- Test settings
- Reference photo: an AI-generated picture of a fictional man (not a real person), made in Gemini for this test. Uploaded with the default copy text unchanged in a new Gemini chat. First result used; only converted to WebP.
- Variability
- Faces, poses and small details vary between runs; always compare the result with your own photo. Gemini adds a small sparkle watermark in the corner.
Use the uploaded photo as the reference for the person. Preserve their recognisable face, natural skin tone, hairline and build as closely as the model permits; check the result against the reference. Scene: a dim detective's office with a wooden desk at night, cigarette-free haze in the air, a single desk lamp and a window with venetian blinds. Moment or Pose: three-quarter turn toward the window, chin slightly lowered, eyes looking just past the camera, one hand resting on the brim of a hat or the lapel. Clothing: a charcoal double-breasted suit with a fedora, period-correct 1940s tailoring. Light: one hard key light through the blinds casting striped shadows across the face and wall; deep blacks, no fill. Camera: 50mm lens, eye level, shallow depth of field, slight film grain. Style: classic black-and-white film noir still, high contrast, silver-gelatin tones. Format: vertical 4:5. Avoid: colour tints, changed face, plastic skin, extra fingers, text or watermarks, modern gadgets.
