When Sara, a friend of mine, asked me to make a video of her doing underwater dancing I started thinking about art. She was the artist and I was being asked to capture her performance on video. I've never done an underwater video before, so I was learning by trial and error - mostly error. We had to film in a public pool with other swimmers around her, which wasn't too bad. I filmed her using three GoPro cameras positioned with tripods and joby suction cups under the water. I used portable Yongnuo lights on the side of the pool shining down into the water. The footage came out a bit grainy, as I expected it would. The compression to YouTube specs made the grain worse.
