Sunbeams through the clouds, drawing on the sea...
In the middle of the picture you can see an islet with a lighthouse on it. It's quite some distance away from the shooting point (Approx. 448mm focal lenght on a 1:1 camera). BTW, it took me 2.5 hours of walking in the cold windy mountains to get this capture.
I used a 70-200 F/4L lense with a 1.4x extender= ~448mm. I shot this from my Manfrotto tripod, though it was almost useless in such strong winds. I also think I held my 77mm cir pol filter in front of the lense here.
Post pro: 5% burn, curves, +20% saturation, tiny bit of noise reduction.
