当胶片冲洗后,我们有时会发现胶片上有闪电状或树枝状黑色条纹,这是静电留下的痕迹。这些痕迹既破坏了画面的美感,又给工作带来麻烦。胶片上静电产生的原因是多方面的,但我认为拍摄后产生静电的主要原因是:胶片从片盒里卸下的瞬间产生的。因为,片盒里两边各有一块压片玻璃,在温度、湿度等自然因素的作用下,胶片与玻璃产生粘连,当把拍完的胶片取出时,两个粘连的面就产生一个摩擦力,摩擦起电。同时在胶片上留下了静电痕迹。
When the film is washed, we sometimes find lightning or dendritic black stripes on the film, which are traces of static electricity. These traces not only undermine the beauty of the picture, but also to bring trouble to work. There are many reasons why static electricity is generated on the film, but I think the main reason that static electricity is generated after filming is the moment when the film is unloaded from the film box. Because, on both sides of the film box has a tablet glass, in the temperature, humidity and other natural factors, the film and glass adhesion, when the finished film removed, the two adhesion surface to produce a friction, Friction electrification. At the same time left in the film on the traces of static electricity.
