Growing up in southern California, we would occasionally go out on whale watching trips to see grey whales. While I like to dive with many big animals like great whites, whale sharks turtles, and other sharks, when a trip came up to swim with the humpback whales in Tahiti I jumped at the chance!
The season for them in Moorea runs from about August through mid-November. Earlier in the season is better weather, later in the season is better for finding calves with their mom but weather may be less predictable.

There are restrictions to swimming with the whales: snorkeling with fins, but no scuba; no flash photography; either 100 yards for a solitary whale, or 300 if a calf; and no touching. It may take a long time to find a whale, but when a whale is spotted, be prepared to swim fast and hard to get to the whale, because the time you may get to spend with them is unpredictable.

Normally I shoot in manual mode, but since the interactions with a whale can vary quickly, I did not want to waste time trying to set the right exposure. I set the camera in aperture priority mode, and high speed shutter repeat. All pictures were shot with a Canon 5D Mk IV inside an Ikelite Underwater Housing, Canon 17-40MM L lens inside the Ikelite 8inch Dome Port. While I also have the 8-15MM fisheye, I wanted to start with the bigger lens to see what range was required. Of course, that also depends on how close you choose to get to the whale. I started off a little further away, remembering that this is a big animal that can move fast, so clarity suffered a little. Of course, remember there are other divers who also want to see the whale. Several times I had to swim away because the whale turned quickly.
