I am sure that I am not only only photo nerd to keep an archive of cloud photos. They come in handy when you have a blown out sky that needs a little visual interest. It is something I rarely do, composite two different images to create one finished photograph, it tends to seem like cheating to me. Admittedly I will often bracket a scene to capture extra details but it is a photograph of the same subject just with different exposures and doesn't offend my sense of fairness.
Rarely do I share cloud photos, it gets boring, but last night I was out in the country and I couldn't resist sharing this one. Behind me the sky was filled with roiling black clouds broken by the random flash of lightning and a rumble of thunder. I love the colors and the texture in these clouds. Sadly they probably won't end up being part of another image so I felt the need to share it now.
