Shadows from clouds across the Littleborough valley

I took this from the track around the reservoirs at Blackstone Edge in March this year. You can see for miles around from up there and I like watching the ever-changing patterns made on the opposite hills by the clouds as they move across the sky.

A sharper photo would be made by stitching several portrait photos together, but having not taken my tripod, this one is just a crop from a 2:3 landscape shot.

Camera/lens settings: ISO 100, f/11, 1/160s, 18mm, hand held.
