4 KODAK DOUBLE-X AEROGRAPHIC Film 2405 • AS-75
Sensitometric Data
Model 1140 -- KODAK VERSAMAT Chemicals,
Type A
This is not a primary processing recommendation, although
satisfactory results can be obtained at processor speeds up to
10 feet per minute. Refer to the processing conditions and
sensitometric data for the KODAK VERSAMAT Processor,
Model 11, above.
REWIND OR SPIRAL REEL PROCESSING
KODAK DOUBLE-X AEROGRAPHIC Film 2405 yields
optimum results with modern, high-temperature,
continuous-processing machines. It can be processed in
rewind equipment or on spiral reels, although these methods
are not primary processing recommendations. Customers
wishing to use spiral reels or rewind equipment such as the
Gordon/Morse M-10 Developing Outfit (Military
Designator: B-5) may contact Aerial Systems for
information on exposure, processing chemicals, process
cycles, and general recommendations.

DIMENSIONAL STABILITY
The dimensional stability of aerial films is of particular
interest and importance in accurate mapping and in the
reproduction of maps.
Dimensional stability is an all-inclusive term. In
photography, it applies to size changes caused by changes in
humidity and in temperature, and by processing and aging.
The absence of solvent in ESTAR Base is one of the reasons
why ESTAR Base films show excellent dimensional
stability. The dimensional properties of ESTAR Base may
vary slightly in different directions within a sheet; the
differences that may exist, however, are not always between
the length and width directions.
Temporary Dimensional Changes
Permanent Dimensional Changes
Thermal Coefficient of Linear Expansion:
0.001% per degree F of change
0.0018% per degree C of change
Humidity Coefficient of Linear Expansion (Unprocessed):
0.002% per 1% change in relative humidity
Processing Dimensional Change:
-0.03% to +0.01% shrinkage to swell
Aging Shrinkage of Processed Film:
0.03% 1 week at 120°F (49°C), 20% RH
0.03% 1 year at 78°F (25.5°C), 60% RH
