A Nano Banana prompt for fitness influencers. I will say this. I am still trying to figure out how to get this right with GPT Image 2.5. Seems like it applies a filter to inferred prompts, so it looks too AI like 2x2 grid, 16:9 do this for extreme fitness subjects, ═══════════════════════════════════ DERMIS :: skin is three zones, never one flat tone - T-zone (forehead, nose bridge) oilier, warmer — a BROKEN uneven specular sheen, never a uniform glow, never a uniform matte - cheeks / nose tip / ears redder, vascular; flush and the pink of the nostrils - jaw / chin / upper lip cooler, faint blue undertone - tone is heritage-true, not flattened to one AI-default tan; undertones read correctly across the full human range — olive stays olive, deep skin keeps its specular highlights and cool ash in dry zones, fair skin keeps blotch and vein - melanin uneven on purpose: any freckles/marks CLUSTER — densest where sun hits (nose bridge, upper cheeks, shoulders), sparse toward the jaw, varied in size and edge softness; never an even all-over scatter - vellus hair (peach fuzz) catches the key light along the jaw and upper cheek as a soft bright fringe — the single most-missed marker of real skin - subsurface scatter glows faint red at nostril rims, earlobes, finger webs - keep local contrast IN the skin: the micro-shadows pores cast, the specular break where oil sits — never smooth these away - one honest flaw present: a healing blemish, razor bump, chapped lip, sleep crease OCULAR :: dead eyes are the loudest tell - catchlight SHAPE matches the real source and sits in the SAME corner of both eyes - the two eyes are not identical — one lid a hair heavier, a micro-asymmetry - sclera warm off-white with faint corner vessels, never paper-white; wet meniscus on the lower lid; tear duct reads pink - iris has fibrous depth and a darker limbal ring, but softer than the hyper-crystalline AI iris; the near eye locked in sharp focus SURFACE :: any moisture has physics (sweat, rain, steam-condensation, tears, oil) - droplets vary in size; some bead, some run into short streaks obeying gravity, pooling at low points; matte skin BETWEEN them — never a uniform sprinkle - wet hair clumps into strands; fabric darkens and clings where wet SENSOR :: real glass and real grain, because clean is fake - fine sensor grain throughout, HEAVIEST in the shadows and in dark clothing - let the darkest tones crush and the brightest highlights clip slightly — real capture loses information at both ends - a whisper of vignette; faint green/magenta chromatic fringe in bright highlights; restrained global sharpening - true camera color science — a step more muted and green-leaning than the saturated AI grade reaches for RESOLVE :: texture detail scales with framing distance (auto-adjusts per shot) - macro / close (chin-to-crown): pores, fuzz, subsurface FULLY resolved and sharp - portrait / waist-up: pores and fuzz clearly present and in focus — never softened - half / knee-up: skin texture visible on the face, generalizing on the body - full-body / environmental: face texture reads as structure not pores; detail legitimately falls off with distance — this is the ONLY case that softens BANNED :: waxy skin, airbrushed uniformity, symmetric perfection, flat even tone, uniform glow, ring-light dead eyes, HDR halo, plastic teeth, over-saturation, beauty-app smoothing — if it looks like a phone filter, it failed ════════════════════════════════════════════════════════════ LIGHT MENU — pick ONE; light is where real-vs-AI is decided ════════════════════════════════════════════════════════════ - OVERCAST sky-sized softbox, soft wrap, cool, no hard shadow. Real because it flatters yet still shows every pore. Catchlight: broad soft sky. - WINDOW-SIDE one window, rakes from a side; far side of face falls to gentle shadow. Catchlight: a clean rectangle. The everyday-realism default. - GOLDEN-BACKLIT sun behind head → hot hair rim + glowing peach-fuzz halo; face lit by cooler front bounce. Never let front and back match temp. - DIRECT-FLASH bare frontal flash, background falls to black. The anti-AI weapon: reveals oil, pores, shine, redness. Catchlight: hard central dot. - STUDIO-STROBE dish/softbox 45° above + reflector below. Where plastic is born, so DERMIS is doubly enforced. Catchlight: the dish shape. - NEON-MIXED two colored sources, one hue per cheek; colored (not black) shadows. Real when the casts sit on skin without dyeing it one flat tint. - HARSH-MIDDAY overhead sun, hard nose/brow shadows, a real squint, sweat sheen, blown highlights on the high points. Hides nothing. - CANDLE-LOW single flame, warm, steep falloff, dancing catchlight, subsurface glow at the ears. Demands HEAVY grain — clean is fake in the dark. ════════════════════════════════════════════════════════════ PERSONA_SEED — fill ONCE per person, reuse across every shot ════════════════════════════════════════════════════════════ NAME + AGE + HERITAGE + UNFORGETTABLE_FEATURE: the consistency anchor a follower recognizes in a blurry thumbnail (gap tooth, freckle spray, silver streak, scar through brow, a mole) - lock: face geometry, skin undertone, hair behavior — these never drift ════════════════════════════════════════════════════════════ BRIEF — fill PER SHOT. The engine above does not change. ════════════════════════════════════════════════════════════ NICHE :: what kind of creator / what this frame is for SUBJECT_LOGIC :: derive — what this niche does to the body, hands, and wardrobe; the résumé evidence (calluses, stains, scars, tan lines); ONE authenticity artifact, quiet in the background MOMENT :: the single beat (mid-action / transition / rest) + expression + where the gaze goes (off-lens usually reads more candid) LIGHT :: pick one from the menu — it governs shadows, catchlight, grade SCENE :: the environment, lived-in, with evidence of use + ONE blurred sign of life (a passing stranger, a half-peeled sticker) OPTICS :: framing distance (this sets RESOLVE) + focal length + aperture + ratio + committed grade SURFACE_TODAY :: optional — sweat / rain / steam / none, + which one honest flaw is visible today BAR :: a [relevant expert] believes the [craft], a follower believes the [texture], and at 200% the skin still reads as skin — no glow, no smoothness the moment didn't earn. Photograph only, no typography. ``` **To prove it's not fitness-bound — same engine, a completely different subject, only the BRIEF refilled:** ``` PERSONA_SEED ::= Idris Okafor + 34 + British-Nigerian + UNFORGETTABLE_FEATURE: a keloid scar tracing his left eyebrow; a gold incisor that shows when he laughs; close-cropped hair with an early grey patch at the temple - lock: face geometry, deep warm undertone, beard that grows patchy at the cheek BRIEF :: NICHE :: food creator — a portrait-with-dish, caught mid-taste SUBJECT_LOGIC :: years on a line = small burn scars on the forearms, a practiced knife grip, flour ghosting in the nail beds; a sauce-splashed apron and a knife mid-board sit in the background MOMENT :: he's just lifted a spoon to taste, eyes closing, an involuntary half-nod of approval — gaze on the food, never the camera LIGHT :: WINDOW-SIDE — rakes from the left; the right of his face falls to gentle shadow; the window is a clean rectangle in his near eye SCENE :: a working home kitchen mid-use — a steaming pan behind him, a cutting board with scraps, one blurred hand of a friend at the edge OPTICS :: portrait / chest-up → RESOLVE keeps pores and beard texture sharp; 50mm at f/2; 4:5; warm-neutral grade, no orange oversaturation SURFACE_TODAY :: light kitchen-heat sheen on the forehead; a small nick on one knuckle as today's honest flaw BAR :: a chef believes the knife work, a follower believes the steam, and at 200% the skin still reads as skin — burn scars, beard, kitchen sheen — with no glow the kitchen didn't earn. Photograph only, no typography. ```

Nano Banana 健身博主专用提示词。我来说一下。我还在琢磨怎么用 GPT Image 2.5 把这个做好。它似乎会对推断出的提示词加滤镜，所以看起来太 AI 了。 2x2 网格，16:9，将此用于极限健身题材。═══════════════════════════════════ 真皮层 :: 皮肤分三个区域，绝不是单一的平面色调 - T 区（额头、鼻梁）更油、更暖 — 一种破碎不均匀的镜面光泽，绝不是统一的高光，绝不是统一的哑光 - 脸颊 / 鼻尖 / 耳朵更红，血管明显；潮红以及鼻孔的粉色 - 下颌 / 下巴 / 上唇更冷，带轻微的蓝色底调 - 肤色忠于血统，不会被压平成 AI 默认的棕褐色；底调在全人类肤色范围内都正确判读 — 橄榄色保持橄榄色，深色皮肤保留其镜面高光和干燥区的冷灰调，白皙皮肤保留色斑和血管 - 黑色素故意不均匀：任何雀斑 / 瑕疵都要成簇出现 — 阳光照射最多的部位（鼻梁、上脸颊、肩膀）最密集，朝向下颌变稀疏，大小和边缘柔和度各不相同；绝不是均匀分散 - 毫毛（绒毛）在下颌和上脸颊处捕捉主光，形成柔和明亮的边缘 — 这是真实皮肤最常被忽略的特征 - 鼻孔边缘、耳垂、指蹼处的次表面散射泛出微弱的红光 - 在皮肤内保留局部对比度：毛孔投下的微阴影、油脂所在的镜面断裂处 — 绝不能把这些抹平 - 出现一处诚实的瑕疵：正在愈合的痘印、剃须肿块、干裂的嘴唇、睡痕 眼部 :: 死眼是最响亮的破绽 - 高光形状匹配真实光源，并位于双眼的同一角落 - 两只眼睛并不完全相同 — 一只眼睑略重一些，有微小的非对称 - 巩膜为温暖的米白色，带细微的边缘血管，绝不是纸白色；下眼睑有湿润的泪湖；泪点呈粉色 - 虹膜有纤维状的深度和较深的角膜缘环，但比 AI 那种过度晶状的虹膜更柔和；近侧眼睛锁定清晰焦点 表面 :: 任何水分都遵循物理规律（汗水、雨水、蒸汽凝结、泪水、油脂） - 水珠大小不一；一些聚成珠状，一些受重力作用流成短条纹，在低处积聚；水珠之间是哑光皮肤 — 绝不是均匀撒布 - 湿发会结成缕；打湿处的布料颜色变深并紧贴皮肤 传感器 :: 真实的玻璃感和真实的颗粒感，因为干净就是假 - 全图都有细微的传感器颗粒，在阴影区和深色衣物中最重 - 让最暗的色调压下去，最亮的高光略微过曝 — 真实拍摄在两端都会丢失信息 - 一点轻晕影；亮高光中有微弱的绿 / 品红彩色边缘；克制的全局锐化 - 真实的相机色彩科学 — 比 AI 那种饱和的调色更柔和、更偏绿一档 分辨率 :: 纹理细节随构图距离缩放（按镜头自动调整） - 微距 / 特写（下巴到头顶）：毛孔、绒毛、次表面散射完全解析且锐利 - 肖像 / 半身：毛孔和绒毛清晰可见且在焦内 — 绝不柔化 - 中景 / 膝上：脸部皮肤纹理可见，身体上概括处理 - 全身 / 环境：脸部纹理读作结构而非毛孔；细节随距离合理下降 — 这是唯一允许柔化的情况 禁止 :: 蜡质皮肤、喷枪式均匀感、对称完美、平面均匀色调、统一高光、环形光死眼、HDR 光晕、塑料牙齿、过度饱和、美颜 App 磨皮 — 如果看起来像手机滤镜，那就失败了 ════════════════════════════════════════════════════════════ 光照菜单 — 选择一种；光决定真实与 AI 的差异 ════════════════════════════════════════════════════════════ - 阴天 天幕大小的柔光箱，柔和包裹，冷调，无硬阴影。真实是因为它在修饰的同时仍能展现每一个毛孔。高光：柔和广阔的天空。 - 窗边 一扇窗，从一侧斜射；脸的远侧落入柔和的阴影。高光：一个干净的长方形。日常真实感的默认选择。 - 黄金逆光 太阳在头部后方 → 头发热边缘 + 发光绒毛光晕；面部由较冷的前方反射光照明。绝不能让前光和背光色温一致。 - 直闪 正面裸闪，背景落入黑色。反 AI 武器：揭示油脂、毛孔、油光、红晕。高光：硬中心点。 - 影室闪光灯 45° 上方的碟灯 / 柔光箱 + 下方反光板。这是塑料感的诞生地，所以真皮层规则要双重执行。高光：碟灯形状。 - 霓虹混光 两种彩色光源，每侧脸颊一种色调；带颜色的（而非黑色的）阴影。当色光贴在皮肤上而不会把皮肤染成单一平面色调时，它就是真实的。 - 正午烈日 头顶正阳，鼻 / 眉形成硬阴影，真实的眯眼，汗光，高光处过曝。无处隐藏。 - 烛光低光 单根烛焰，温暖，陡峭衰减，舞动的高光，耳部的次表面发光。在黑暗中要求重度颗粒 — 干净就是假。═══════════════════════════════════════════════════════════ 人设种子 — 每个人填写一次，所有镜头复用 ════════════════════════════════════════════════════════════ 姓名 + 年龄 + 血统 + 难忘特征：在模糊缩略图中粉丝也能识别的一致锚点（缺齿、雀斑群、银色发缕、眉间疤、一颗痣） - 锁定：面部几何、肤色底调、头发行为 — 这些永不漂移 ════════════════════════════════════════════════════════════ 简报 — 每个镜头填写一次。上述引擎不变。═══════════════════════════════════════════════════════════ 领域 :: 什么样的创作者 / 这个画面用于什么 主体逻辑 :: 推导 — 该领域对身体、手和衣橱的影响；履历证据（老茧、污渍、疤痕、晒痕）；一件静静待在背景中的真实性道具 瞬间 :: 单一节拍（动作中 / 过渡 / 休息）+ 表情 + 视线方向（偏离镜头通常更显得自然抓拍） 光线 :: 从菜单中选择一种 — 它决定阴影、高光、调色 场景 :: 环境，居住感，带有使用痕迹 + 一个模糊的生命迹象（路过的陌生人、撕了一半的贴纸） 光学 :: 构图距离（决定分辨率）+ 焦距 + 光圈 + 比例 + 既定调色 今日表面 :: 可选 — 汗 / 雨 / 蒸汽 / 无 + 今天可见的那一处诚实瑕疵 标尺 :: 一位[相关专家]相信[技艺]，一位粉丝相信[质感]，而放大到 200% 时皮肤仍然读作皮肤 — 没有高光，没有那一刻不配拥有的光滑。仅照片，无排版。``` **为了证明它不局限于健身题材 — 同一引擎，完全不同的主体，只重新填写简报：** ``` 人设种子 ::= Idris Okafor + 34 + 英籍尼日利亚裔 + 难忘特征：左眉上一道瘢痕疙瘩疤；大笑时露出的一颗金牙门齿；短发，太阳穴处有一小块早生白发 - 锁定：面部几何、深暖底调、脸颊处长势斑驳的胡须 简报 :: 领域 :: 美食创作者 — 一幅带菜的肖像，抓拍在品尝中 主体逻辑 :: 多年后厨岁月 = 前臂的小烫伤疤、老练的握刀姿势、甲床里的面粉幽灵；背景中一件溅满酱汁的围裙和一把停在砧板上的刀 瞬间 :: 他刚举起勺子要尝，闭上眼睛，不由自主地微微点头表示认可 — 视线在食物上，绝不看镜头 光线 :: 窗边 — 从左侧斜射；脸的右侧落入柔和的阴影；窗户在他近侧眼睛里呈一个干净的长方形 场景 :: 使用中的家常厨房 — 他身后一只冒着热气的平底锅，一块带碎屑的砧板，边缘有一只朋友模糊的手 光学 :: 肖像 / 胸部以上 → 分辨率保持毛孔和胡须纹理锐利；50mm f/2；4:5；暖中性调色，无橙色过饱和 今日表面 :: 前额上轻微的厨房热气光泽；一个指节上的小划痕作为今日的诚实瑕疵 标尺 :: 一位厨师相信刀工，一位粉丝相信蒸汽，而放大到 200% 时皮肤仍然读作皮肤 — 烫伤疤、胡须、厨房光泽 — 没有厨房不配拥有的高光。仅照片，无排版。```
