In addition to the auto shooting mode that allows you to casually take pictures while allowing the camera to take care of all the details, the 1G camera also provides scene modes that accommodate a wide range of subjects and photographic situations. In addition, 3 modes: A (aperture priority), M (manual exposure) and P (program) allow you to enjoy creative photography to its fullest. The A (aperture priority) mode, allows control by setting the camera’s aperture, enabling you to take a picture while keeping the aperture fully open so that the areas around the subject and the background of the subject are blurry. Alternatively, while using the A mode, you can reduce the aperture to create a very long depth of field, so that everything is in focus. It is a very convenient function for underwater photography. The aperture can be set in 12 increments from the narrowest aperture to fully open, thereby allowing you precise control of the exposure.
