    • A copy stand for supporting a camera having a built-in flash device to photograph a subject in an exposure area. The stand comprises a continuous sheet of paper board folded and coupled to itself to form a generally tubular section adapted to surround the subject in the exposure area and establish the position of the subject relative to the camera and flash. The tubular section includes a baffle, which blocks direct flash illumination of the exposure area, a first diffuse reflector, which directs flash illumination around the baffle and toward the exposure area, and a second diffuse reflector on the opposite side of the exposure area from the first reflector. The second reflector redirects illumination from the first reflector back toward the exposure area, thereby illuminating the subject area from multiple directions.
    • 用于支持具有内置闪光装置的相机的复印台,以在曝光区域拍摄被摄体。 支架包括折叠并连接到其自身上的连续纸板,以形成适于在曝光区域中包围被摄体的大致管状部分,并建立被摄体相对于照相机和闪光灯的位置。 管状部分包括阻挡曝光区域的直接闪光照明的挡板,引导围绕挡板并朝向曝光区域的闪光照明的第一漫反射器,以及在曝光区域的相对侧上的第二漫反射器 第一反射器 第二反射器将来自第一反射器的照明反射回到曝光区域,从而从多个方向照射被摄体区域。
