Who invented the earliest camera?

Daguerre (1 787165438+1October18-1851July1) is a French artist and chemist, who is famous for inventing the silver plate photography. Daguerre was born in Valle de Voize, ile-de-france. I have studied architecture, drama design and panoramic painting, and I am especially good at stage fantasy production, so I have a good reputation.

1839, Daguerre made the first practical silver camera. Its basic idea is to expose a copper plate with silver iodide on its surface, then steam it with mercury vapor and fix it with salt water, so that a permanent image can be formed. Later, Daguerre made the world's first camera according to this method. Daguerre photography is the first successful photography method in the world.

Advantages and disadvantages of digital camera

superiority

1. You can see the picture immediately after taking a picture, which provides the possibility of remaking the dissatisfied work immediately and reduces the occurrence of regrets.

Just pay for those photos you want to develop, and other unnecessary photos can be deleted.

3. Color reproduction and color range no longer depend on the quality of the film.

4, the sensitivity is no longer fixed by the film, and the photoelectric conversion chip can provide a variety of sensitivity choices.

5, the product structure is relatively simple, the appearance is more exquisite, and the product is more and more portable.

6. The digital camera is simple, clear and easy to use.

disadvantaged

1. Due to the conversion between imaging elements and image processing chips, the imaging quality is less layered than that of optical cameras.

2. Due to the different technologies of image processing chips from different manufacturers, the colors of the imaged photos are different from the real ones.

3. Due to the lack of core technology in China, the later use and maintenance costs are high.
