^ It is a bit of a grey area. You are legally permitted to shoot film/photos of private property (buildings) from a public space (sidewalk)... as long as you're not invading someone's privacy. Using a long-lens on visible people situated on private property is considered an invasion of privacy, so in theory, construction workers could complain.
Film or photos of people in public places (street, sidewalk, park) where there is no reasonable expectation of privacy, is fine... unless you use someone's image to sell a product, then it's considered an infringement on their right of publicity.
Great pics though!
