The thing I noticed while watching Blade Runner, is most of the scenes capture a singular person. The space is causing different lighting, and causing your eye to focus on the character in the frame. The helicopter scenes would have the camera facing down, onto the towering buildings and the streets below, giving you the characters perspective.
The timeless elements of Noir captured are lighting (the dim, not very revealing kind), sex, and murder. Oh, and generally there’s a city scene or two found. It doesn’t necessarily need a smoking, evil, mastermind, fedoras, or detectives. Those are still awesome elements though, and looking hard enough you can make connections to those elements in today’s films
