Since it was difficult to land already halfway to take good pictures, there will be underwater well not be better (I did not try). Although of course you can not expect an excessive amount of a camera in this price range, so it was for the price then too little. In particular, because the videos were so bad in daylight, that even my 4 year old phone better videos (and photos) makes.
Perhaps I had caught a bad device. If so, and someone wants to buy the camera, and keep those there on Youtube a video where a few tips are included, how best to adjust the camera. Simply "INTOVA IC 12 Product Presentation" Search. Although for the IC 12, but much will be no different. There is no fact in both models an underwater mode.
