Digital photography was used in astronomy long before its use by the general public and had almost completely displaced photographic plates by the early 1980s. Photography can also be viewed as a commercial and artistic endeavor. It is important to note that the differences between film and digital photography are far less significant than the differences between painting and film photography. The commercial photographic world could include Advertising photography. These are photographs made to illustrate and usually sell a service or product. At the highest-end, some digital cameras are nothing but a sophisticated light-sensing unit. Fine art photography includes photographs made to fulfill a vision, and reproduced to be sold directly to the customer. Landscape photography are photographs of different locations often made to be sold to tourists as prints or postcards. Currently digital photography, disposable cameras and even camera-phones continue to make photography part of our lives. Color photography was first explored beginning in the mid 1800s.
