Tom Hegen is back with mesmerising aerial shots of Western Australia's sea salt production

Now the German photographer is back with Salt Series Part II and this time he has flown above Western Australia to once again capture the impact of human intervention in natural environments. These new photographs feature an incredible pastel-coloured palette of one of the most beautiful salt production sites in the world.

"Sea salt is a product that is heavily included in our everyday life but we hardly know where it comes from and how it's been produced," says Hegen. "Seawater is fed into evaporation ponds. Energy from the sun and wind concentrates the water to help encourage salt growth. The colour of the water comes from micro bacteria, which changes their hues when the salt concentration rises. Once ponds are completely dried out, a layer of salt of around 25cm in the pond is ready to harvest. After harvesting, the salt gets washed and ready for transportation."
