Under water photos

These were taken with a little Sony Cyber-shot set on full auto. It was enclosed in a cheap waterproof enclosure that is little more than a plastic bag with an adaptor to accommodate the protruding lens. There are waterproof hard-cases available and they are undoubtedly better but they cost a lot.
It's quite difficult seeing the image on the viewfinder screen when under water with the sun above and with the setup I was using the pop-up flash couldn't be used.
The photos below have all been cropped and slightly brightened as they were a tad under exposed.

 

Great pictures Dave. There's some amazing creatures and wonderful colours.
