利用自然光做面光源拍照凸面客体上痕迹

Using Nature Light as Surface Lamphouse to Photo Imprint on the Convex Object

对柱面、球面等凸面物体上痕迹的拍照,一直是刑事照相专业的难点之一。利用自然光做面光源配光,在凸面客体上形成大于痕迹面积的光斑,进行定向反射照相,可以有效解决部分拍照凸面客体上痕迹难题。

To photo imprint on the convex object such as cylinder or sphere is the difficulty of forensic photography,the directional reflex photo by using nature light as surface lamphouse to form a facula bigger than the area of convex object can effectively solve this problem.
