This afternoon I’d been photographing Tewet Tarn near Keswick. It’s more of an early morning location, hopefully with interesting colour on Blencathra in the background (note to self – no more lazy lie-ins), but I was there from around midday hoping to get a panorama with Skiddaw in the frame too. At this time of year midday light doesn’t always rule out photography and the Lake District’s fast changing clouds will often shape the light so that even when your back is to the sun it’s still possible you’ll be there when there is a sudden dramatic contrast between the hills and the tarn. But today the cloud breaks were brief and seemed to be getting briefer, and it wasn’t really worth staying long as I did – I wasn’t going to get better light. After all, I was thinking, what do you really deserve when you’re almost following others’ tripod holes rather than finding your own views?

And that was when I looked behind me. It’s usually a good idea.
