PolarPro Fiftyfifty Overview The Polarpro FiftyFifty Dome for HERO9/HERO10 Black is a useful tool for video or photography with GoPro HERO9 or HERO10 Black cameras when shooting at surface level as well as up to 32' below the surface. The dome mounts on your camera and allows access to the foldout mounting point, so you are able to add the optional grip or handle of your choice. The dome is a useful tool for capturing partially-submerged or split shots.The dome surrounds your lens and can be used to create a variety of partially-submerged shots, from the classic half submerged shot with the water line bisecting your frame, to looking downward into the water with a small portion of the frame above water, or with most of the field of view below the surface, looking up above the horizon. Included with the dome is a protective cover for transport and storage as well as a plug that protects the dome from dirt and water when it is not mounted to your camera. Field of View Compensation The dome widens your camera's field of view by 30%, which helps compensate for the increased focal length effect that shooting under water creates. Depth The dome creates a watertight seal to your camera and can be used 32' below the surface, allowing you to shoot above the surface, dive down to follow your subject, or create a compelling point of view shot.
