Rio Tinto in Huelva, Spain, is a highly acidic river (ph 2) that has a deep red hue due to the iron concentration in the water.

The highly saturated colors make fantastic and unreal landscapes, perfect for our preferred hobby.

The source of the Rio Tinto is an open cast mine localized in Nerva. An amazing place with lots of abandoned mining facilities and a source of photographic possibilities.
