In this picture you can see there is a four-way skydive, four people flying together, and on the left hand side it's the camera flier with the camera mounted to his helmet so he can film the whole jump, for the film itself and also for the judging.
从这张照片你可以看到 这个是四人式跳伞， 四个人一块儿下落， 左手边的跳伞员负责摄像机 他的头盔上设有一个摄像机 所以他就可以拍摄整个跳伞过程， 拍摄的目的不仅仅是为了拍摄还为了事后对录像进行分析。
