In the picture I see, it's not clear how much closer the man is to the camera than the walrus.
Why that rabbit is 5 feet tall!!1 Not.
Everything there is in the same (bad) focus, no matter how close or how far it is from the camera. It's impossible to estimate, with any confidence, how big the man is just from looking at that picture. Or if the blob on the right is a walrus or not (it looks kinda like an inflatable boat to me, whether or not there was a walrus carcass in the area)...
It looks like all the attempted posts of the video have been taken down due to screaming about copyright.
FWIW.
Cheers,
Scott.
