I bought my wife a canon S100 2 months ago and we are planning a trip to the panama city beach in about a month. She wanted to buy me an underwater camera when we went but i said lets just buy a case for yours. Case will not be used in very deep water as i dont scuba dive, maby 20 feet deep or so around the jetties and the beach. Also any tips on camera settings, seems like i read that there is an underwater mode for the S100 or do i shoot in RAW mode and post process.
