If you’re going to the beach or pool this summer, don’t limit your picture-taking to the land. Invest in an underwater housing and take the plunge without getting your camera wet. Here are a few things to keep in mind before you go under:

• Stay close to the surface, where the light is best.

• If your camera doesn’t have an underwater scene mode, use the cloudy white balance setting. This will help offset the blue tint of the water.

• Turn on image stabilization; it will help keep your shots sharp, even while you’re floating.
