Bad weather makes for great photographs, which is contradictory to what most people think. I get a lot of comments from folks on the street who see me with a camera and remark "what a great day for photography" when the sun is shining and not a cloud in the sky. The problem is, nice weather is boring. There isn't drama and contrast to it.
On the other hand, crap weather is great for photographs, even if it's not great for standing around in. For this particular shot, I had some of both. The sky was sunny and nearly cloud-free over my right shoulder, but to my left was a pop up rain storm and heavy clouds. The contrast was remarkable, and made for some great lighting and drama to photograph.
I emphasized the dramatic clouds and contrast of the rain over everything else.... I cropped to 16x9 to give a dramatic air to the whole photograph and converted it to black and white using Nik Silver Efex. Photographed on the coast of Wales with the Leica SL and Leica 24-90mm lens.
