摘要: 本文作者曾经通过评估成像效率的当前状态和理论极限之间的差距以及分析产生此差距的原因预测过卤化银照相材料的未来发展.本文描述了采用上述的方法来评估和分析彩色胶片与数字照相的现状.经预测在未来前者成像效率的改进余地会远大于后者.

关键词: 成像效率, 卤化银乳剂, 彩色胶片, CCD, 数字照相

Abstract: The present author has ever predicted the future of silver halide photographic materials by evaluating the distance between the present state and theoretical limit of the efficiency of image formation and analyzing the causes for it. This paper describes the result of the application of the above stated method to color films and digital still cameras at the present. It was predicted that the room for the improvement of the efficiency of image formation of the former would be much larger than that of the latter in the future,and that the former will continue to lead photography.

Key words: efficiency of image formation, silver halide emulsion, color film, CCD, digital still camera
