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

illuminantto 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.
