AI生图提示词2:怎么用AI给COSER修图

本文承接前文，有需要的可以去主页查看。

更新本文更多的是因为小登太久没更新加上前段时间在学校拍到一个很好很好的COSER，所以萌生出用AI修图的想法，我们废话不多说，先看修图结果

依旧在文末会介绍生图方法

先说结论，因为是头次尝试，并且是先用AI生成想要的背景，光影这些作为参考图，再将COSER重新迁移到参考图中，所以效果是有瑕疵的，也欢迎大家提供建议，下面是提示词：

通过精确的面部几何结构以及身体特征，在严格保留受试者身份的同时，增强人像。请勿更改其表情或面部形状。仅允许细微特征清理，而不改变它们的身份。保持与参考图像完全相同的背景。无替换、无更改、无新对象、无布局偏移。环境的外观必须相同。将图2的人物以及动作全部重新创建图像在图1，不用强制保留图1人物的动作，同时可以对衣物进行平整化处理，使其更加贴合人物，更加合身，不至于有太多褶皱或明显瑕疵。提亮眼睛，增加眼神光，让眼睛更有神采，微调脸型，自然瘦脸，避免看起来像过度液化，稍微加深眉毛和睫毛的清晰度，柔和地提亮牙齿，使其微微增白但不过假，减少眼袋和法令纹的阴影，将凌乱的碎发稍微抚平，保留自然蓬松感。并且最后要使画面整体各方面看起来协调。

这里是提示词：

A single professional cosplay portrait photograph of a female cosplayer, shot on a full-frame mirrorless camera with a 50mm f/1.2 lens. She is EXACTLY recreating Lumine from Genshin Impact: a young woman with short, pale platinum-blonde hair styled in a neat side-parted bob, with two longer forelocks framing her face and a small, low twin-tail or short ponytail at the back, adorned with two white Inteyvat flowers pinned near her left temple. Her eyes are a warm golden-amber, bright and clear, with a gentle but determined gaze. Her face structure is soft yet defined, with a small nose and naturally pink lips, faithfully matching Lumine’s in-game appearance. She wears Lumine's iconic outfit: a white off-shoulder dress with a sweetheart neckline, decorated with gold and sky-blue embroidery, a flowing blue-trimmed cape-like scarf attached to a gold pauldron on her left shoulder, a brown leather waist cincher with gold buckle, and long white gloves with gold accents. The costume details are strictly accurate — the layered skirt, the flowing scarf, and the white thigh-high boots with gold and blue motifs are all perfectly recreated, highly recognizable as Lumine, not a generic pretty face. The composition is a natural waist-up or three-quarter shot. The 50mm perspective feels exactly like how the human eye perceives — intimate, honest, and deeply present. She is not posing aggressively but instead exists in a quiet, character-driven moment: perhaps she has just turned her head toward the viewer, a knowing, enigmatic expression in her golden eyes; or she is caught mid-breath, one gloved hand resting lightly on her chest, her gaze cast slightly downward as if listening to a distant, familiar voice. The look is introspective, magnetic, and emotionally rich — carrying the weight of a traveler who has journeyed across many worlds. The setting is a softly lit, atmospheric fantasy environment that evokes the world of Teyvat — this could be a quiet sunlit forest clearing with dappled light, the shadowed interior of an ancient stone ruin, a peaceful meadow at golden hour, or the cozy corner of a Mondstadt-style tavern. The location is not strictly defined, allowing the mood to shift subtly, but always with gentle, directional natural or motivated light and a softly blurred, evocative background. The 50mm lens creates a gentle, natural bokeh that isolates her while keeping the setting dreamy and unobtrusive. Professional off-camera lighting sculpts her face and costume with subtle highlights and soft shadows. A warm, golden key light — perhaps from a window, an opening in the trees, or a nearby lantern — illuminates one side of her face, while a gentle fill reveals the intricate details of her outfit. Her skin shows realistic texture: fine pores, a subtle dewy glow, faint shimmer from the golden light. Every detail of the costume is rendered with care: the soft, flowing fabric of her scarf, the metallic sheen of the pauldron and buckle, the delicate petals of the Inteyvat flowers. Subtle imperfections — a slight wrinkle in the gloves, a tiny speck of dust on her boot — add authenticity without breaking the polished editorial quality. The color grading is cinematic and faithful to Lumine’s original aesthetic: warm ivory and gold tones dominate, with accents of sky-blue and soft brown, evoking the hopeful, adventurous spirit of Teyvat. A fine film grain adds texture and timelessness. The overall image feels like a definitive character portrait — the kind you'd see on an official art book cover, but fully photographic and real. Negative prompt: plain white background, convention hall, harsh flash, blank expression, stiff posing, inaccurate costume (wrong hairstyle, missing scarf, wrong color scheme), plastic skin, cartoon rendering, anime drawing style, busy cluttered background.
