Brief History of Photography:
The whole technique of photography can be broken down into two simple ideas. One: to capture the light that comes from any one of the scenes and to reflect on a screen. Two: To capture that reflective view permanently through one.
The first one, as well as the content on the screen, was known long ago. If the front of a dark square box has a hole similar to the hole in a needle, and a white screen is provided on the opposite side of the screen, the opposite view is captured on that screen. If a glass lens could be placed in the hole, then this image would have been clearer, and it was only at that time that people learned about it. But that's it. It takes more than 400 years to discover the technology to capture this image permanently.
