KODAK AEROCOLOR III Negative Film 2444
KODAK AEROCOLOR III Negative Film 2444 is a
medium-speed, very fine-grain color negative aerial film.
This film has a wide exposure latitude and is specifically
TOTAL FILM THICKNESS
The nominal total thickness (unprocessed) of this film is
5.2 mils (0.132 mm). This includes emulsion—0.8 mil
designed for processing to a color negative only. Since this
(0.020 mm), base—3.9 mils (0.10 mm), and backing—
film does not have integral color masking, direct
0.5 mil (0.013 mm).
interpretation can be made from the negative. Objects are
recorded in colors complementary to their natural colors.
WEIGHT
The ESTAR Base provides flexibility, moisture
resistance, high tear resistance, and excellent dimensional
stability. KODAK AEROCOLOR III Negative Film 2444
has an abrasion-resistant emulsion, an antihalation
undercoat, and a dyed-gel backing.
The weight of AEROCOLOR III Negative Film 2444
(unprocessed), conditioned in equilibrium with 50 percent
relative humidity, is 0.04 lbs⁄sq ft (0.018 kg⁄sq ft).
The hardened emulsion permits high-temperature, rapid
processing in roller-transport processors, such as the
KODAK Aerial Color Processor, Model 1611, and the
KODAK EKTACHROME RT Processor, Model 1811, with
Quick-Change, using Process AN-6. This process consists of
selected KODAK EA-5 Chemicals and AN-6 Chemicals.
Processing can be easily tailored to optimize contrast for
specific applications.
SPECTRAL SENSITIVITY
This multilayer, color negative film is balanced for daylight
exposure.
SAFELIGHT
Total darkness is required.
This film is also compatible with Process C-41. It can be
processed in existing C-41 processors using either KODAK
FLEXICOLOR Developer or KODAK Developer
Replenisher, Process AN-6.
This film can be processed in rewind processing
equipment, such as the Morse M-10 developing outfit
(Military Designator: B-5), although this is not a primary
processing recommendation.
EXPOSURE
Aerial Film Speeds (EAFS or ISO A equivalent) 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 luminance,
atmospheric haze conditions, and other factors. Therefore,
different film-speed parameters are used to relate
aerial-scene characteristics to practical exposure
recommendations.
APPLICATIONS
KODAK AEROCOLOR III Negative Film 2444 is for
general use in medium- to high-altitude aerial-mapping and
aerial-reconnaissance photography. It is suited for
geological, pollution, archeological, crop and forestry
studies; traffic control; city planning; railway, highway, and
hydraulic engineering; oceanography; and remote sensing, as
well as other areas where photogrammetry is used. It is also
well suited and recommended for use in digital film
recorders.
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 125
(based on development for maximum contrast)
Note: The Aerial Film Speed given in this publication is
rounded to the nearest cube root of 2 step (equivalent to 1⁄3
stop).
BASE
Filters
3.9-mil (0.10 mm) ESTAR Base with a gel backing.
This film incorporates an integral ultraviolet-absorbing filter,
so color correction filters are not normally used. If necessary,
additional color-balance adjustment in the blue region can be
achieved using KODAK Haze Cutting Filters HF-4 or HF-5.

C-41 Processing
This film may be processed in KODAK FLEXICOLOR
Chemicals for Process C-41. To achieve results like Process
AN-6, extend the development time to 5’15” at 100°F (38°C)
with a basic replenishment rate of 94 mL⁄ft2. Shorter
development times may be used to achieve lower contrast, if
desired. Substitute AN-6 Developer using a developer time
of 2’56” at 106°F (41°C) for increased productivity.

PROCESS CONTROL
KODAK Control Strips, Process AN-6, are available and are
recommended for monitoring the processing of
AEROCOLOR III Film in roller-transport processors. For
detailed information on process control and troubleshooting,
refer to KODAK Publication Z-200, Using Processes AR-5
and AN-5 for KODAK Color Aerial Films.

As needed
* If you increase the bleach and fixer times to 6:30 or longer, you can
extend the temperature range to 75 to 105°F (24 to 41°C).
† In some processors, a lower wash-water temperature may affect solution
temperatures in adjacent tanks. Longer warm-up times may be needed.
If it affects developer temperature during processing, you may need to
use a higher wash-water temperature.
‡ Rates are for first wash and a two-stage countercurrent final wash.
Double these rates for a single-stage final wash.
§ Use a two-stage (two-tank) countercurrent fixer, preferably with the
same time in each tank. Agitation and filtration in each tank are required.
If your processor has a single fixer tank, using in-line electrolytic
desilvering will decrease the safety factor for adequate fixing.
PRINTING NEGATIVES
You can reproduce images made on AEROCOLOR III
Negative Film by using a variety of Kodak materials.
¶
If your squeegees are efficient enough to maintain a low fixer carryover,
you can reduce the wash time to 2:10.
For additional information using Process C-41, see
KODAK Publication Z-131, Process C-41 using KODAK
FLEXICOLOR Chemicals.

DIMENSIONAL STABILITY
CURVES
The dimensional stability of aerial films is of particular
interest and importance in accurate mapping and in the
reproduction of maps.
Modulation Transfer Function
1000
100
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.
