Photography is the art, science and practice of creating durable images by recording light or other electromagnetic radiation, either by way of chemical light-sensitive material such as photographic film, or electronically via an image sensor. [1] Typically, the lens used for the light reflected or emitted by an object in a real image on a light sensitive surface targets at the camera during the exposure time. The results of an electronic image sensor is an electrical charge at each pixel is processed electronically and stored in a digital image file for reporting or processing agents.

Result in a photographic emulsion is an invisible latent image, which is then chemically developed into a visible image, negative or positive, depending on the purpose of the photographic material and processing. A negative image on film is traditionally used photography to create a positive image on the paper base, known as a print or print using the enlarger or by contact.

The photographic image snapshotis one of the most widely distributed in existence. [2] The picture is one of the few to show, as the astronauts had the Sun behind them when they are fully enlightened earth image. For the astronauts, the Earth has the appearance and size of the glass marble, hence the name.

First success occurs reproduce images without a camera when Thomas Wedgwood, the famous family of potters, obtained copies of paintings on leather with silver salts. Since he had no way to confirm this reproduction, still they will darken in the light and in the dark room so had to check to be stored.

Renaissance painters use the camera obscure which, in fact, gives the optical rendering in color that dominates Western Art. Camera obscure literally means “dark chamber” in Latin. It is a box with a hole in it that allows light to pass through and continue to create an image on a piece of paper.

The camera has a long and distinguished history as a means of recording phenomena from the first use by Daguerre and Fox Talbot, such as astronomical events for macro photography and the larger specimens. The camera also proved useful in recording crime scenes and the scenes of accidents, such as the Wootton bridge collapse in 1861. The methods used in analyzing photographs for use in legal cases are collectively known as forensic photography.

In 1853, Charles Brooke had the technology for automatic registration of instruments created by photography. This instrument related information through the automated process of photography including barometers, thermometers, psychometric, and magnetometers
Photography has become ubiquitous in recording events and data in science and engineering, and at crime scenes or accident scenes. This method is very spacious with other wavelengths, such as infrared photography and ultraviolet photography and spectroscopy. This method was first used in the Victorian era and developed much further since then.
