Abstract
Predictions of the nucleation-and-growth model of latent-image formation are discussed with regard to the fraction of latenl-subimage grains expected under various experimental situations. Detecting these subimage grains under practical conditions with low-intensity post-exposure light latensification usually involves correcting for fog induced by the post exposure. Two procedures for correcting this fog (one due to Farnell, Jenkins, and Solman; the other due to Burton) are analyzed. The Burton correction is shown to be the proper way to correct for post-exposure fog. Recent light-latensification experiments by Attridge on Kodak Blue Brand x-ray emulsion utilized the Farnell-Jenkins-Solman correction. These data arc reanalyzed using the Burton correction, showing a maximum sensitivity increase upon latensification of-0.25 log E. This result is in excellent agreement with the predictions of the nucleation-and-growlh model for Atlridge’s experimental conditions.
