Rain clouds on Grisedale Pike, viewed from Whinlatter Forest.

This is from last August in Keswick. We'd been climbing steadily higher in Whinlatter Forest and I was getting quite frustrated at the lack of opportunities to see the view, so I was thrilled when the trees opened up at this point and I saw the approaching rain clouds. They only stayed this vivid for a few moments, getting thicker and less defined as they got closer to us.

Camera/lens settings: ISO 200, f/11, 1/200s, 18mm, hand held.
