Barge moving along the Rochdale canal

I took this on a late afternoon at the end of October this year, just outside Sowerby Bridge. I had just set my tripod up to take photos of the autumn foliage when I saw this barge appearing from the tunnel in the distance. I liked the idea of getting a long exposure motion shot (making one of the slowest-moving forms of transport look super-fast!) so had to quickly attach ND filters and guess my camera settings, knowing I'd only get one chance at it. Happily, it worked!

Camera/lens settings: ISO 100, f/11, 30s, 20mm, ND filters, tripod.
