to warm
up gradually. If not, moisture will condense on the film emulsion. Always
allow film to warm up slowly.
Usually, one hour is sufficient before
opening the package.
Always refer to the manufacturer's instructions for
proper time.
