Photography can also be viewed as a commercial and artistic endeavor. Portrait and wedding photography is typically photographs that are made and sold directly to the families of the people in the images. Some commercial photographers, and some amateurs interested in artistic photography, have been resistant to using digital rather than film cameras because they believe that the image quality available from a digital camera is still inferior to that available from a film camera, and the quality of images taken on medium format film is near-impossible to match at any price with a digital camera. Other commercial photographers, and many amateurs, have enthusiastically embraced digital photography because they believe that its flexibility and lower long-term costs outweigh its initial price disadvantages. 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. With the acceptable image quality and the other advantages of digital photography, particularly the time constraints of vital importance to newspapers, the majority of professional news photographers have begun capturing their images with digital cameras. Color photography was first explored beginning in the mid 1800s. 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.
