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.
Photography is also a good and convenient way of capuring your present for past. I love this part, because it refreshes our old memories...
The word "photography" comes from the French photographie which is based on the Greek (phos) "light" + (graphis) "stylus", "paintbrush" or (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.
