TECHNICAL DATA / COLOR NEGATIVE FILM
KODAK VISION2 250D Color
Negative Film 5205 / 7205
Give your story more detail—in any light.
STORAGE
KODAK VISION2 250D Color Negative Film 5205 / 7205
is an advanced, medium-speed film that delivers superior
imaging in natural daylight, artificial daylight, and a variety
of mixed lighting situations. Expect beautiful fleshtones,
accurate color reproduction, and-thanks to its wider
latitude-increased detail in shadow and highlight areas. Add
seamless intercutting with other KODAK VISION2 Films
and you have a versatile addition to your storytelling toolkit.
The VISION2 Film family is the first line of products
created specifically for both film and digital postproduction.
What's more, all VISION2 Films provide excellent tone
scale and flesh-to-neutral reproduction. With superior
shadow and highlight detail and very fine grain. VISION2
Films also maintain neutrality through the full range of
exposure. So you can convey exactly the look you intended
all the way from capture to post.
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://

BASE
KODAK VISION2 250D Film 5205 / 7205 has an acetate
safety base with rem-jet backing.
DARKROOM RECOMMENDATIONS
Do not use a safelight. Handle unprocessed film in total
darkness.
EXPOSURE INDEXES
Daylight (5500 K)—250 Tungsten (3200 K)—64 (with
KODAK WRATTEN Gelatin Filter No. 80A)
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
RECIPROCITY CHARACTERISTICS
These films are balanced for exposure with daylight
illumination (5500 K). For other light sources, use the
correction filters in the table below.
You do not need to make any filter corrections or exposure
adjustments for exposure times from 1/1000 to 1/10 second.
If your exposure is in the 1-second range, it is recommended
that you increase your exposure 2⁄3 stop and use a KODAK
Color Compensating Filter CC10R. If your exposure is in the
10 second range, it is recommended that you increase your
exposure by a stop and use a KODAK Color Compensating
Filter CC10R.

Use this table for average subjects that contain a
combination of light, medium, and dark colors. When a
subject includes only pastels, use at least 1/2 stop less
exposure; dark colors require 1/2 stop more exposure.
Lighting Contrast The recommended ratio of key-light-plus-fill-light to fill
light is 2:1 or 3:1. However, you may use 4:1 or greater
when a particular look is desired.
LABORATORY AIM DENSITIES (LAD)
To maintain optimum quality and consistency in the final
prints, the laboratory must carefully control the color timing,
printing, and duplicating procedures. To aid in color timing
and curve placement, negative originals should be timed
relative to Laboratory Aim Density (LAD) Control Film
supplied by Eastman Kodak Company.1 The LAD Control
Film provides both objective sensitometric control and
subjective verification of the duplicating procedures use by
the laboratory.
In the LAD Control Method,2 the electronic color analyzer
used for color timing is set-up with the LAD Control Film to
produce a gray video display of the LAD patch,
corresponding to 1.0 neutral density (gray) on the print. 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 original can be printed on. For print
films, the LAD patch is printed to a neutral gray of 1.0 visual
density. For duplicating films, the specified aims are at the
center of the usable straight-line portion of the sensitometric
curve of the film.
1.Direct any inquiries to one of the regional sales offices.
2.Use of 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.

FILM-TO-VIDEO TRANSFERS
CURVES
When you transfer the film directly to video, you can set up
the telecine using the negative Telecine Analysis Film (TAF)
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-9, TAF User's Guide.

IMAGE STRUCTURE
MTF:
Refer to curve.
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-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.

SPATIAL FREQUENCY (cycles/mm)
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.

To find the rms Granularity value for a given density, find
the density on the left vertical scale and follow horizontally
to the characteristic curve and then go vertically (up or
down) to the granularity curve. At that point, follow
horizontally to the Granularity Sigma D scale on the right.
Read the number and multiply by 1000 for the rms value.
