It wasn't before, it's just impossible to get a shot of the Dave because he doesn't show up on most cameras. You have to be a fucking skilled photographer to actually capture his essence in any way at all... nice job Ian, I'm impressed.
DUDE the dave is very rarely photographed in his natural habitat, and they've never had one in captivity. this is a rarity, to be sure. excellent. C.R.E.A.M.
