Photography is used to preserve memories of favorite times, to capture special moments, to tell stories, to send messages, and as a source of entertainment. Photography as a usable process goes back to the 1820s with the development of chemical photography. Photography is a unique and creative medium of self-expression. Throughout the history of photography, technological advances in optics, camera production, developing, and imaging have had an effect on the way people view images. 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. If photography is authentically art, then photography in the context of art would need redefinition, such as determining what component of a photograph makes it beautiful to the viewer. When it comes to taking quality photographs, you need to know what lenses you should use, and when you need to use them. 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. The commercial photographic world could include Advertising photography. These are photographs made to illustrate and usually sell a service or product. Photography can also be viewed as a commercial and artistic endeavor. Even after color film was readily available, black-and-white photography continued to dominate for decades, due to its lower cost and its "classic" photographic look. The technology has improved so rapidly that one of Kodak's film cameras was discontinued before it was awarded a "camera of the year" award later in the year.
