电子闪光灯是新闻、科研和生活摄影中不可缺少的照明光源之一。为了使光照均匀,减少反差,需要双灯或多灯同时闪光。利用一只或两只光同步分灯和一只普通电子闪光灯可组成多灯照明系统,其方法如图1所示。这一系统的工作过程是这样的:当用摄影机摄影时,闭合上摄影机的联闪开关,使主灯闪光(摄影机和主灯之间是线同步的)。在主灯闪光照明目标的同时,光照射到分灯的光敏元件,分灯被光触发后对目标同步闪光。由于光电控制反应速度极快,延时短于
Electronic flash is one of the indispensable lighting sources in news, research and life photography. In order to make the lighting uniform and reduce the contrast, it needs two or more lights to flash at the same time. The use of one or two light sync lamp and an ordinary electronic flash can be composed of multi-lamp lighting system, the method shown in Figure 1. The system works like this: When taking a picture with a video camera, close the camera’s jog switch so that the main light flashes (the line between the camera and the main light is line-locked). In the main light flash lighting target at the same time, the light shines on the light-sensitive components, sub-light is triggered by the light flash synchronization of the target. As the photoelectric control response speed, delay is shorter than
