So taking pictures underwater is difficult. I have a tiny, cheap camera that is hard to maintain in an er like not jerking around state. If you are on the surface snorkeling then the stuff is happening too far away. If you are scuba-ing then you tend to go deeper and thus the lack of light washes out all the colors and the photos are gloomy. Today I try an experiment by going out in front of the house but with a tank. The idea is to sink down to the bottom and stay there for a long time as motionless as possible, reassuring the fish that everything is hunky dory and hopefully establishing a reasonably solid platform so as to take photos that are in focus. I am in about 5 feet of water.
It is a lovely day and the water is warming.
Neil, Great post! Could you do an experiment for me? Next time you do this, point the camera straight up and take a picture. Record the depth and let me know the model number of you camera. This will help me find dark matter. Explanation to follow.
Dark matter. No problem. Do I get my name on the publication?
