2 KODAK VISION2 500T Color Negative Film 5218 / 7218 / SO-218 • H-1-5218t
EXPOSURE TABLE - TUNGSTEN LIGHT
At 24 frames per second (fps), 170-degree shutter opening:
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.
RECIPROCITY CHARACTERISTICS
You do not need to make any filter corrections or exposure
adjustments for exposure times from 1/1000 to 1/10 of a
second. If your exposure is in the 1 second range, it is
recommended that you increase your exposure by 2/3 stop
and use a KODAK Color Compensating Filter CC 10R. If
your exposure is in the 10-second range, it is recommended
that you increase your exposure by 1 stop and use a KODAK
Color Compensating Filter CC 10R.
PROCESSING
Process in Process ECN-2.
Most commercial motion-picture laboratories provide a
processing service for these films. See KODAK Publication
No. H-24.07, Processing KODAK Color Negative Motion
Picture Films, Module 7 available online at http://
www.kodak.com/US/en/motion/support/processing/
h24m7.shtml, for more information on the solution formulas
and the procedure for machine processing these films. There
are also pre-packaged kits available for preparing the
processing solutions. For more information on the
EASTMAN ECN-2 Kit Chemicals, check Kodak's Motion
Picture Films for Professional Use price catalog.

IDENTIFICATION
After processing, the product code numbers 5218 (35 mm),
7218 (16 mm), or SO-218 (16, 35, and 65 mm; edgeprint
shows 0218) emulsion, roll, and strip number identification,
KEYKODE Numbers, and manufacturer/film identification
code (EH) are visible along the length of the film.
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.

The LAD Control
Film provides both objective sensitometric control and
subjective verification of the duplicating procedures used by
the laboratory.
In the LAD Control Method,
3
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.
Due to normal variations in exposure and processing of
color negative films, particular scenes may not print exactly
at the same printer lights as the LAD Control Film. The LAD
Control Film is intended as a set-up tool for electronic color
analyzers and printers. It is NOT a reference that every scene
must match. Normal film-to-film and scene-to-scene
exposure variability is accommodated by the color timing
(grading) process, on an electronic color analyzer set up with
the LAD Control Film. Normally exposed and processed
color negatives will typically print well within the range of
an additive printer setup with the LAD Control Film,
although SIGNIFICANT or UNEXPECTED departures
from this center point balance may indicate an exposure/
filtration problem with the cinematography or with the
process control. Some specialized films and/or specialized
negative processing techniques (push-processing,
pull-processing, "skip-bleach" processing, etc.) may require
more extreme adjustment from the LAD printing condition
to attain desired results.
