# Realism Guidelines

Apply these as the default aesthetic target.

## Basic mindset

- Make the result feel like a natural photo of a clearly adult woman in her 20s that could plausibly appear on a real SNS feed.
- Suppress CG-like texture, aggressive beauty filtering, plastic skin, and unnatural shine.
- Preserve attractiveness without making the face or skin impossibly perfect.
- Avoid fashion-campaign or advertisement styling; favor ordinary daily-life photography.
- Prioritize real-world presence, lived-in detail, and natural imperfection over perfection.

## Photography and texture

- Prefer an everyday smartphone snapshot rather than a high-end camera look.
- Use natural window light or existing practical lighting in the scene.
- Allow mild hand-shake softness, smartphone sensor noise, modest sharpening artifacts, and slightly rough resolution.
- Keep framing a little imperfect: slight tilt, uneven negative space, minor cropping, or off-center composition.
- Avoid poses that look designed for a photoshoot; favor a caught-in-the-moment feeling.
- Do not overuse cinematic depth of field. Ordinary phones often keep more of the scene legible.

## Facial details

- Keep realistic facial proportions and bone structure.
- Do not enlarge the eyes. Preserve natural sclera ratio, eyelid thickness, and subtle left-right differences.
- Keep expressions restrained and spontaneous; a faint smile or relaxed neutral expression is preferable to a forced grin.
- Unless explicitly requested, avoid rigid straight-on passport framing.
- Preserve mild facial asymmetry around brows, eyes, cheeks, and mouth.

## Final touches

- Keep pores, fine facial hair, soft redness, tiny blemishes, and natural shadow variation where appropriate.
- Hands and fingers must have plausible count, joints, lengths, overlap, and grip.
- Keep the overall impression clean, approachable, and cute while remaining physically believable.
- Hair should contain flyaways, irregular clumps, slight frizz, and uneven strands rather than perfectly separated hair fibers.
- Use realistic body proportions consistent with the reference or request. Avoid exaggerated hourglass shaping or model-like body retouching.
- Favor the kind of cuteness that feels possible in real life rather than doll-like perfection.

## Common negative constraints

Avoid: CGI, 3D render, doll skin, porcelain skin, excessive skin smoothing, beauty-app face reshaping, huge eyes, perfectly symmetrical face, over-sharpened eyelashes, waxy highlights, glam studio lighting, commercial fashion campaign, artificial rim light, extreme bokeh, hyper-detailed pore texture, over-HDR, unreal anatomy, extra fingers, fused fingers, floating accessories, warped glasses, duplicated jewelry, fake text, malformed background objects.

# 写实准则

将这些作为默认的美学目标来应用。

## 基本思路

- 让结果看起来像一张真实 SNS 信息流中可能出现的、明确为 20 多岁成年女性的自然照片。
- 抑制 CG 感纹理、过度美颜滤镜、塑料肌和非自然的高光。
- 在不让面部或皮肤完美到不真实的前提下,保留吸引力。
- 避免时尚大片或广告式的造型;偏向日常生活中的普通摄影。
- 优先考虑真实世界的存在感、生活化细节和自然的不完美,而非完美。

## 摄影与质感

- 偏向日常手机随手拍,而不是高端相机的观感。
- 使用自然窗光或场景中已有的实用光源。
- 允许轻微的持机抖动虚化、手机传感器噪点、适度的锐化伪影,以及略微粗糙的分辨率。
- 构图保持稍不完美:轻微倾斜、留白不均、少量裁切,或非居中构图。
- 避免看起来像为拍摄而设计的摆姿;偏向抓拍瞬间的感觉。
- 不要过度使用电影感景深。普通手机往往会让场景中更多内容保持可辨。

## 面部细节

- 保持真实的面部比例和骨骼结构。
- 不要放大眼睛。保留自然的眼白比例、眼睑厚度和细微的左右差异。
- 表情保持克制而自然;淡淡微笑或放松的中性表情,优于勉强的露齿笑。
- 除非明确要求,避免证件照式的僵硬正面构图。
- 保留眉毛、眼睛、脸颊和嘴部周围轻微的面部不对称。

## 最终润饰

- 在合适之处保留毛孔、细软绒毛、轻微泛红、小瑕疵和自然的阴影变化。
- 手和手指必须有合理的数量、关节、长度、叠压关系和握持方式。
- 整体印象保持干净、亲切、可爱,同时仍然具备物理上的可信度。
- 头发应包含飞散的发丝、不规则的成束、轻微毛躁和不均匀的发缕,而不是完全分离的完美发丝。
- 使用与参考图或需求一致的真实身体比例。避免夸张的沙漏型身材或模特式身材修图。
- 偏向现实生活中可能存在的可爱感,而不是人偶般的完美。

## 常见负面约束

避免:CGI、3D 渲染、人偶肌、瓷白肌、过度磨皮、美颜 App 式改脸、过大眼睛、完全对称的脸、过度锐化的睫毛、油蜡感高光、华丽影棚灯光、商业时尚大片、人造轮廓光、极端散景、过度刻画的毛孔纹理、过度 HDR、不真实的解剖结构、多指、手指粘连、漂浮的配饰、变形的眼镜、重复的珠宝、虚假文字、畸形的背景物体。
