This was the kind of storm you could feel coming long before it was visible. As the dark clouds slowly rolled in, as the wind picked up and the raindrops began to fall, you knew something big was going to happen.
In truth, the scene didn't look quite like this. This is a heavily processed high dynamic range photo (three photos with different exposures combined into one in photoshop or another software package). There are many different ways an HDR image can be processed. I was going for drama here. The colours in the sky are somewhat exaggerated, but they are the colours that were there when I took the photo. There are a few unfortunate artifacts of the HDR process that will be visible if you look closely. So don't look closely.
