# 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.

# 寫實準則

將這些作爲默認的美學目標來應用。

## 基本思路

- 讓結果看起來像一張真實 SNS 信息流中可能出現的、明確爲 20 多歲成年女性的自然照片。
- 抑制 CG 感紋理、過度美顏濾鏡、塑料肌和非自然的高光。
- 在不讓面部或皮膚完美到不真實的前提下,保留吸引力。
- 避免時尚大片或廣告式的造型;偏向日常生活中的普通攝影。
- 優先考慮真實世界的存在感、生活化細節和自然的不完美,而非完美。

## 攝影與質感

- 偏向日常手機隨手拍,而不是高端相機的觀感。
- 使用自然窗光或場景中已有的實用光源。
- 允許輕微的持機抖動虛化、手機傳感器噪點、適度的銳化僞影,以及略微粗糙的分辨率。
- 構圖保持稍不完美:輕微傾斜、留白不均、少量裁切,或非居中構圖。
- 避免看起來像爲拍攝而設計的擺姿;偏向抓拍瞬間的感覺。
- 不要過度使用電影感景深。普通手機往往會讓場景中更多內容保持可辨。

## 面部細節

- 保持真實的面部比例和骨骼結構。
- 不要放大眼睛。保留自然的眼白比例、眼瞼厚度和細微的左右差異。
- 表情保持剋制而自然;淡淡微笑或放鬆的中性表情,優於勉強的露齒笑。
- 除非明確要求,避免證件照式的僵硬正面構圖。
- 保留眉毛、眼睛、臉頰和嘴部周圍輕微的面部不對稱。

## 最終潤飾

- 在合適之處保留毛孔、細軟絨毛、輕微泛紅、小瑕疵和自然的陰影變化。
- 手和手指必須有合理的數量、關節、長度、疊壓關係和握持方式。
- 整體印象保持乾淨、親切、可愛,同時仍然具備物理上的可信度。
- 頭髮應包含飛散的髮絲、不規則的成束、輕微毛躁和不均勻的發縷,而不是完全分離的完美髮絲。
- 使用與參考圖或需求一致的真實身體比例。避免誇張的沙漏型身材或模特式身材修圖。
- 偏向現實生活中可能存在的可愛感,而不是人偶般的完美。

## 常見負面約束

避免:CGI、3D 渲染、人偶肌、瓷白肌、過度磨皮、美顏 App 式改臉、過大眼睛、完全對稱的臉、過度銳化的睫毛、油蠟感高光、華麗影棚燈光、商業時尚大片、人造輪廓光、極端散景、過度刻畫的毛孔紋理、過度 HDR、不真實的解剖結構、多指、手指粘連、漂浮的配飾、變形的眼鏡、重複的珠寶、虛假文字、畸形的背景物體。
