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 designed for processing to a color negative only. Since this film does not have integral color masking, direct interpretation can be made from the negative. Objects are recorded in colors complementary to their natural colors.

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 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.

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.

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.

TOTAL FILM THICKNESS

The nominal total thickness (unprocessed) of this film is

5.2mils (0.132 mm). This includes emulsion—0.8 mil (0.020 mm), base—3.9 mils (0.10 mm), and backing—

0.5mil (0.013 mm).

WEIGHT

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).

SPECTRAL SENSITIVITY

This multilayer, color negative film is balanced for daylight exposure.

SAFELIGHT

Total darkness is required.

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.

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

3.9-mil(0.10 mm) ESTAR Base with a gel backing.

Filters

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.
