Location Shots - Alleyway Scene

The location I have chosen is a small path which goes up a hill. It is surrounded by brick walls, or gothic railings. There is also a church and graveyard that surrounds it. The street lights are old fashioned too, they could be victorian. There is however a problem with the lighting, it is a large area to cover, and i think the camera will be following someone, i will have to light the scene very carefully. The street lights are very orange, and i want the scene to b more grey/blue, so i think the only way i can get round this will be in post-production.
