DESCRIPTION
EASTMAN EKTACHROME Film 7239 (Daylight) is a
high-speed color reversal film intended for photography
under low-level daylight illumination. Among its many
applications are news photography, sporting events, and
high-speedphotography.Theprocessedoriginalcamerafilm
is ready for projection; because it is balanced for projection
at 5400 K, it is suitable for television broadcasting.
You can expose this film at effective film speeds ranging
from1⁄2 to 2 times the normal exposure indexes with little
loss in quality. For emergency situations when some loss in
quality is acceptable, increase the normal exposureindex by
the equivalent of 2 to 3 stops. When you expose the film at
other than the normal exposure index, tell the processing
laboratory so they can adjust the processing.
The processed camera original on EASTMAN
EKTACHROME Film (Daylight) is meant for direct
projection; however, you can make color duplicates on
EASTMAN EKTACHROME Print Film 7399.
BASE
This film has a clear acetate safety base.
DARKROOM RECOMMENDATIONS
Handle unprocessed film intotaldarkness until afterthestop
bath following first development. You can do the remaining
operations in anormally lighted room.Use a safelight with a
KODAK Safelight Filter No. 3 / dark green to illuminate
dials, meters, etc, duringfirst development; do not shine the
light directly on the film.
STORAGE
Store unexposed film at 13˚C (55˚F) or lower. Process
exposed film promptly. Store processed film at 21˚C (70˚F)
or lower ata relative humidity of40 to 50percent for normal
commercial storage. For more information on long-term
storage, see KODAK Publications No.H-1,KODAK Motion
Picture Film, and No. H-23, The Book of Film Care.

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.

subject includes only pastels, use at least1⁄2 stop less
exposure; dark colors require1⁄2 stop more exposure.

In the LADcontrol method,*the electronic coloranalyzer
used for color timing is set upwith the LAD Control Film to
produce a gray video display of the LAD patch,
corresponding to 1.0 neutral density (gray)on theprint. The
negative printing original is then scene-to-scene timed.
There are specific LAD values for each type of print or
duplicating film that the originalcan be printed on. Forprint
films, the LAD patchis printed to aneutral gray of 1.0visual
density. For duplicating films, the specified aims are at the
center of theusable straight-line portionof the sensitometric
curve of the film.
Lighting Contrast
The recommended ratio of key-light-plus-fill-light to fill
light is 2:1 or 3:1; you may use a 4:1 ratio if you want a
special look.
RECIPROCITY CHARACTERISTICS
You do not need any filter or exposure adjustments for
exposure times from 1 second to 1/10,000 second.
PROCESSING
This film may be processed in Process VNF-1, using either
ferricyanide or persulfate bleach, and in Process RVNP.
Force processing beyond 2 stops is not recommended.
EASTMAN EKTACHROME Film can be processed by
theindividual user, if desired. For information onprocedures
for machine processing the film, see KODAK Publication
No. H-24, Manual for Processing EASTMAN Motion
Picture Films.
IDENTIFICATION
The words “Eastman VND Safety Film” is latent-image
printed along the edge of the film.
FILM TO VIDEO TRANSFER
When you transfer the film directly to video, you can set up
the telecine with a negative Telecine Analysis Film (TAF)
supplied by Eastman Kodak Company. The TAFconsists of
aneutraldensity scale and an eight-bar color testpattern 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 TAFcolor bars provide the utilityof
electronic color bars, even though they do not precisely
matchtheelectronically generated color bars. Using the TAF
will help obtain optimum quality and consistency in the
film-to-video transfer.
For more information, see KODAK Publication
No. H-822, KODAK Telecine Analysis Film User’s Guide.
IMAGE STRUCTURE
The modulation-transfer curve, the diffuse rms granularity,
and the resolving-power data were generated from samples
of 7239 Film exposed to daylight and processed as
recommended in Process VNF-1. For more information on
image-structure characteristics, see KODAK Publication
No. H-1, KODAK Motion Picture Film.
LABORATORY AIM DENSITY (LAD) CONTROL METHOD
To maintain optimum quality and consistency in the final
prints, the laboratory mustcarefully controlthecolor timing,
printing, and duplicating procedures. To aid in color timing
and curve placement, negative originals should be timed
relative to the Laboratory Aim Density(LAD) ControlFilm

supplied by Eastman Kodak Company. The LAD Control
Film provides both objective sensitometric control and
subjective verification of theduplicating procedures usedby
the laboratory.
* The LAD control method is described in the paper “A Simplified
Motion-Picture Laboratory Control Method for Improved Color
Duplication,” by John P. Pytlak and Alfred W. Fleischer in the
October 1976 SMPTE Journal. Also refer to KODAK Publication

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 35 percent at the image plane, with
processing as indicated. In most cases, these 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.
Note: While the data presentedare typicalof productioncoatings, they
do not represent standards which must be met by Kodak. Varying
storage, exposure, and processing conditions will affect results. The
company reserves the right to change and improve product
characteristics at any time.
