In the 1880s, Marey turned his attention to the tricky analysis of bird flight, photographing sequences of herons and cockatoos.

时间转到19世纪80年代，马雷也把注意力转移到分析棘手的鸟类飞行姿态上。他拍摄了苍鹭和鹦鹉的飞行序列照片。

Marey invented a technique called "chronophotography" that captured the stages of movement on a single photographic plate, with multiple exposures per second so that the moving figures overlap.

马雷发明了一种叫做“chronophotography”的摄影方法，也就是通过多重曝光在同一张底片上连续捕捉某个动作的不同阶段，让变化的对象不断重叠。
