The history of camera, from the big-bulky cameras to high-end DSLRs.
Well, the dawn of modern cameras has just began. Many types and kinds of cameras are emerging from our modern-day technology. You name it, whether Nikon, Canon, Kodak, Sony a counting..
The first permanent photographwas made in 1826 or 1827 by Joseph Nicéphore Niépce using a sliding wooden box camera made by Charles and Vincent Chevalier in Paris. Niépce built on a discovery by Johann Heinrich Schultz (1724): a silver and chalk mixture darkens under exposure to light. While this was the introduction of photography, the history of the camera itself can be traced back much further. Photographic cameras were a development of the camera obscura, a device dating back to the Book of Optics (1021) of the Iraqi Arab scientist Ibn al-Haytham (Alhacen),[1] which uses a pinhole or lens to project an image of the scene outside onto a viewing surface.
Before the invention of photographic lapel processes there was no way to preserve the images produced by these cameras apart from manually tracing them. The earliest cameras were room-sized, with space for one or more people inside; these gradually evolved into more and more compact models such that by Niépce's time portable handheld cameras suitable for photography were readily available. The first camera that was small and portable enough to be practical for photography was built by Johann Zahn in 1685, though it would be almost 150 years before such an application was possible.

That was a major leap in the camera history. Our echology in kowing these kinds of thigs just emerges from our day to day experieces in the dawn of digital photography.
What the heck is PHOTOGRAPHY?
Photography is the process of recording pictures by means of capturing light on a light-sensitive medium, such as a film or electronic sensor. Light patterns reflected or emitted from objects expose a sensitive silver halide based chemical or electronic medium during a timed exposure, usually through a photographic lens in a device known as a camera that also stores the resulting information chemically or electronically. Photography has many uses for both business and pleasure. It is often the basis of advertising and in fashion print. Photography can also be viewed as a commercial and artistic endeavor.
The word "photography" comes from the French photographie which is based on the Greek φώς (phos) "light" + γραφίς (graphis) "stylus", "paintbrush" or γραφή (graphê) "representation by means of lines" or "drawing", together meaning "drawing with light." Traditionally, the product of photography has been called a photograph, commonly shortened to photo.
