DESCRIPTION

EASTMANColorInternegativeIIFilm5272(35mm)and
7272 (16 mm) is a medium-speed film with excellent
image-structure characteristics and color-correction
masking. It is intended for making 35 mm or 16 mm
internegatives from reversal color originals on
EASTMAN EKTACHROME Film 7240™. This film is
balanced for printing with tungsten illumination with
suitablefiltersinthelightpath.Theinternegativescanthen
beprinted onto KODAKColorPrintFilmandEASTMAN
EXR Color Print Film.

BASE

This film has a clear acetate safety base with rem-jet
backing.

DARKROOM RECOMMENDATIONS

Do not use a safelight. Handle unprocessed film in total
darkness.

RECIPROCITY CHARACTERISTICS

You do not need to make any exposure or filter
adjustments for exposure times from 1/1000 to 1/10
second. For exposure time of either 1 or 5 seconds,
increase exposure by1⁄2 stop and use a KODAK Color
Compensating Filter 10Y.

PROCESSING

Most commercial motion-picture laboratories provide a
processing service for thisfilm. Pre-packaged kits arealso
availablefor preparing the processing solutions. For more
information on the EASTMAN ECN-2 Kit Chemicals,
check Kodak’s Professional Motion Imaging Price
Catalog or see a Kodak sales representative in your
country. See KODAK Publication No. H-24, Manual for

ProcessingKODAK Motion PictureFilms,Process ECN-2
Specifications, Module 7, for more information on the

solution formulas and the procedures for continuous
machine processing this film.

STORAGE

Store unexposed film at 13˚C (55˚F) or below. Process
exposed film promptly. Store processed film at 21˚C

(70˚F) or lower at a relative humidity of 40 to 50 percent
for short-term commercial storage; for long-term storage,
store it at 2 to 10˚C (35 to 50˚F) at 15- to 30-percent
humidity.For more information on long-term storage, see
KODAK Publication H-23, The Book of Film Care.

IDENTIFICATION

After processing, the product code numbers 5272 and
7272; emulsion and roll number identification;
EASTMAN KEYKODE Numbers; and a film
identification code (S) are visible along the length of the
film.

LABORATORY AIM DENSITY (LAD) CONTROL METHOD

To maintain optimum quality and consistency in the final
prints, the laboratory must carefully control the color
timing, printing, and duplicating procedures. Laboratory
Aim Density (LAD) Control Film provides a simple,
effective, and easily implemented control method for the
production of master positives and duplicate negatives
from negative originals.

All film in the printing original should be color timed
relative to LAD Control Film supplied byEastman Kodak
Company. The reversal LAD control film specified may
be made on EASTMAN EKTACHROME Film 7240
flashed and processed to Status M densities of Red 1.10,
Green 1.10, and Blue 1.10. The LAD Control Film is
printed at the center of the printer range, usually
TAPE 25-25-25. Printer setup (speed, bulb voltage,
TRIM, filtration, etc.) is determined by printing the large
gray patch in the LAD Control Film to the specified
Laboratory Aim Density values on the duplicating film,

of the duplicating film’s characteristic curves. The Status
M Laboratory Aim Density values for EASTMAN Color
Internegative II Film are as follows:

Red Green Blue Tolerance

0.90 1.30 1.70 ± 0.12 density

Formakingprints,theprocessedinternegativemaythen
be timed relative to a negative LAD Control Film using
densitometry or an electronic color analyzer. On-aim
internegatives and duplicate negatives will normally time
near TAPE 29-29-29 compared to the negative LAD
Control Film printed at TAPE 25-25-25. The LAD on the
print film is a neutral gray of 1.0 visual density. The LAD
Control Method* assumes that the film and process
sensitometry are within specification.

PRINTING CONDITIONS

In all printer setups for printing EASTMAN Color
InternegativeIIFilm5272/7272,includea heat absorbing
(infrared) filter such as a KODAK Heat Absorbing Glass,
No. 2043, and a KODAK WRATTEN Gelatin Filter No.
2B to absorb ultraviolet (UV) light. For high light output
with very long bulb life, operate the printer bulb at
approximately 80 percent of rated voltage. Use a
well-regulated constant-current dc power supply.

Print the LAD Control Film at the center of the printer
balance range, usually TAPE 25-25-25 on an additive
printer. Print other scenes in the original as determined by
color timing relative to the reversal LAD Control Film.
Choose the printer speed and filtration to normalize the
additive TRIM settings near the center of their range to
allow for slight variations in film and printer.

On subtractive printers, choose the filter pack and light
control for both the removal and addition of filters for
color correction. You can use EASTMAN Lamphouse
ModificationFilters in subtractive printers to more closely
balance the spectral characteristics of subtractive
lamphouses with additive lamphouses so that prints made
on a subtractive printermore closely match thosemade on
additive printers. On optical printers, set the lens aperture
considering sharpness, depth of focus, and light
transmittance characteristics. Use ground glass or other
diffusers to improve uniformity of illumination. Clean and
align optics for optimum light output and uniformity.

IMAGE STRUCTURE

The modulation-transfer curve, rms granularity, and
resolving-power data were generated from samples of

light and processed as recommended in Process ECN-2
chemicals. For more information on image-structure
characteristics,seeKODAKPublicationNo.H-1,KODAK
