Photography: Professional Photography Explained - Techniques, Development and Application

Ebook, 2016. — 61 p. Most lay people see the results of photography but are not quite conversant with the process through which the images are created. It is important to 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 that of the practice of creating, developing and presenting durable images through the recording of electromagnetic radiation as well as light. 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 known as photograph film in industry parlance. The photographer may use a pair of lens in order to focus the light that is 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 which is hosted on each pixel. Using modern equipment, it is possible to process and store that information on a digital image file.
