This image was never originally intended to be this image......I'll elaborate.

The image of the cloud was part of this beautiful long chain of cloud that was drifting along a week or so back. I took a series of about 10 shots with the intention of stitching them to make a panorama. I tried making said panorama with PS CS, but the joins were a little obvious in places, so I abandoned the idea (I'll probably put it together once I get around to getting proper stitching software, as that'll solve the problem).

During shooting these clouds, a brooding thundercloud was frowning upon me about 7 miles west of my position. After shooting, I sat and watched this thunderstorm, as there was frequent flashes, and it made for quite a show.

After a while, the clouds drifted overhead, and whilst the thunder had dissipated, the heavens opened up and proceeded to pour down (luckily I'd packed my waterproof jacket), and I duly shot the rain pounding the waterside where I was.

The rain and the clouds were a large feature of that day, so I put these two images together, as it sums it up nicely.
