Sometimes they can be ominous, especially night surfing pictures. I have often wondered, on a dark night with no moon, can a shark see the surfer floating on the surface, paddling for the next wave and think they are a seal?
I've corresponded with a few people who have enjoyed night surfing. They realize the dangers, but they claim it's exhilarating none the less.
I have plans to do a few more night surfing pictures in the future, if I can get "Jaws" out of my thoughts.
