Porth yr Ogof cave entrance

Experiments with split level photography at the entrance of Porth yr Ogof, a cave on the southern edge of the Brecon Beacons National Park in South Wales. It was a very dull, rainy day. Dressed in a 7mm wetsuit with a hood, mask and snorkel I spent the afternoon swimming around the cold pool at the cave entrance with my digital SLR in its underwater housing. The housing was attached to a tripod and sank quite well - unlike me. I had a 4-kilo weight belt but it wasn't really enough to be able to sink easily and look through the viewfinder - my underwater handstands amused the local cavers....
