COLOR REVERSAL FILM

K OD AK EKTA CHR OME 64T Color
Rever sal Film 7280

May 2005 • H-1-7280t

KOD AK EKTACHR OME 64T Color Reversal Film 7280 is
a 64-speed color reversal motion picture camera film
designed for exposure with tungsten illumination (3200 K).
This film offers excellent color reproduction, f ine grain, and
high sharpness. 7280 has outstanding reciprocity
characteristics, which give consistent color balance and
speed over a wide range of exposures. EKTACHR OME 64T
Film should be processed in an E-6 Process.

Manufacturing Code Size

7280 Super 8 Silent x 50 ft

BASE

KODAK EKTACHROME 64T Color Reversal Film 7280 has an acetate safety base.

DARKROOM RECOMMENDATIONS

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

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 10°C
(50°F) or lower at a relative humidity of 20 to 30 percent; for
extended-term storage (for preservation of material having
permanent value), store at 2°C (35°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 RP131-2002, and KODAK Publications No. H-1, KODAK Motion Picture Film available online at http:// www.kodak.com/US/en/motion/support/h1, and No. H-23, The Book of Film Care.

EXPOSURE INDEXES

Tungsten (3200 K) - 64 / Daylight (5500 K) - 401

Use these indexes with incident- or reflected-light
exposure meters and cameras marked for ISO or ASA speeds
or exposure indexes. These indexes apply for meter readings
of average subjects made from the camera position or for
readings made from a gray card of 18-percent reflectance
held close to and in front of the subject. For unusually light­or dark-colored subjects, decrease or increase the exposure
indicated by the meter accordingly.

COLOR BALANCE

These films are balanced for exposure with tungsten illumination (3200 K). For other light sources, use the correction filters in the table below.

FILM-TO-VIDEO TRANSFERS

When you transfer the film directly to video, you can set up
the telecine using the KODAK EKTACHROME Telecine
Analysis Film (T AF) supplied by Eastman Kodak Company .
The TAF consists of a neutral density scale and an eight-bar
color test pattern with a LAD gray surround.

The TAF gray scale provides the telecine operator
(colorist) with an effective way to adjust subcarrier balance
and to center the telecine controls before timing and
transferring a film. The TAF color bars provide the utility of
electronic color bars, even though they do not precisely
match the electronically generated color bars. Using the
TAF will help obtain optimum quality and consistency in the
film-to-video transfer. For more information regarding
TAF, see KODAK Publication No. H-822, KODAK Telecine
Analysis Film User's Guide.

IMAGE STRUCTURE

The modulation-transfer curves, and the diffuse rms granularity data were generated from samples of 7280 Film exposed with tungsten light filtered to 3200 K and processed as recommended in Process E-6 chemicals.

MTF:

The "perceived" sharpness of any film depends on various
components of the motion picture production system. The
camera and projector lenses and film printers, among other
factors, all play a role. But the specific sharpness of a film
can be measured and charted in the Modulation Transfer
Curve.

rms Granularity:

Refer to curve. Read with a microdensitometer, (red, green, blue) using a 48-micrometre 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

This graph shows a measure of the visual sharpness of this
film. The x-axis, "Spatial Frequency," refers to the number
of sine waves per millimeter that can be resolved. The y-axis,
"Response," corresponds to film sharpness. The longer and
flatter the line, the more sine waves per millimeter that can
be resolved with a high degree of sharpness—and, the
sharper the film.
