补充资料:延时摄影
长时间定时定格延时拍摄。亦称低速摄影或定时定格摄影、"缩时"摄影。定时、间断记录并以明显变化的影像再现景物缓慢变化过程的手段。譬如花蕾的开放约需3天3夜,即72小时。每半小时拍它的一个画幅,以顺序记录开花动作的微变,共计拍摄144个画幅,再通过放映机按正常频率放映(每秒24幅),在6秒钟之内,重现3天3夜的开花过程。
延时摄影需用能定格拍摄的摄影机,延时自动控制器、稳压电源、照明灯、光照灯(代替太阳光照),在恒温摄影室内拍摄。拍摄时还应注意温、湿度以及光照时间长短对被摄体的影响,并控制好"镜头"的动作节奏感。
自然界中如细胞分裂、卵的孵化、日蚀月蚀、云彩变幻、天文、地理等多种题材的拍摄,经常采用延时摄影,以便积累科研资料。
