The G1's remaining exposure controls, accessible via one of the on-camera buttons or through the Record menu, are quite extensive. Lock function allows you to lock the flash exposure setting for one specific subject in the frame. They include Pan Focus, Portrait, Landscape, Macro, Night Scene, Black and White, Stitch-Assist, and Movie. Pan Focus, Portrait, and Landscape all make automatic camera adjustments to optimize shooting under specific conditions. For example, the Pan Focus fixes the lens focal length to its widest angle setting and hyperfocal distance to give you maximum shutter speed and depth of field to cover unpredictable subject movement.
Landscape mode slows the shutter speed and maximizes depth of field.
Night Scene mode illuminates your subject with flash and uses a slow shutter speed to evenly expose the background. The Stitch-Assist mode is Canon's answer to panorama mode, in which multiple, overlapping images can be captured horizontally, vertically, or in a clockwise grouping. Movie mode allows you to capture up to 30 seconds of moving images and sound at approximately 15 frames per second. Continuous Shooting mode captures multiple, successive still images, at about 1.7 frames per second, as long as you hold down the shutter release. A USB cable is provided with the camera for speedy connection to PC or Macintosh computers, and two software CDs offer an impressive selection of utilities.
