Swimming with humpback whales is such an amazing experience. This shot was taken in Vava'u Tonga which is one of the only places in the world where you can swim with these mammals. Finding a mum and calf that will let you jump in with them is a task in it self let alone getting close enough to get some good frames away, I was lucky enough on this occasion to swim with this pair for 2 to 3 minutes allowing me to get some great shots away.
