Kodak EL Camera Film
Technical Information Instruction Sheet – TI2104
August 2006
Features / Customer Product Specifications
• A high-contrast, stabilized gelatin, orthochromatic film for making camera-line or copy-dot negatives
or positives.
• High maximum density.
• Can also be used for making contact negatives and positives.
• Matte level sufficient to permit quick and uniform vacuum drawdown.
• Good reciprocity and latent image keeping characteristics.
• Product can be used in most conventional rapid-access developers such as Kodak RA 2000 developer
and replenisher.
• Dimensionally stable Estar base.
Safelight Recommendations
Use a Kodak 1A safelight filter / light red in a suitable safelight lamp equipped with a 15-watt bulb. Keep
the film at least 4 feet (1.2 metres) from the safelight.
Storage
Keep unexposed film and processed film in a cool, dry place. Process film as soon as possible after
exposure.
Exposure
Relative Exposure Index
Orientation System Pulsed-Xenon Tungsten or Quartz-Halogen
Emulsion exposure ISO/ASA System 5 4
ISO/DIN System 8 7
Exposed through base ISO/ASA System 2 2
ISO/DIN System 5 3
These indexes are provided primarily as indicators of the relative speed of this film when compared with
other Kodak graphic arts materials when processed in lith developers.
The pulsed-xenon value indicates the film's relative speed to pulsed-xenon illumination as measured by a
light integrator. Index numbers for the other light sources can be used with photoelectric exposure
meters to help establish trial exposures.
One camera stop increase is indicated in the ASA System by doubling the index number and in the DIN
System by increasing the number by three.
Examples of Camera Exposures
Camera-Line- For lith developers
For a same-size (1:1) line reproduction with two 1500-watt pulsed-xenon lamps in reflectors about 3 feet
(0.9 metre) from the center of the copyboard, expose for about:
15 seconds at f/22 (exposure to the emulsion)
30 seconds at f/22 (exposure to the base)
Contact- Processable in lith developers
Starting-point examples of exposure are given below when using a modified Kodak adjustable safelight
lamp, or equivalent. Set the lamp at 16 volts at a distance of 5 feet (1.5 metres) from the exposure
plane—approximately 4 footcandles (43 lumens per square metre).
To emulsion 5 to 15 seconds1
Through base 10 to 30 seconds1
1 With a Kodak Wratten gelatin filter / neutral density filter No. 96 (0.9)
Filter Factors
When a filter is used, multiply the unfiltered exposure by the filter factor for the particular filter shown
below. Since lighting conditions vary, these factors are only approximate:
Orientation Light Source Kodak Wratten Gelatin Filter
No. 8 No. 15 No. 47B No. 58
To the emulsion Pulsed-Xenon 2.0 3.5 12.0 4.0
Quartz-Halogen 1.5 2.5 40.0 3.5
NOTE: It is recommended that the manufacturer of the pulsed-xenon or quartz-halogen lamps be
consulted for safety information pertaining to ultraviolet radiation and ventilation requirements due to
ozone generation.
Processing
Notice: Observe precautionary information on products labels and on the Material Safety Data Sheets.
Tray Processing
1. DEVELOP with continuous agitation at 68° F (20° C).
Developer Recommended Time (Minutes) Useful Range1(Minutes)
Rapid Access:
Kodak Professional D-11 developer 1 ½ 1 to 4
Kodak RA 2000 developer and replenisher (1:4) 1 ½ 1 to 4 ½
Kodak RA 2001 1 ½ 1 to 3
Lith:
Kodalith Super RT developer 2 ½ 1 ¾ to 2 ¾
Kodalith Liquid (1:3) 2 1 ½ to 2 ½
1 With this range of development times, satisfactory results can usually be obtained.
2. RINSE at 65° to 80° F (18° to 27° C) with agitation.
Kodak indicator stop bath 10 seconds
or diliuted 4% acetic acid solutions 10 seconds
3. FIX at 65° to 80° F (18° to 27° C) with frequent agitation.
Kodak RA 3000 fixer and replenisher 1 to 2 minutes
Kodak rapid fixer 1 to 2 minutes
Kodak fixer 2 to 4 minutes
4. WASH at 65° to 80° F (18° to 27° C) in running water for about 10 minutes.
5. DRY in a dust-free place.
Mechanized Processing
The recommended starting point for optimum results using Kodalith blender concentrates is:
Deep-Tank Processors 1 min 15 sec at 80° F (26.5°C)
The recommended starting point for optimum results using Kodak RA 2000 developer and replenisher
(1:4) is:
Rapid Access Processors 30 seconds at 95°F (35°C)

Technical Information Data Sheet – TI2104

1. Support
Dimensionally Stable Support
EL Camera film 4 mil (0.004 in., 0.10 mm) Estar base
2. Dimensional Stability
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 the Estar
base is one of the reasons that Estar base films show excellent dimensional stability. The dimensional
properties of the Estar base may vary slightly in different directions within a sheet; the differences that
may exist, however, are not always equal in both the length and width directions.
Differences in size change between length and width should be within 10 percent of each other.
Determined in accordance with ISO Standard.
Thermal Coefficient of Linear Expansion
Unprocessed or Processed 0.001% per °F (0.0018% per °C)
Humidity Coefficient of Linear Expansion
Unprocessed 0.0016% per % RH
Processed 0.0014% per % RH
Processing Dimensional Change
Dependent on drying conditions
3. Reciprocity
With recommended processing, the reciprocity speed change is negligible (1/3-photographic stop or
less) within exposure range of 1/1000 second to 100 seconds; there is no change in contrast.
