This document discusses various camera modes and their functions. It begins by explaining automatic modes like auto, portrait, landscape, macro, sports and night modes. It then covers semi-automatic modes like aperture priority and shutter priority that allow the user to control either aperture or shutter speed while the camera sets the other setting. Finally, it discusses manual mode where the user has full control over aperture, shutter speed, ISO and white balance settings. It provides examples to illustrate how different modes and settings can be used creatively.
