A few days ago, under a clear, sunny sky, I was marvelled to see Aveiro salt evaporation ponds—one of the areas along the Portuguese coast where sea salt is still produced.
Salt evaporation ponds offer fascinating views for landscape photographers, due to the geometry and regularity of the ponds and the diverse colours they display: blue when fresh saltwater has just entered; red and brown as halophilic bacteria grow during evaporation; and white when the salt is exposed after the water has evaporated.
In this area, the salt is collected and stored in piles at the edge of the salt pans. Now that autumn is approaching, these piles are covered with green tarps to prevent the rain from dissolving the salt. I was captivated by the colours of the landscape and the dialogue between the two salt mounds and the rest of the scenery.
