DESCRIPTION

EASTMAN Color Internegative II Film 5272 (35 mm) 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 suitable filters in the light path. The internegatives can then be printed onto KODAK Color Print Film and EASTMAN

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.

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.

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 by 1

⁄

stop and use a KODAK Color

Compensating Filter 10Y.

PROCESSING

Most commercial motion-picture laboratories provide a processing service for this film. Pre-packaged kits are also available for 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

Processing KODAK Motion Picture Films, Process ECN-2

Specifications, Module 7, for more information on the solution formulas and the procedures for continuous machine processing this film.

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 by Eastman 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, chosen to be at the center of the usable straight-line portion of the duplicating film’s characteristic curves. The Status

M Laboratory Aim Density values for EASTMAN Color

Internegative II Film are as follows:

Red

0.90

Green

1.30

Blue

1.70

Tolerance

±

0.12 density

For making prints, the processed internegative may then 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

Internegative II Film 5272 / 7272, include a 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

Modification Filters in subtractive printers to more closely balance the spectral characteristics of subtractive lamphouses with additive lamphouses so that prints made on a subtractive printer more closely match those made 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

EASTMAN Color Negative II Film exposed with tungsten light and processed as recommended in Process ECN-2 chemicals. For more information on image-structure characteristics, see KODAK Publication No. H-1, KODAK

Professional Motion Picture Films.

These photographic modulation-transfer values were determined by using a method similar to the one described in

ANSI Standard PH2.39-1977(R1990). The film was exposed with the specified illuminant to spatially varying sinusoidal test patterns having an aerial image modulation of a nominal

60 percent at the image plane, with processing as indicated.

In most cases, the photographic modulation-transfer values are influenced by development-adjacency effects and are not equivalent to the true optical modulation-transfer curve of the emulsion layer in the particular photographic product.
