Automatic camera and manual camera:
Automatic camera is always easier to use because it has the automated settings predefined in them and hence it consumes less amount of time. The paparazzi often use automated mode because they have to time to dig stuffs rather than wasting their time upon manual setup.
Manual cameras are adjusted according to the lighting and according to the background. If these set up are done already then it would be rather easy to use. Hence most people prefer automatic cameras
