1.原物大拍摄的原理根据摄影成像原理,来自被拍摄目标物的光线通过镜头,最终会聚在胶片平面上,形成目标物的影像。照相机的镜头相当于一个正透镜,其成像光路如图1所示:
1. The principle of the original big shot According to the principle of photographic imaging, the light from the target is passed through the lens and finally converges on the film plane to form an image of the target. Camera lens is equivalent to a positive lens, the imaging light path shown in Figure 1:
