Practical Aspects of Reciprocity-Law Failure
The occasional failure of sensitometric data to provide a reliable indication of the practical performance of photographic materials is usually attributable to the failure of the reciprocity law. The effect of reciprocity-law failure on the characteristic D-log E curves of various films is shown graphically. The influence of developing time and of the temperature of the film on the effectiveness of exposure at various intensity levels is discussed. Certain generalizations are made about the failure of the reciprocity law which may be helpful in reconciling differences between laboratory measurements and the results obtained in motion picture practice.
