4" Portable Diving Dome Port Underwater Photography Cover for Xiaomi Yi Action Camera

Description
If you just use the camera, it's pretty tough to shoot half underwater/ half and half photos, because the
water line, filed of view and underwater magnification stop you doing that, so to even things out, you need
this dome port!
 
The dome pushes the water line away from the lens, the field of view is increased,above and below the
water line, it gives you very cool pictures.
 
The water magnifies things. This distorts the look of photos, making the above water objects look normal
while the underwater objects look larger. With this dome port, it normalizes the field of the view, it match up above and below the water line, which gives you a real world.
