My studio techniques always fallowed the tenet of keeping it simple. One umbrella and a reflector or just window light and a reflector. My old studio on East 26 Street faced north so I had ideal light. Both of these shots used window light with a reflector. The film was good old Tri-X Pan and the camera was the Nikon F with the Nikkor 105 F 2.5 lens. A combination made in heaven.
