i was in London recently for the weekend. I was only shooting on film, for a college assignment, but i got some amazing shots. St. Pauls Cathedral is a must! Also, on my last day i did a walk round London, and wish i had done it on my first day! The tour guide showed all these little hidden places i would have never found by myself. They have them all over London, this one wa sonly 6 pound and lasted 2 hours...
Anyways, have a great holiday! its a fab city!
