I am a professional wave photographer from Hawaii. I travel and shoot waves from all over the world. I usually have a GoPro 3 attached to the top of my waterhousing which I will turn on when there is a nice wave going towards me.
The heart beat sounds you hear is my shooting still images with my camera. This is just one wave, I am compiling a video with many of my favorite shots which I will upload in the next week or so.
