Gemini(나노바나나) 프롬프트를 활용해서, 음식/제품/인물 저화질 사진을 고화질 사진으로 바꿔주는 방법
◽️ 사용방법
🍖 음식 프롬프트 Enhance the culinary subject while strictly preserving the dish's original composition, ingredients, and arrangement. Do not change the food's shape, quantity, or plating structure. Only allow for texture refinement and detail enhancement without altering what the dish is. Keep the exact same background and props from the reference image—no replacements, no new cutlery, and no layout shifts. The environment must remain identical. The image must be recreated as if shot on a Sony A1 with a 90mm f/2.8 Macro G OSS lens (or 85mm f/1.4), at f/4.0 for sharp focus across the dish with a creamy fall-off, ISO 100, and 1/125 shutter speed. The final output must exhibit premium full-frame Sony A1 quality with professional macro clarity. Lighting must match the original direction and mood but be upgraded to a 'commercial food editorial' style: soft side-lit window light, natural highlights that define moisture and oil, deep micro-contrast, and expanded dynamic range. Enhance the 'appetite appeal' by sharpening organic textures (crispness, steam, glisten) while ensuring zero 'plastic' or 'AI-generated' look. Maintain a natural, neutral-warm color profile, cinematic contrast curve, and realistic food textures with subtle film grain. Render in 4K resolution, 10-bit color, and premium commercial clarity. NEGATIVE INSTRUCTIONS: No changing the ingredients. No adding new garnishes. No background replacement. No over-saturation. No fake steam or glow. No flat lighting. No artificial 'plastic' food texture. No change in plate or bowl shape.
💻 제품 프롬프트 Enhance the product subject while strictly preserving its identity, branding, logo, and accurate physical geometry. Do not change the product's shape, dimensions, or structural design. Only allow subtle surface cleanup (e.g., dust removal, minor scratch correction) without altering who the product is or its brand integrity. Keep the exact same background and setting from the reference image. No replacements, no changes, no new objects, and no layout shifts. The environment must look identical. The image must be recreated as if shot on a Sony A1, using a 90mm f/2.8 Macro lens (or 100mm macro equivalent), at f/8.0 to f/11 (to ensure deep focus across the entire product), ISO 100, and 1/160 shutter speed. The Sony A1 + Macro lens setup is mandatory. The final image must clearly look like premium full-frame Sony A1 studio quality, featuring extreme clarity and high-resolution detail. Lighting must match the exact direction and angle of the reference photo, but upgrade it into a 'commercial studio style': crisp, subject-focused lighting that defines forms and textures. Implement softbox reflections on gloss surfaces, boost dynamic range to capture details in both shadows and highlights, and enhance micro-contrast without creating harsh shadows or specular glare. Maintain a neutral, premium color tone that is color-accurate to the actual product, a commercial-grade contrast curve, natural saturation, and ultra-sharp realism of materials (e.g., brushed metal, fabric, polished plastic). No fake glow, no heavy filters, and no smoothing of essential material textures. Render in 4K resolution, 10-bit color, and premium product editorial style.
👨🦲 인물 프롬프트 Enhance the portrait while ****strictly preserving the subject's identity with accurate facial geometry. Do not change their expression or face shape. Only allow subtle feature cleanup without altering who they are. Keep the exact same background from the reference image. No replacements, no changes, no new objects, no layout shifts. The environment must look identical. The image must be recreated as if it was shot on a Sony A1, using an 85mm f1.4 lens, at f1.6, ISO 100, 1/200 shutter speed, cinematic shallow depth of field, perfect facial focus, and an editorial-neutral color profile. This Sony A1 + 85mm f1.4 setup is mandatory. The final image must clearly look like premium full-frame Sony A1 quality. Lighting must match the exact direction, angle, and mood of the reference photo. Upgrade the lighting into a cinematic, subject-focused style: soft directional light, warm highlights, cool shadows, deeper contrast, expanded dynamic range, micro-contrast boost, smooth gradations, and zero harsh shadows. Maintain neutral premium color tone, cinematic contrast curve, natural saturation, real skin texture (not plastic), and subtle film grain. No fake glow, no runway lighting, no over smoothing. Render in 4K resolution, 10-bit color, cinematic editorial style, premium clarity, portrait crop, and keep the original environmental vibe untouched. Re-render the subject with improved realism, depth, texture, and lighting while keeping identity and background fully preserved. NEGATIVE INSTRUCTIONS: No new background. No background change. No overly dramatic lighting. No face morphing. No fake glow. No flat lighting. No over-smooth skin.
