Learn how to build an inexpensive waterproof housing for your camera that allows you to take high-quality underwater photos. All you need are a couple store-bought items, and a splash of imagination!

Here are some quick tips to remember when using amateur underwater housing for your camera.

Shoot in bright light (the harsher the better).

Shoot as wide as you can (since water magnifies).

Shoot as close as you can (since water’s never 100% clear).
