RECIPROCITY
No filter corrections or exposure
adjustments for exposure times from
1/1000 of a second to 1/10 second. In the
1-second range, increase exposure 2/3
stop and use a KODAK Color
Compensating Filter CC 10R. In the 10-
second range, increase exposure 1 stop
and use a KODAK Color Compensating
Filter CC 10R.
IDENTIFICATION
After processing, the Kodak internal
product code symbol (EH), product code
numbers 5218 (35 mm) or 7218 (16 mm),
emulsion and roll number identification,
and EASTMAN KEYKODE Numbers are
visible along the length of the film.
GRAIN
The perception of graininess of any film
depends on scene content, complexity,
color, and density. In KODAK VISION2
500T Color Negative Film 5218 / 7218,
the measured granularity is
exceptionally low.
SHARPNESS
The perceived sharpness of any film
depends on various components of the
motion picture production system.
Camera and projector lenses, film print-
ers,and other factors play a role, but the
specific sharpness of a film can be
measured and charted in the Modulation
Transfer Curve.
COLOR BALANCE
This film is balanced for exposure with
tungsten illumination (3200 K). You can
also expose it with tungsten lamps that
have slightly higher or lower color
temperatures (± 150 K) without
correction filters, since final color
balancing can be done in printing. For
other light sources, use the correction
filters in the table below.
POST-PRODUCTION INFORMATION
When you transfer this film directly to
video, set up the telecine using negative
Telecine Analysis Film (TAF).
BASE
Acetate safety base with rem-jet
backing.
DARKROOM RECOMMENDATIONS
Do not use a safelight. Handle
unprocessed film in total darkness.
PROCESSING
ECN-2
STORAGE
Store unexposed film at 13°C (55°F) or
lower. For storage of unexposed film
longer than 6 months, store at –18°C
(0°F). Process film promptly.

SENSITOMETRIC CURVES ➤
"0" on the x-axis represents normal exposure
of an 18-percent gray card in the red, green, and
blue layers of this film. A white card is
2 1/3 stops higher than normal exposure,
and there are at least 2 1/2 stops above that
for capturing specular highlight detail.
A 3-percent black card is 2 2/3 stops below
normal exposure. There are at least 2 1/2
stops of latitude below that for capturing
shadow detail.
DIFFUSE RMS GRANULARITY CURVES ➤
To find the rms granularity value for a given
density, find the density on the left vertical scale
and follow horizontally to the sensitometric 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.
SPECTRAL-SENSITIVITY CURVES ➤
These curves depict the sensitivity of this film to
the spectrum of light. They are useful for
determining, modifying, and optimizing exposure
for blue- and green-screen
special-effects work.
SPECTRAL DYE-DENSITY CURVES ➤
These curves depict the spectral absorptions of
the dyes formed when the film is processed. They
are useful for adjusting or optimizing any device
that scans or prints the film.
NOTE: Cyan, Magenta, and Yellow Dye
Curves are peak-normalized.

MODULATION-TRANSFER CURVES➤
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 millimetre that can be resolved. The y-axis,
“Response,” corresponds to film sharpness. The
longer and flatter the line, the more sine waves
per millimetre that can be resolved with a high
degree of sharpness—and the sharper the film.
