What camera do you miss trees with?

No matter what grade of camera, no matter what theme, as long as the camera can adjust the focal length, the subject can be photographed clearly; Even some cameras with wide-angle lenses can take clear photos at infinity after 1.2~ 1.5 by using hyperfocal distance's principle. Camera, full name camera, is a kind of equipment that uses optical imaging principle to form images and record images with negative.

A camera is an optical instrument used for photography. After the light reflected by the photographed scene is focused by the photographic lens and the shutter controlling the exposure, the photographed scene forms a latent image on the photosensitive material in the camera box, and the latent image is developed to form a permanent image. This technology is called photography. First, the traditional camera: an opaque box is the camera. A camera is a photographic equipment that uses photographic film to shoot a scene. Its invention took a long time.

China has a long history in studying light and images. As early as more than 400 years BC, China's book Mo Jing recorded in detail the straight-line advance of light, the reflection of light and the imaging phenomena of plane mirror, concave mirror and convex mirror. In the Song Dynasty, Shen Kuo's Meng Qian Bi Tan (103 1 to 1095) also described the principle of pinhole imaging box in detail.

/kloc-During the Renaissance in the 6th century, an "imaging camera box" for painting appeared in Europe.

1839 On August 9th, the French painter Daguerre announced his invention of silver plate photography, which gave birth to the world's first portable wooden box camera.

184 1 year, optician Vogeland invented the first all-metal camera. The camera is equipped with the world's first photographic lens with the maximum phase aperture of 1: 3.4 designed by mathematical calculation.

1845, German von Martens invented the world's first 150 turning point. 1849, Davie-Blue Scott invented a stereo camera and a two-lens stereo observation mirror. 186 1 year, physicist Maxwell invented the world's first color photo.

1866, German chemist Short and optical scientist Arjun invented barium crown optical glass in Zeiss Company and produced positive photographic lens, which made the design and manufacture of photographic lens develop rapidly. 1888 Kodak company produced a new type of photosensitive material-soft and windable "film". This is a leap in photosensitive materials. In the same year, Kodak invented the world's first portable square box camera with film.
