I had to go to London on Friday as I am taking photographs for a work competition so while I was there I took the opportunity to take this image for myself. I took this from the end of platform 4 at London Bridge Train Station. On arrival I went to Network Rail office and got their permission to take some images using my tripod. They issued me with a permit and I was good to go. The stunned silence of the security staff was brilliant when they approached me telling me " You need a permit to take pictures" When I produced one they were just stunned it was priceless !
This was taken on a tripod with a Lee Big Stopper for just over 60 sec exposure.
