Photos from a night shoot in Central London

Experimenting with long exposures, in particular at night, has long since been an interest of mine.  When initially shooting on a 35mm SLR I love the idea and element of surprise; were the images going to be correctly exposed or would I have an entire blank roll of film?

Since moving on to a DSLR some of that experimentation has been lost and I hope in the near future to move back to 35mm to re-capture the excitement once again.
