Deep down in the valley and under the shade of trees in full leaf, even in the early afternoon it was possible to get a 20 second exposure, at least with the help of a polarizer and a 3 stop ND. All I had to do was wait for an obliging cloud to obscure the sun and the effect was there Photograph: Rob Hudson/Flickr Photograph: guardian.co.uk Rough with the smooth . I think I'll have to classify this one as "night photography" as it was taken at 10.21 PM and it's a 91 second exposure, at 200 ISO with no NDs to help lengthen it. In truth though it wasn't really dark by then, probably just at that turning point when the switch from f22 landscape mode to the wide open aperture of night photography would be necessary.

I'm convinced that these clouds all started life as contrails, at least there's no cloud formation that I know that does this. They were mostly invisible to the naked eye, but somehow the Lee Circular polarizer seemed to pick them out. I also used a Lee ND 0.9 and this is a vertorama Photograph: Rob Hudson/Flickr Photograph: guardian.co.uk Dunraven again Photograph: Rob Hudson/Flickr Photograph: guardian.co.uk
