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 
greater speed with the filters used for the reduction of 
atmospheric-haze effects.
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, 
Type A.  KODAK DOUBLE-X AEROGRAPHIC 
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
APPLICATIONS
KODAK DOUBLE-X AEROGRAPHIC Film 2405 is a 
medium- to high-speed film for aerial mapping, charting, and 
general aerial photography.
BASE
3.9-mil (0.10 mm) ESTAR Base with a dyed-gel backing
TOTAL FILM THICKNESS
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).
WEIGHT
The weight of 2405 Film (unprocessed), conditioned in 
equilibrium with 50 percent relative humidity, is 0.035 lbs

(0.0159 kg/ft

SPECTRAL SENSITIVITY
Panchromatic, with extended red sensitivity.
SAFELIGHT
Total darkness is required.
EXPOSURE
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 
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.
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.
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).
Filters
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.
Reciprocity Characteristics
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.
