The aesthetics of photography is a matter that continues to be discussed regularly, especially in artistic circles. Fashion and glamour photography usually incorporates models. 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. Photography has many uses for both business and pleasure. 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. 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. Digital photography has also been adopted by many amateur snapshot photographers, who take advantage of the convenience of the form when sending images by email, placing them on the World Wide Web, or displaying them in digital picture frames. 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.
