Investigation of apparent kinetics of nickel physical development: two-stage amplification

Abstract

The paper reports on an investigation of the apparent kinetics of two-stage amplification of nickel physical development using ‘Lucky’ black-and-white cine positive film 5141 made by the Lucky Film Company of China. The factors affecting the kinetics are found and the design of a method (the light density method) for determining the kinetics is discussed. The results show that the light density method can be used to investigate the apparent kinetics of nickel physical development in a certain light density range. The method is simple, fast and cheap. When the results of calculating the apparent rate of nickel physical development are compared with experimental results, a relative error of less than 7 per cent is found. The results show that the equation is quite accurate.
