I shot this on my phone the other day. The sun was so bright I couldn't see what I was doing, so I just held up my phone, pointed it in the general direction of the undercroft, and basically shot blind, only discovering what - if anything - I'd shot when I got home and was able to watch it on the computer.
I'm going to have to go back sometime when it's a bit more overcast (and I can hopefully see what I'm shooting!) and - if I can overcome my shyness - maybe talk to some of the skateboarders and ask if I can shoot them properly. I think I may be turning into a skater girl. ;)
