Some time ago I took quite a lot of shots of traffic crossing the Marine Way Bridge in Southport. I had the camera on a tripod, for obvious reasons. I was trying to capture the perfect set of light trails. What didn’t occur to me at the time was to combine several of the shots in order to get more trails in a single image. Anyway, now I’ve done it: three images with identical exposures merged in Photomatix then processed using Adobe Lightroom, Photoshop and the Topaz Detail plugin for added crispiness!
