Solar Alignment

On 15 September each year, the sun shines down the length of Caen Hill locks in Devizes for a couple of minutes shortly after rising. It also occurs on 28 or 29 March. This image is a high dynamic range capture of four RAW files at different exposures to record detail in the shadows as well as the highlights. The only digital alteration was removal in Photoshop of an unsightly rubbish bin beside the towpath.
