4 KODAK VISION2 500T Color Negative Film 5218 / 7218 / SO-218 • H-1-5218t
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 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.
Note: This curve represents granularity based on modified
measuring techniques.

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.
4.NOTE: Sensitometric and Diffuse RMS Granularity curves are
produced on different equipment. A slight variation in curve shape may
be noticed.

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.
NOTICE: The sensitometric curves and data in this
publication represent product tested under the conditions of
exposure and processing specified. They are representative
of production coatings, and therefore do not apply directly to
a particular box or roll of photographic material. They do not
represent standards or specifications that must be met by
Eastman Kodak Company. The company reserves the right
to change and improve product characteristics at any time.
