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

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
Permanent Dimensional Changes
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
