感光胶片的静电放电现象,使显影加工后的画面上,产生树枝状或霉斑状灰雾,这在气候干燥季节尤为多见。随着胶片感光度的不断提高,以及显影加工的机械化、高速化,这一问题更为突出。本文就静电灰雾的产生及其防止方法,作一扼要介绍。

Photographic film electrostatic discharge phenomenon, so that the processing of the picture after the screen, resulting in dendritic or mildew-like fog, which is particularly common in the dry climate. With the continuous improvement of film sensitivity, as well as the development of mechanization, high-speed, this issue is more prominent. This article on the generation of electrostatic fog and prevention methods, make a brief introduction.
