INTRODUCTION:
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.

Origins and Development

The word, photography combines the Greek root phtos () and the genitive version of phs (). The word also includes the Greek word for light. It ends in the word graph (), which refers to the act of drawing lines. The composite of the word photography is, therefore, drawing with light (Corner, 2007). By 1834, the word was in use even before the process had been fully developed. For example, the French Painter, Hercules Florence, referred to it in his writing. Moreover, the German astrologer, Johann von Maedler, published an article in 1839 referring to photography. Sir John Herschel also used the term in his correspondence at the Royal Society. This shows that as far back as the beginning of the 18th Century, there were references to this process. Our modern conceptualization of photographs are those grainy images that attempted to capture cameos of Victorian life. The world was understandably fascinated by something that seems capable of storing memories in a tangible form. Gradually, the still images became unsatisfactory, so further development in videography was a consequence of the worlds awareness of photography. Apparently, the etymology of photography indicates that people had an early notion of the possibilities of the art and science of photography. However, it was only in the 1830s that they started to actively find ways of making this conceptualization a reality in a tangible product that could be marketed.
