EASTMAN Fine Grain Duplicating Panchromatic Negative
Film 5234/7234 and EASTMAN Fine Grain Duplicating
Panchromatic Negative Film 2234/3234, ESTAR Base, are
characterized by very high sharpness. They have
panchromatic sensitivity . These lo w-speed, black-and-white
films are designed for making duplicate negatives from
master positives, or internegatives from reversal originals.
When used with EASTMAN Fine Grain Duplicating
Positive Film 5366/7366, they produce negatives nearly
equal to the original negative in tone rendering and printing
detail.
BASE
5234/7234 Film has a gray acetate safety base. The back side
of the base contains an anti-static layer with a carnauba wax
lubricant.
2234/3234 Film has a gray ESTAR (polyester) base. The
backside of the base contains a process-surviving anti-static
layer.
DARKROOM RECOMMENDATIONS
Use a KODAK No. 3 Safelight Filter / dark green, with a
15-watt bulb, no closer to the film than 1.2 metres (4 feet).
STORAGE
Store unexposed film at 13°C (55°F) or lower. For extended
storage, store at -18°C (0°F) or lower. Process exposed fi lm
promptly. Store processed film according to the
recommendations in ANSI/PIMA IT9.11-1998: for
medium-term storage (minimum of ten years), store at 25°C
(77°F) or lower at a relative humidity of 20 to 50 percent; for
extended-term storage (for preservation of material having
permanent value), store at 21°C (70°F) or lower at a relative
humidity of 20 to 30 percent. For active use, store at 25°C
(77°F) or lower, at a relative humidity of 50 +/- 5 percent.
This relates to optimized film handling rather than
preservation; static, dust-attraction and curl-related
problems are generally minimized at the higher relative
humidity. After usage, the film should be returned to the
appropriate medium- or long-term storage conditions as
soon as possible.
For more information about medium- and long-term
storage, see ANSI/PIMA IT9.11-1998, SMPTE
RP131-1998, and KODAK Publications No. H-1, KODAK
Motion Picture Film, and No. H-23, The Book of Film Care.
PROCESSING
The following process recommendations should be used as
starting points for most conventional continuous-immersion
processors with solutions prepared according to the formulas
in KODAK Publication No.H-24.15, Manual for Pr ocessing
KODAK Motion Picture Films, Module 15. The processing
times may require modification for a particular machine.
Note: Observe precautionary information on product labels
and on the Material Safety Data Sheets.

In a conventional convection-type drying cabinet with air
at about 95°F (35°C) and 40 to 50 percent RH, drying will
take 15 to 20 minutes. With an impingement-type drying
cabinet, however, with a higher temperature and lower RH,
drying time is greatly reduced. With either type of dryer, the
film should be dry without tackiness 1/2 to 2/3 of the way
through. Upon cooling to room temperature after leaving the
dryer, the film should be in equilibrium with the room air at
approximately 50 percent RH.
IDENTIFICATION
After processing, the product code numbers 2234, 3234,
5234, or 7234; emulsion and roll identification; and
KEYKODE number (KD) are visible along the length of the
film.

IMAGE STRUCTURE
MTF
The modulation-transfer curves, the diffuse rms granularity ,
and the resolving-power data were generated from samples
of 5234 Film exposed with tungsten light and processed as
recommended in Process D-96 at 70°F (21°C) to the
recommended control gamma. For more information on
image-structure characteristics, see KODAK Publication
No. H-1, KODAK Motion Picture Film.

aperture.
The “perception” of the graininess of any film is highly
dependent on scene content, complexity, color, and density.
Other factors, such as film age, processing, exposure
conditions, and telecine transfer may also have significant
effects.
