At the highest-end, some digital cameras are nothing but a sophisticated light-sensing unit. When it comes to taking quality photographs, you need to know what lenses you should use, and when you need to use them. Portrait and wedding photography is typically photographs that are made and sold directly to the families of the people in the images. 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. Instant cameras and commercial film development at reasonable prices helped cameras become a part of almost every household. 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. 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.
