The Canon waterproof case protects your camera and keeps it dry as you dive in the water. It allows you to take underwater shots effortlessly with its designated buttons that connect to your camera’s, as well as a flash diffuser to ensure your flash is controlled. The WP-DC55 case (as seen above) is made specially for Canon PowerShot G7 X Mark II, a compact camera that is lightweight, easy to control, and produces amazing results.

1. Open the case

The case is locked for extra protection and only opens from the side. To open, push the yellow tab up and then lift the lock. It may take several tries to get used to the motion but that is how the case keeps your camera dustproof and waterproof.

2. Clean thoroughly

You would want to make sure that there is no hair, sand, dust or other visible particles in your underwater case. Use a piece cotton bud with some water or lint-free cloth to clean the inside of the case as well as its rim.

3. Grease the O ring

The O ring is crucial to keeping your case airtight. Carefully apply the silicon grease that comes with the Canon underwater case to the O ring before fixing it into the rim to create a waterproof seal.

It is recommended to have a rough idea of what you’re going to shoot and adjust your camera settings accordingly before fixing the camera into your underwater case.

5. Test all the buttons

Once the underwater case is tightly sealed, press on every single button to make sure that they all work. You can also use this opportunity to familiarise yourself with the various buttons, and further adjust your camera setting.

6. Fix the flash diffuser

The diffuser is an important element for your underwater photography. One of the major problems when shooting underwater is backscatter, where light is being reflected off the particles from the flash into the lens, causing distracting white specks. To prevent that from happening, use a diffuser to reduce backscatter in your photos.

7. Attach the lanyard or bungee cord

A lanyard is used to secure the camera to yourself so that it will not float or sink away while you are underwater. Everything is different from being on land so securing your camera is more than just a strap over your neck.

Alternatively, use a bungee cord and attach it to your Buoyancy Compensation Device(BCD) if you want to keep your hands free.
