The ironic thing is one of the secondary characters in this show is a photographer. Everything up until the only scene where you actually see him with a digital camera (in which a main character used it to shoot a subject very far away when the camera clearly had a short focal length lens on it) indicated that he shot film. Everything was black and white, he was 'going to the lab', etc. Also, his studio apartment obviously housed a photographer. Look at all of those light stands, a professional grade printer, and file cabinets full of prints!
