KODAK DOUBLE-X AEROGRAPHIC Film 2405
KODAK DOUBLE-X AEROGRAPHIC Film 2405 is a
panchromatic, negative aerial camera film with good contrast
for easier interpretation from negatives, high resolution, and
wide exposure latitude. Its extended red sensitivity permits

Aerial film speeds (ISO A or EAFS) should not be confused
with conventional film speeds which are designed for roll
and sheet films used in pictorial photography. The
The ESTAR Base provides flexibility, moisture
resistance, high tear resistance, and excellent dimensional
stability. This film has a thin, highly hardened, and
abrasion-resistant emulsion that permit high-temperature
rapid processing in modern continuous-processing
machines.
This film 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,

Film 2405 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
characteristics of aerial scenes differ markedly from those of
ordinary pictorial or ground scenes because of the smaller
range in subject luminances, atmospheric haze conditions,
and other factors. Therefore, different film-speed parameters
are used to relate aerial-scene characteristics to practical
exposure recommendations. The KODAK Aerial Exposure
Computer, KODAK Publication AS-10 has been published
based on the aerial film speed criterion.
Nominal speed, daylight (no filter): EAFS or ISO A 400
Other suggested aerial film speeds for processing this film
in the KODAK VERSAMAT Film Processor, Models 11 or
1140, using VERSAMAT 885 Chemicals, 641 Chemicals
and Type A Chemicals can be found in the sensitometric data
tables.
APPLICATIONS
KODAK DOUBLE-X AEROGRAPHIC Film 2405 is a
medium- to high-speed film for aerial mapping, charting, and
general aerial photography.
Note: The aerial film speeds given in this publication were
obtained by rounding the calculated values to the nearest
cube root of 2 step (equivalent to 1⁄3 stop).

The nominal total thickness (unprocessed) of this film is
4.50 mils (0.114 mm). This includes emulsion—0.40 mil
(0.010 mm), base—3.9 mils (0.10 mm), and backing—
0.20 mil (0.005 mm).
Typical Camera Exposure
A typical exposure for this film is approximately 1⁄750
second at f⁄8. This exposure is based on a solar altitude of 40
degrees, a clear day, an aircraft altitude of 5,000 feet, and a
speed of ISO A 400, using a 2X antivignetting filter.
WEIGHT
Reciprocity Characteristics
The weight of 2405 Film (unprocessed), conditioned in
equilibrium with 50 percent relative humidity, is 0.035 lbs⁄ft2
(0.0159 kg/ft2).
No exposure or development time adjustments are required
for exposure times from 1⁄1,000 second to 1⁄10 second; at
1⁄10,000 second, increase the development time by 10
percent.

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.

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.
