The second time I visited the Noord-AA lake north of my home town Zoetermeer. I went back to the same spot as last time. There was a fisherman again and the water had a very strong golden reflection of the sun. Of course there is a little post processing done here. But most of the visible effect is because of the gradual 5-stop ND filter I used. It causes fairly strong vignetting but it also makes it possible to use long exposure times.
