Spectral-Sensitivity Curves
Modulation-Transfer Curves
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, the 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.
