SPATIAL FREQUENCY (cycles/mm)
Note: 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 60 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.
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.
