Photography was born in 180. How to review the history of photography through practice?

You can look back at history by shooting. Photography has undergone great changes from its development to the present. Let's talk about the earliest pinhole photography, which appeared very early. At that time, the light shone directly on the film through a pinhole-like hole. This method is simple and clear, and the operation mode is extremely simple, but the mystery of light is not clear.

There is also a kind of silver plate photography, which was invented by a French painter. He realized it by using the principle of water vapor exposure. However, this process takes a long time, about half an hour, but it still saves a lot of time compared with pinhole. The quality of the photos taken by this method is relatively high, the pixels are relatively clear, and it is not easy to fade, but there is a bad place, that is, it cannot be copied.

Let's talk about the silver iodide photographic paper method first. Compared with the first two methods, the biggest advantage of this method is that the time is much shorter. Moreover, it can be copied. At that time, this method was very popular with everyone, especially in Britain, and many people were using it. In fact, people like this photography method mainly because it takes a short time. He mainly used paper as a negative film, then put the paper in salt water and then in the solvent plum, and it was basically formed. This is very close to our current photo development.

Finally, let's talk about our current photography method, which was a SLR camera at that time. As the saying goes, playing SLR for three generations shows that the price of SLR is very expensive. Although expensive, the photos taken by SLR are very clear and beautiful. It can also be seen from the development history of photography that the development history of the world is very fast.
