I'm after some help on the rules regarding property releases in the UK. I've been asked by a local gallery to take some photographs a new building in the town for sale in the shop as prints. The building is an art gallery which has a unique architectural style. Shots of a similar building in another town are already sold but if I take the photographs for sale where do I stand?
They'll be arty detail shots and perhaps whole external shots of the building taken from public ground.
