I took these as a demonstration of a specific photography technique that appears to work extremely well in reef tanks. It was done by holding a narrow, bright beamed light source, such as a small car flashlight above the tank, less than a centimeter above the water.
The the water diffused and negated the outlying weak light, while lightly spreading the main beam. This allowed for a pitch black background with superior focus on the subject.
This worked better in a tank that is shorter.
