You are so lucky in the location where you live in SE London, I wish I was down there, I can think of loads of places I would go for a shoot, the only problem I can forsee is having enough battery power to deal with shooting in around 6 - 8 hours of darkness. Each shot requires a long exposure usually around 15 - 30 seconds and sometimes more. I really wish I was there Rose, I would happily give you some help. Start local to you, are there any interesting buildings, churches or bridges that are lit up? Try shooting in shopping centres or capture light trails of traffic like the shots I have posted below.

You should post some of your photos here and us all enjoy them with you.
Can I say a huge thanks to Suzi and yourself for the lovely compliments.
