自然 SNS 日常人像

# 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.
