It handles subtle things like skin texture, facial geometry, and background consistency. That makes it ideal if you want to preserve identity.Start by uploading your portrait in JPG or PNG format. Tiny, blurry images might work, but the AI often produces cleaner results with slightly better quality originals.Step 2: Write a clear promptA good prompt is short, precise, and clear. Here’s a version you could use:Prompt 1:Enhance this portrait while keeping the person’s identity, face shape, and expression exactly as in the original. Only subtle cleanup is allowed. Keep the background unchanged with no new objects, no swaps, no layout shifts.Recreate the image as if shot with a Sony A1 camera using an 85mm f1.4 lens at f1.6, ISO 100, 1/200 shutter speed. Shallow depth of field, sharp facial focus, and natural editorial colours are important. Lighting should match the reference, with soft highlights, cooler shadows, gentle contrast, and smooth gradations.Keep skin textures realistic, slight film grain, and natural saturation. Render in 4K, 10-bit colour, portrait crop, cinematic style. Avoid fake glow, harsh lighting, or over-smoothed skin. Prompt 2:Upgrade the portrait to premium clarity while strictly preserving the subject’s identity and facial geometry. Expression and face shape should not change. Minor feature clean-up is fine, but nothing drastic.Keep the background identical with no additions, replacements, or rearrangements. The scene must look exactly as in the reference.Simulate a high-end Sony A1 with an 85mm f1.4 lens, shallow depth of field, and perfect facial focus. Lighting should follow the original direction and mood, with soft shadows, warm highlights, subtle micro-contrast, and smooth tonal transitions.Maintain natural skin texture, neutral colour tones, and subtle grain. Render in 4K, 10-bit, portrait crop, cinematic editorial style. Avoid fake glow, flat light, or face morphing. Prompt 3:Improve this portrait while keeping the subject completely recognisable. Do not change facial proportions, expression, or identity. Only allow very subtle touch-ups to refine features.Background must remain exactly the same with no new objects or layout changes. The environment should feel identical to the original.Render as if taken with a Sony A1 camera and 85mm f1.4 lens. Aim for cinematic shallow focus, perfect facial detail, and realistic editorial colours. Lighting should match the original photo with soft directional light, warm highlights, and cooler shadows for depth.Preserve real skin texture, natural saturation, subtle film grain, and smooth contrast. Output in 4K, 10-bit colour, portrait crop. Avoid background alterations, over-smoothing, fake glow, or harsh lighting. Step 3: Click ‘okay’ Once the prompt is ready, run it in Google Gemini. Usually, it takes only a few seconds. The AI reportedly sharpens facial features, balances lighting, and keeps the environment intact. Results often look immediate. But sometimes minor tweaks are needed, depending on the original image.
