An investigation is developed for determining whether certain factors, which are characteristics of a photographic edge, are of significance in the derivation of the modulation transfer function of a system from the edge. Factors investigated were edge spread, density range (contrast), and background density. The experiment was limited as to levels used but it was determined that the edge spread significant and a minimum allowable edge spread was calculated.
