摘要
密度测量是黑白胶片感光测定的重要环节。阐述了密度测量影响因素 ,并在此基础上 ,论述了密度测量的几何模式和光谱条件 。
The determination of transmission density is a important step in sensitometry of balck and white photographic films.the paper explains geometric conditions and spectral conditions for measuring transmission density.methods and principle to choose density form during measuring transmission density are also pointed out.
