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??
Time for another Photo of the Week. This time an Aston Martin taken during the public grid walk before the Britcar 24 hour endurance race at Silverstone. I’ve published images with this ghostly crowd effect before but they are generally created from multiple exposures aligned in Photoshop and layered with stack modes.
It would have been much easier to use that technique on this day as the sun was bright and the car was wrapped in reflective silver vinyl but as I had my tripod and ND filters with me I decided to do it “properly”.
Even with my ND filter in place (I think it was a 6 stop filter) I had to drop my ISO to 50 and stop down to f/20 to get around a 3 second exposure. A nice side effect of being at such a small aperture is the starbursts on the cars highlights.
Ideally I’d have liked a little more blur in the people, but under the bright conditions, with the gear I had, 3.2 seconds was as slow as I could go.
What really lifts the image for me is the fellow photographer lunging in from camera right for a quick shot.
