I took this picture at the end of March, 2016. I was testing my new Sigma 10-20 f3,5 lens. This picture contains multiple exposures. One long exposure for the water at f22. Because of the diffraction I had to take another picture at f14 to keep the final image as sharp as possible. And the last exposure is for the sky. After blending the images I used luminosity masks for contrast and exposure balancing.
