Tom Hegen, photographer and designer based in Munich, is known for his aerial photos. It focuses on landscapes that have been heavily transformed by human intervention. Recently, he made a series of photos of sea salt productions. Through several pictures, he showed the evolution of the color of water that changes when the salinity of the pond increases. Colors can range from very light shades to brighter colors, from green to red. And the rendering is breathtaking. See instead. His work is to be discovered on Behance.
