Goldfish all gone? Turn that empty tank into an underwater housing
If you have a digital SLR and don't want to blow two grand on an underwater housing, check out the alternative the folks at Digital Camera World came up with. Just put your camera into a clean fish tank, attach a remote shutter release cable, lower the tank into the water, and fire away. Naturally, this only works in calm water, so don't take it into the ocean unless you fancy buying a new camera.
Though the site mentions you have to take a lot of shots and check the results because you can't see through the viewfinder, it's worth pointing out that using an SLR with a swivel screen would allow you to compose while you shoot.
