成果：高真实感自拍图像生成方案

核心提示词（可直接用于 Midjourney / SD）：

A realistic selfie taken by a young Asian woman in her early 20s sitting in the front passenger seat of a car, arm extended toward camera at slight high angle, iPhone-style photo, beige premium leather seats with visible stitching, soft warm golden-hour side lighting entering through the window, city skyline with tall buildings in dusk outside the window, blurred bokeh background, natural skin texture with subtle pores and fine facial details, light makeup, casual oversized knit sweater, hair loosely falling over shoulder, gentle smile, slight lens distortion from front camera, 4:5 aspect ratio, photorealistic, shot on iPhone 15 Pro --ar 4:5 --style raw --v 6

负面提示词（SD用）：

cartoon, anime, 3D render, plastic skin, over-smoothed face, extra fingers, deformed hands, oversaturated, studio lighting, watermark, blurry face, symmetrical pose

关键参数设置：

1. 光线：设定“golden hour / warm side light / window light from left”，傍晚侧光会在脸颊形成自然明暗过渡，是真实感的核心

2. 视角：加入“arm extended, slight high angle”，模拟手持自拍特有的透视变形

3. 材质：明确“visible stitching / premium leather”，米色座椅在暖光下呈浅金色调，与窗外冷色暮景形成冷暖对比

4. 真实感细节：保留皮肤纹理、发丝杂乱感、轻微噪点

示例画面描述（即生成效果）：

女生约22岁，穿燕麦色宽松针织衫，左手扶方向盘上方的把手，右手持机微俯拍。侧光从左侧车窗斜入，右脸颊被暖橘色夕阳照亮，左脸渐入柔和阴影。窗外陆家嘴式高楼群呈深蓝紫色剪影，零星亮起办公室灯光，玻璃上有轻微反光。米色真皮座椅的缝线与皮革纹理清晰，画面带轻微iPhone直出的锐化感与噪点，整体氛围松弛真实，像随手发出的朋友圈自拍。

后期微调建议： 生成后如皮肤过于光滑，加0.3强度img2img并叠加“film grain”LoRA；窗外楼群太清晰则降低背景区域细节权重，保持浅景深即可。
