Designed with the sophisticated photographer in mind, the G1 allows you to manually control every aspect of your shot (as well as offering a variety of AE modes) to allow unfettered creativity.
While the G1 offers a variety of automated settings to handle many of the variables that go into taking a great picture, advanced photographers may wish to take some or all of these into their own hands. In addition to manual focus, the G1 offers a variety of exposure control modes that allows the user to dictate the aperture or the shutter speed, or both. White balance can also be preset or customized via a white-paper shooting feature. The range of control available in the G1 allows maximum creativity for sophisticated photographers.
