With the Canon WP-DC34 waterproof case for the Canon PowerShot G11 & G12, you can use your digital camera to take underwater shots at depths of up to 130' (40m). Of course it's also ideal for taking worry-free pictures in the rain, at the beach, or on the ski slopes.
You can use your camera's internal flash for lighting purposes. Or, use the internal flash to trigger a slaved external strobe like those made by Fantasea, Sea & Sea, Ikelite, or Sealife. The camera has an underwater white balance setting for available light photography.
