Popcorn Dolphins

This is one of those shots where I have to assure people that the animals are 100% wild. Several years ago we came across a group of about 30 Pacific white-sided dolphins off the south end of Quadra Island, B.C. This was a beautiful afternoon in late October and the colors of the changing foliage were stunning. We watched the dolphins for over an hour engage in these "popcorning" displays. I'm not quite sure if this was purely social or perhaps some mating behavior going on here (probably both!), but it was a really special encounter. I cropped this image about 50% and ran it through a Nik Software detail extractor because I wanted to pick up more detail in the foliage. Maybe it works. Maybe it doesn't. I tried to keep it subtle.
