Things You'll Need
Instructions
Purchase a commercially made rain shield for your camera equipment. These rain shields are made for professionals who have to take pictures in adverse weather conditions. They create a moisture-proof barrier around camera equipment while still providing easy access to the sensors and dials for photographers.
Protect smaller camera equipment and parts when not in use by storing them in gallon-sized freezer bags. These bags can be sealed to prevent moisture from reaching their contents.
Create a homemade vapor shield around your camera by cutting a small hole in the end of a trash bag. Tape this hole around the end of your lens tube with masking tape. Then close the rest of the camera by wrapping the trash bag around it. You can access your camera by unwrapping the bag just enough to reach the camera. This will shield the delicate sensors from salt spray.
Invest in an underwater housing for your camera. This type of housing locks out all moisture, allowing you to use your camera underwater. Above the water, it will keep out salt spray.
