Spectral-Sensitivity Curves
Modulation-Transfer Curve
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 35 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.
Note: 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
characteristics at any time.
