一、拍摄半径物距 1.确定拍摄半径物距的意义拍摄数百人的大型团体照片,需用长条旋转摄影机(以下简称转机)。其操作程序是:首先须按欲拍底片的长度和欲摄总人数的要求,确定出一个较为准确的拍摄半径物距,然后按此物距以转机(即拍摄位置)为中心,划一弧形长线做标记,再以此标记为准,安排被摄队形。这是用转机拍摄大型团体照片,确保主体成象高度达到正常比例的先决条件。不然将会产生中间影象大、两端影象小和把横平直线表现为中间前凸或向后弯
First, the shooting radius object distance 1. To determine the meaning of the shooting radius Object distance Hundreds of large group photos, the need to use long rotating camera (hereinafter referred to as transit). The operating procedure is: First, according to the length of the film to be shot and the total number of people to be shot to determine a more accurate shooting radius object distance, and then press this object to the transfer machine (ie shooting position) as the center, arc Long-term mark, and then mark the subject, arranged for the formation of team formation. This is a prerequisite for photographing large group photos with turning points to ensure that the subject’s image height reaches a normal level. Otherwise it will produce a large intermediate image, both ends of the image is small and the horizontal straight line as the middle of the convex or backward bend
