Abstract
In a previous paper evidence was given that a step sector yields the same calibration curve for a photographic emulsion with either an intermittent light source or a continuous one, provided the emulsion has a negligible intermittency effect under the prevailing conditions. The data of that paper are now presented in a new way, based on that of the two-line method and the use of densities, transformed according to Seidel, which permits more definite conclusions. Evidence is given that the step sector yields the same calibration curve as the two-line method, in cases where it may be applied. The precision of both methods is compared; the step sector method proving to be less precise than the two-line method. Copyright © 1948 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
