摘　　要：要创作出一部高质量的黑白影片,除了需要有高超的摄影技巧外,后期的洗印加工也是致关重要的。如同彩色片的后期洗印加工一样,黑白片也必须根据洗印厂的设备等实际情况,为其建立一个最佳的加工条件,以确保影片质量。本文根据现行加工的实际情况从底片格码值的变化对胶片感光度、曝光宽容度和画面影调的影响等,较详细的探讨了黑白电影底片和正片洗印加工控制技术。To create a high quality black-and-white film, post-processing of laboratories is of crucial importance in addition to superb shooting skills. Same as color film, post-processing of laboratories in black-and-white film must be based on actual plant equipment for the establishment of an optimal processing condition to ensure high video quality. The process control techniques on the black-and-white motion picture negative and positive films were discussed in details, especially the control of impacts of the negative film gamma value change on the film sensitivity speed, exposure latitude and picture tone based on the actual current processing situation.
