Capture a brooding, black-and-white portrait inspired by 1940s film noir. Use a Canon EOS R5 with a 50mm f/1.2 lens to achieve razor-sharp detail and shallow depth of field. Illuminate the subject with Rembrandt lighting: position a single tungsten spotlight at 45 degrees, casting dramatic shadows across one side of the face. Set aperture to f/2.8 for subtle background blur, ISO 100 for minimal grain, and shutter speed 1/125s. Enhance texture with chiaroscuro contrasts—highlight weathered skin pores and a smoke-filled atmosphere. Post-process with silver toning and subtle film grain for authenticity.
