Use a waterproof housing when taking pictures underwater.
In order to bring back images from an underwater world, you will need a camera and a protective shield to protect your device against water damage and pressure. Canon manufacturers an array of cameras from point-and-shoot to film to DSLR (Digital Single Lens Reflex) cameras. If you are looking to take underwater pictures on your next diving exploration, Canon's underwater housing systems can be just the accessory you need to capture that memorable underwater image.
Instructions
1. Purchase an underwater housing for you Canon camera from an online camera retailer or local electronics store. Canon produces underwater housing for some point-and-shoot cameras as well as its DSLR cameras. To find a compatible underwater housing, visit the Canon Underwater Housing Compatibility Chart.
2. Prepare the camera for taking underwater pictures by making sure the battery is fully charged, that there are no cracks in the housing and that the memory card has enough storage space. If you are using film, make sure the film is loaded properly and the roll is fresh, not expired.
3. Perform a few test shots on dry land to make sure the buttons and flash mechanism are in working condition and are accessible through the housing.
4. Take underwater pictures much as you would take pictures on dry land. If you are using a DSLR, look through the viewfinder and take the picture. If you are using a point-and-shoot, see the image on the preview screen. If your underwater housing is made specifically for your camera model, you should have no problem looking through the viewfinder or screen. If your housing is universal, you may have to adjust the camera in order to get a good view before taking a picture.
5. Select the type of shot you want to capture, such as macro or wide angle shots. Wide angle shots are mainly for capturing a large amount of area with less emphasis on the details but more on the big picture. According to Canon, you always want to keep the water color blue by setting the "White Balance" and choosing the options "Daylight" or "Cloudy" depending on the water depth and sunlight conditions. Macro shots are for small underwater close-ups with a minimal distance in between the camera and the subject. To focus on close objects, hold the shutter button halfway to perform an automatic focus before taking the picture.
