Experience Level: Point and Shoot - the camera fully automates the picture taking process, you simply press the shutter button. Some predefined scene modes may be available to choose from, but not manual exposure controls.

Serious amateur - the camera may provide automatic settings but also offers manual controls, such as adjustable white balance and shutter speed, as well as manual exposure controls, such as Aperture Priority, Shutter Priority and full Manual Exposure.

Professional - only the best will do, if it is not a high end dSLR you are not interested.
