DESC: With the Canon AW-DC30 waterproof case for the PowerShot SD200 or SD300, you can use your digital camera to take underwater photos at depths of up to 3 meters (10 feet). And 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 Sea & Sea, Ikelite or Sunpak.
