Do you learn photography from scratch at home during the graduation season of college entrance examination and holidays?

The three-day intense college entrance examination is over, and the middle school era has come to a satisfactory end. Since then, children have begun to mature and step into society.

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.
