Hi guys

Im looking to get good advice on getting a digital camera for underwater use. I need the camera to be good in and out of the water, and the housing to be good too. I like the sony cyber shot or cannon ixus-how do these perform?

Is it possible to put the red filter on etc..
and on that note who knows what can be done to excessive "blue" images to replace the red, i dont think much can be done huh?

thanks
