Clouds over Edinburgh
A detail of the cool clouds as seen in the previous photograph.
I'm glad I made the effort to get my tripod for this one (I'd just cycled all the way across Edinburgh in busy traffic with it on my back!) as I don't think this would have turned out nearly as well if I hadn't.
That's a rainstorm that's coming in from the left. It's a bit of a shame there's no Edinburgh landmarks in this shot (the city centre is off to the right) but I guess you you can't have everything!
