Free Light
As a physicist, I would regard all photons as common property, if a photographer doesn't absorb them with his camera detector then they get absorbed somewhere else, maybe into the eye of a passing pedestrian who would not take kindly to having his eyeballs seized.
Apart from the photons emitted from the thermal radiation of the Port of Tyne wall the photons are mostly scattered sunlight which is not under anyone's jurisdiction or ownership (yet).
