• Framing & Shot Type: Low-angle hero perspective (Slight low angle looking up to create visual presence)


• Optics & Focal Intent: 105mm macro detail lens at f/2.8 balanced subject sharpness with soft background bokeh


• Lighting Atmosphere: Moody chiaroscuro single-source key light with deep velvety shadows


• Color Grading: Subtle film stock aesthetic with lifted blacks and soft highlight rolloff


• Model Constraints: Preserves natural skin texture; avoids oversaturated smoothing.
