This image was taken a few years ago as a Get Off My Ass mission – I’d not been out with my camera for a while and decided that tonight would be the night. I don’t recall what gave me the idea but I decided on shooting some light trails and fired up Google Maps to find a suitable location.
This bridge is just north of the M4/M5 interchange outside Bristol. I like this location for the curve of the road leading towards the RAC tower and the light pollution from the city giving the sky some interest. I took a batch of images, a couple to get the right exposure for the sky and the rest at 15 seconds to capture the light trails. You get surprisingly few cars in 15 seconds leaving sparse trails so 4 frames were layered in Photoshop (using the Lighten blend mode) to give better density.
Overall I am pleased with the image but looking back at it now I can’t help but see one thing: The blue mile marker sign on the left hand side! How did I not see that glowing reflective blue square when I first edited it??
