TOTAL FILM THICKNESS
The nominal total thickness (unprocessed) of each film is:
2403 Film: 4.55 mils (0.115 mm)
This includes emulsion—0.45 mils (0.010 mm), base—
3.9 mils (0.10 mm) and dyed-gel backing—0.20 mil
(0.005 mm).

Film 2403 can also be processed at normal temperatures in
conventional rewind equipment, such as the Gordon/Morse
M-10 Developing Outfit (Military Designator: B-5) using a
variety of Kodak black-and-white developers.
SO-050 Film: 3.15 mils (0.080 mm)
Caution: KODAK TRI-X AEROGRAPHIC and
AERECON Films are susceptible to static markings at low
relative humidities. These films are packaged at the optimum
relative humidity (45 to 50 percent) and are maintained at this
level by the sealed package. In conditions of low relative
humidity, these films should be loaded and used immediately
after the package is opened, before the film becomes too dry.
The camera should be checked to see that all its parts are
grounded adequately. Also, these films should be handled
carefully during all loading, unloading, and preprocessing
operations.
This includes emulsion—0.45 mils (0.011 mm), base—
2.5 mils (0.063 mm) and dyed-gel backing—0.20 mil
(0.005 mm).
WEIGHT
The weight of each film (unprocessed), conditioned in
equilibrium with 50 percent relative humidity, is:
2403 Film: 0.037 lbs⁄sq ft2 (0.0168 kg⁄ft2)
SO-050 Film: 0.021 lbs⁄sq ft2 (0.0095 kg⁄ft2)
SPECTRAL SENSITIVITY
Panchromatic, with extended red sensitivity.

Replenishment Rates
PROCESSING
Basic developer and fixer replenishment rates, in millilitres
per square inch of film processed, vary depending upon the
type of chemicals used. The following rates apply to
processing in the VERSAMAT Processor, Models 11 and
1140.
KODAK TRI-X AEROGRAPHIC and AERECON Films
can be processed in the KODAK VERSAMAT Film
Processor, Model 11 or 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.

REWIND OR SPIRAL REEL PROCESSING
DIMENSIONAL STABILITY
KODAK TRI-X AEROGRAPHIC Film 2403 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.
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.
KODAK TRI-X AERECON Film SO-050 is not
recommended for processing in conventional rewind
equipment due to the physical characteristics of its ESTAR
Thin Base.
