Why do people keep quoting copyright in these matters ??
Copyright, or more correctly Intellectual Property Rights, don't kick in until you actually do something with the images, so put that aside. It is absolutely correct to say that you own the images and anybody would be daft to disagree. If somebody took them and used them they would have breached your rights as owner. If you are a private individual it is assumed that you are taking the images for personal use (remember when life was simple before flikr and You Tube)
Taking the pictures, you need permission of the landowner.
If you broadcast/publish the images you have to have consent of any identifiable individuals under Data Protection to use the images for that purpose. This is why we can be CCTVd, as the images are not transmitted or broadcast, and can only be retained for 3 months unless a crime has been committed.
(members of the Press, which includes BBC news, have a different set of protocols, I am assuming you are not a journalist or you wouldnt be asking this question on an mtb website. The Police also have wider powers)
It's a complex business, and the law takes a while to catch up with technology.
I also deal with this kind of thing for my actual paid job.
