With the popularity of cameras, it has become easier than ever to capture the moments in your life. Learn how to take great pictures, along with tips for those trickier shots.

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 asphotographic film.[1]

Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which iselectronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically “developed” into a visible image, either negative or positivedepending on the purpose of the photographic material and the method ofprocessing. A negative image on film is traditionally used to photographically create a positive image on a paper base, known as a print, either by using an enlarger or by contact printing.

Photography is employed in many fields of science, manufacturing (e.g.,photolithography) and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication.
