Setting

When the teenagers are walking along at night they need to look like they have just been to town but are walking around the back alleys rather than the center of town. This will be filmed in daylight so the film looks better but then a night filter shall be added later. - Cambridge Leisure Park

When the killer is developing the photo and planning. This can be filmed in lesson time as it is dark already in the room with just the dim white light and bright red light as wanted. - Long Road traditional photography room (development dark room)
