With the Canon WP-DC80 waterproof case for the PowerShot SD550, you can use your PowerShot SD550 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 Sea & Sea, Ikelite or Sunpak.
