The river is commonly called the “River of Five Colors” or the “Liquid Rainbow,” and is famous for its striking colors. Besides the crystal clear water, the bed of the river is variously colored yellow, green, blue, black, and especially red, this is all caused by the unique vegetation growing on the riverbed: the Macarenia Clavigera plant.
Because of the heavy sun we had that day, I used a B+W Polarisation filter to avoid reflections on the water surface, in that way the colors become more pronounced. It was also the first time for me shooting free hand in bracketing mode, normally you use a tripod for this kind of photography. For one final photo, I took seven, each with a different aperture and afterwards I merged them using Adobe Photoshop as a 32-bit image, which resulted into a High Dynamic Range photo or HDR. Hope You like them!
