Thanjks for your comments Matt. I tend to be a bit up-front about public/candid shots - if you just get on with it nobody seems to bother but if you look furtive or worried about being seen then you will. Security guards can only ask you to stop shooting, which I will, but it only happened once (touch wood) and that was in a store.

Where I will definitely ask permission is in a museum/stately home etc.
