The river is commonly called the "River of Five Colors" or the "Liquid Rainbow" and is famous for its striking colours. Besides the crystal clear water, the bed of the river is variously coloured 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, I used a B+W Polarisation filter to avoid reflections on the water surface, so the colours 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 merged seven images! I took each photo with a different aperture, and afterwards, I merged them using Adobe Photoshop as a 32-bit image, which resulted in a High Dynamic Range photo or HDR. I hope you like them!
