Extreme photography and underwater photos are great ... as long as your digital camera is useable underwater. If you aren't sure whether your camera is rated as waterproof, read the user manual or visit the manufacturer's Web site. Ignoring the user manual and testing the digital camera in a full bathtub to determine whether it is waterproof is not recommended.
If you'd like to take these types of photos, you'll either need an underwater digital camera, as specified by the manufacturer, or you'll need to purchase an underwater housing for your digital camera. Here are some of the best underwater digital cameras and accessories.
