what is photography

Photography is the science, art and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film.

The photographic camera was the result of combining many technical discoveries, which probably started with the camera obscura, a box with a hole in it which allows light to go through and create image onto the piece of paper.

 A still camera is an optical device which creates a single image of an object or scene, and records it on an electronic sensor or photographic film. All cameras use the same basic design: light enters an enclosed box through a converging lens and an image is recorded on a light-sensitive medium. A shutter mechanism controls the length of time that light can enter the camera. Most photographic cameras have functions that allow a person to view the scene to be recorded, allow for a desired part of the scene to be in focus, and to control the exposure so that it is not too bright or too dim. A data display, often a liquid crystal display (LCD), permits the user to view settings such as ISO speed, exposure, and shutter speed.

^{This is the kind of camera I'll use to experiment with photography, a semi reflex, which being a good quality camera, with a decent lense, is also a little bit easier to use than a reflex one, because gives you a little less freedom using it. (doesn't have a manual focus, and you can just take pictures looking at the screen, for example)}
