Shandong graduation photo Competition
Before entering the university, this summer vacation should be regarded as a very important holiday in the life of young students. It is also a long holiday in a year, and many students will choose this prime time to carry out their own activities to enrich themselves.
Many students are interested in photography. Today, I will teach you how a camera records images and tell you the principle of the camera with three pictures.
1, the principle of taking pictures is pinhole imaging.
The painter sat in a dark room with a small hole, tracing the image on the wall. This is the earliest photo.
2. The camera is a small black box, which is used for pinhole imaging.
1. An opaque black box. 2. There is a hole in one side of the box to transmit light. 3. Put a photosensitive film opposite the pinhole.
3. The smart camera we are using now is based on adding accessories.
1. This hole becomes a lens. 2. The black box becomes the camera body. 3. The film becomes a photosensitive element.
