2 KODAK DOUBLE-X AEROGRAPHIC Film 2405 • AS-75
IMAGE STRUCTURE
The following data are based on processing in KODAK
VERSAMAT Film Processors, Model 11, using KODAK
VERSAMAT Chemicals at the conditions noted.
*
Granularity values read at a net diffuse density of 1.0 with a
48-micrometre aperture.
Process conditions to achieve above values:
885 Chemicals:15 fpm, 85°F (29.5°C), process gamma 1.10
641 Chemicals: 5 fpm, 85°F (29.5°C), process gamma 1.30
Type A Chemicals: 10 fpm, 90°F (32°C), process gamma
1.65
STORAGE
For consistent results, all aerial films should be stored under
fairly constant conditions. Kodak aerial films are “usually”
packaged in equilibrium with 40 to 50 percent relative
humidity. High temperatures or high humidity may produce
undesirable changes in the film.
Unexposed Film
Store unexposed film in a refrigerator at 55°F (13°C) or
lower, or freezer at 0 to -10°F (-18 to -23°C), in the original
sealed container. If the film is stored in a refrigerator, remove
it about 2 hours before opening; if stored in a freezer, remove
it about 8 hours before opening. A sufficient warm-up time
is necessary to prevent moisture condensation on cold film --
otherwise, moisture spotting, ferrotyping, or sticking may
occur.
Exposed Film
Keep exposed film cool and dry. Process the film as soon as
possible after exposure to avoid undesirable changes in the
latent image. If it is necessary to hold exposed but
unprocessed film for several days (such as over a weekend),
it should be resealed and refrigerated at 40°F (4°C) or lower.
Before unsealing and processing exposed film that has been
held in cold storage, follow the warm-up procedures
described for unexposed film described above.

Processed Film
For best keeping, store processed film in a dark, dust-free
area at 50 to 70°F (10 to 21°C) and 30 to 50 percent relative
humidity. Preferably, store negatives on the spool or in
individual KODAK PROFESSIONAL Sleeves. High relative
humidity promotes the growth of mold and causes
ferrotyping. Very low relative humidity causes excessive curl
and brittleness. Avoid storage temperatures over 80°F
(27°C).
PROCESSING
KODAK DOUBLE-X AEROGRAPHIC Film 2305 can be
processed in KODAK VERSAMAT Film Processor, Models
11 and 1140, with KODAK VERSAMAT 885 Chemicals,
KODAK VERSAMAT 641 Chemicals, or KODAK
VERSAMAT Chemicals, Type A.
Mechanized processing in roller-transport processors
offers the advantages of uniform treatment of all portions of
the roll, freedom from banding, and absence of significant
density variations from ends of the roll to the center. Refer to
the operator’s manual for the processor set-up information,
but in all cases, the fixer replenisher should be introduced
into tank No. 5 of the processor with a countercurrent flow
to tank No. 3, where it overflows to a collection or recovery
system.
General instructions for setting the machine dryer
temperature are included in these pages. However, the
temperature of the dryer may require some further
adjustment, depending upon the ambient temperature
conditions in the processing area. Usually it is best to set the
temperature approximately 3°F (2°C) above that required to
dry unexposed, processed film.
