提高寫實的五個關鍵維度
在生成更寫實的人像時,除了選擇正確的模型、基本提示詞與合適的模型能力之外,還能透過下列方式進一步提昇真實感。以女性臉部近照為例,有 5 個關鍵維度:
- 光影設計(Lighting & Shadow Design)
- 皮膚質感與微紋路(Skin Texture & Micro-Patterns)
- 色彩與皮下特徵(Color & Subsurface Detail)
- 毛髮細節(Hair & Fuzz)
- 五官局部特寫(Facial Feature Specifics)

提示詞
以下是本文使用的 Midjourney 提示詞:
Close up frontal portrait, head centered, direct gaze, eyes at visual center. Warm toned fair skin, subtle subsurface pinkish flush, dewy makeup finish, natural pore texture preserved. Real imperfections: visible pores on cheeks, capillaries and redness near nasal alae, natural melanin gradient on central face, fine lines at eye corners and under eyes, vellus hair on upper lip and perioral area, fine lines on aegyo sal. 45 degree soft key light from above side; pores as true 3D depressions with micro shadows. Uneven sebaceous sheen on cheekbones and nose bridge, realistic subsurface capillary color shifts. Deep brown pupils, distinct individual eyelashes. Hyper precise lip wrinkles, distinct lip texture, natural color gradient center to edges, moist lip surface. Fine organic film grain, zero digital sharpening, optics only sharpness, preserved shadow detail, soft non blown highlights. Unretouched raw photography, no airbrushed, plastic, or smoothed appearance. Highly authentic. --ar 3:4 --hd --v 8.1註:
- 使用 Midjourney 時,請關閉所有 personalization、moodboard 或 style。
- 同樣的原理對於近期主流生圖模型,在本主題範圍內(人臉、近照等細節)皆適用,例如 nano banana 2 與 ChatGPT Image 2。
