Driving down from Helsby to the M56 I noticed the sun was setting behind the chimneys of Stanlow Oil Refinery (or Shell as I call it). Stopping the car I got out the tripod and camera and zoomed in. It took about five or ten minutes wait until the sun just dropped off the horizon and lit up the under side of the dark clouds in the sky. I thought it made a unique foreground for this warm dusk sky, especially with the steam rising into the clouds.
