This is a common site in the more touristy spots in London – people taking photos of each other with a famous building/structure in the background. In this case, outside City Hall on the south bank of the river, either the Tower of London or Tower Bridge will be in the background of these people’s photos. But I decided to take photos of the people taking photos. Quite often if I’m spotted with my camera round my neck, tourists will ask me to take their photos with their own cameras. I really ought to start charging!
