Capturing and Presenting Imagery Most lay people see the results of photography, but are not conversant with the process through which the images are created. Note from the outset that photography is a multidisciplinary endeavor that could be qualified as both an art and a science.

The technical definition is the practice of creating, developing, and presenting durable images through recording electromagnetic radiation and light (Newhall, 2009). Photography can be done using electronic means by way of an image sensor. Alternatively, it can be achieved through chemical means by way of a light-sensitive material. This material is photograph film in industry parlance. The photographer may use a pair of lens to focus the light naturally emitted by objectives. These are then placed onto a real image, which sits on the light-sensitive material. That surface typically sits within a camera. Photography requires a fixed time exposure under controlled conditions. There is an alternative of using electronic image sensors. These will produce an electrical charge hosted on each pixel. Using modern equipment, it is possible to process and store that information on a digital image file. Photography has been noted for its ability to store and preserve memories fixed within a set of images of varying quality. After the first stage of photography, there is a stored data set on a photographic emulsion. This is in an invisible latent image. This image is then developed, using chemical means so it becomes visible. The industry designates the image as being positive or negative. This classification depends upon the purpose for which the photographic material will be used, as well as the method of processing used. Typically, a negative image on film is used to create a positive image on a paper base. This is a print. It can be achieved by using contact printing or a designated enlarger. Applying photography, today, remains wide because of the need to preserve memories. You are likely to find photographers working in manufacturing, photolithography, forensics, medicine, research, business, and entertainment. It is the principle from which emanates the subfields of video production, filming, modern art, and other forms of mass communication. The democratization of photography through the standard camera has meant virtually everybody can have access to it.
