Seeing the two adults ascend at the same time - with their eyes on me - was an incredible experience. They were giants - 10 times my size and many many times my weight.
But the penultimate experience happened on Wednesday when we swam with a group of 4 to 6 large adult whales. We saw them in the distance breaching many times. As we approached they got shy but we followed - and swam - followed and swam... Eventually they realized we were not a threat and began to come closer to us even circling around us. After two hours - they were swimming right alongside us - even singing.
My GoPro battery ran out exasperatingly at this moment. I wasted a lot of battery life filming the action on the surface. And I chose maddeningly not to bring a 2nd battery which I was holding in my hand before the event.
I had dropped my Canon on the concrete floor a few days before - and broke my 16-35mm lens. So I couldn't use it for this amazing shoot. Darn it.
