Notice: While the data presented are typical of production
coatings, they do not represent standards which must be met
by Kodak. Varying storage, exposure, and processing
conditions will affect results. The company reserves the right
to change and improve product character- istics at any time.
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.
