screwy idea I have about saving my camera from flooding

How about a regulator that would keep the housing pressurized underwater. You would only need a slight positive pressure. Any leaks would blow bubbles.

This system actually existed back in the cool days. Just about every "pro" system had the little regulator and air supply. This system was always "on", keeping the internal pressure more or less equal to the surrounding pressure. There was an exhaust valve to vent air as you ascended. In theory, you could take such a housing (perhaps made of 1/16 inch plexiglass) down to 1000 feet or more without it imploding. Eventually people realised that few divers go that deep and o-rings are cheaper and more reliable.

Archie,

This is how Aggie jokes get started!
