This is a shot of a storm approaching Boston during a very hot summer evening, it was taken with a 10 stop ND filter to get the movement in the higher clouds, the lower clouds were a lot slower and this is clearly visible. The wide angle helps with the look of the clouds streaks, there is nothing fake about the sky and post processing is minimal in this one. As it was extremely hot, over 100 F, my sensor overheated causing a lot of hot pixels, that were easily fixed in post.
