Image of Tiberina island on the Tevere river after one week from the raise of the water level. In the central area you can still see some traces of sewage sludge. I took this HDR placing my camera on a small tripod on the railing that overlooks the river. HDR made from 3 exposures (+2, 0, -2). I used the shot underexposed exposure to remove some overexposed areas of the image, then using filter gaussian blur I smooth the water to increase the effect.
