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 .
The authors have previously predicted the future development of silver halide photographic materials by assessing the gap between the current state of the imaging efficiency and the theoretical limit and by analyzing the causes for this discrepancy.This paper describes the methods used to evaluate and analyze color film and digital photography The prediction of the future in the former imaging efficiency improvement will be much greater than the latter.
