People taking picture everyday. Maybe thousand of hundred picture are spread online in internet. But most people don't really understand how camera actually work.
Principle of camera can be analogy as a eye. We see thing everyday. Just like camera most people also don't understand how eye see thing. Even I don't really know how. The main thing is that eye capture light and lens control how much light get into the eye, and information from the eyes transfer into the brain.
Alright, lets just leave the eye and back to camera. Camera working on this principle. Unlike with organic part, camera started with a simple box. Around 400BC to 300BC, ancient philosophers of more scientifically advanced cultures (such as China and Greece) were some of the first peoples to experiment with the camera obscura design for creating images. The idea is simple enough—set up a sufficiently dark room with only a tiny bit of light entering through a pinhole opposite a flat plane. The light travels in straight lines (this experiment was used to prove this), crosses at the pinhole, and create an image on the flat plane on the other side. The result is an upside-down version of the objects being beamed in from the opposite side of the pinhole—an incredible miracle, and an amazing scientific discovery for people that lived more than a millennium before the “middle ages.”
From this camera obscura design, the art of capturing "moment" now even grower than before. To understand modern cameras, we can start with the camera obscura, leap forward a few thousand years, and begin talking about the first pinhole cameras. These use this same simple “pinprick” of light concept, and create an image on a plane of photosensitive material—an emulsified surface that reacts chemically when struck by light. Therefore the basic idea of any camera is to gather light, and record it on some kind of photosensitive object—film, in the case of older cameras, and photo sensors, in the case of digital ones.
Now camera has become digital and work more conventionally than thousand of years ago. With a touch of a button, you can take a picture of everything. Now everyone can be a photographer even if they don't realize it.
