Photographer's Note

The Blue Lagoon is a geothermal hotpool swimming complex just outside of Reykjavik.

It's not a natural hotpool, it has formed because of the nearby geothermal power station. Cold sea water is pumped down, deep into the earth where the temperatures are so high that it comes back up as superheated steam. This steam is used to drive the power station turbines and then it is condensed back into liquid water and drained out into this pool at a constant temperature of around 35-40 degrees C.

The blue/white colours you see are totally genuine. They are caused by the algae and silicates in the water.
