If you are skilled with a camera, and are motivated to earn your own money in this way, you can be a successful photographer, even on a part time basis. Color photography was first explored beginning in the mid 1800s. Photography can also be viewed as a commercial and artistic endeavor. You should learn about lenses, exposure, and other basic techniques used in the many different types of photography. Modern digital cameras have comparable noise/grain at the same ISO as film cameras. 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. At the highest-end, some digital cameras are nothing but a sophisticated light-sensing unit. Instant cameras and commercial film development at reasonable prices helped cameras become a part of almost every household. 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. 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.
