This is Castlepoint Lighthouse, on a day when the weather seems to be blowing a different season every hour and we were just moving through "spring".  Processing this from a single raw was really hard (and I'm still not totally happy with this) but I think the image has potential, and it did manage to scrape through QI assessment on Wikimedia Commons.  I've tried HDR on it but it turns the clouds into armageddon-like overdone hyper-reality, when the reality is quite interesting enough.

I'd be interested to hear what advice people can offer.
