Negative Film 5234, 7234

TECHNICAL DATA

EASTMAN Fine Grain Duplicating Panchromatic Negative
Film 5234/7234 is a panchromatic film characterized by
very high sharpness. This low-speed, black-and-white film
is designed for making duplicate negatives from master
positives, or internegatives from reversal originals. When
used with EASTMAN Fine Grain Duplicating Positive Film
5366/7366, it produces 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.

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 film
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 Processing 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.

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.

rms Granularity

Refer to curve.

Read with a microdensitometer using a 48-micrometer

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.
