The appearances of false-color infrared photos including water are often quite hard to predict. In this case, the already clear waters at Crystal Cove were made not only more clear, but turned to a deep shade of blue. A very large reason for this is that liquid water has an optical density peak around 760nm, a very important wavelength area in near-infrared photography. This same reason for water appearing blue to our eyes is multiplied when observing primarily near-infrared light. Conveniently, this leads to visually exciting imagery and magically surreal scenes, almost totally different than what we would see on any given day.
