翻开摄影史我们可以了解到,照相机的前身是绘画用的暗箱。画师为了真切的描绘风景和人物,用暗箱勾勒出底稿再细致上色。依据绘画的对象、场合不同,绘画暗箱形制、构造各异,但是基本的原理是一致的,都是一个成像镜头镶嵌在密不透光的盒子上。今天我们使用的数码相机的基础构造也是如此。照相机的机身是主体框架,装载、支撑、连接各部分元件。不同画幅、功能的照相机,结构、尺寸差别巨大,但其核心部分都是一个不透光的盒子,要确保必要的光线有控制地进入并投射在成像介质上形成影像。
Open the history of photography we can understand that the camera’s predecessor is a black box for painting. Painter in order to truly describe the scenery and characters, with black-out sketched out the script and then carefully colored. Depending on the object of the painting, the occasion is different, the painting black box shape, different structures, but the basic principle is the same, are an imaging lens mounted in a tight opaque box. The same is true of the basic construction of digital cameras we use today. The camera’s body is the main frame, loading, support, connecting the various components. Different format, function of the camera, structure, size, huge difference, but its core is an opaque box, to ensure that the necessary light control and enter the imaging medium to form images.
