感官体验描述生成

以下为可直接用于Stable Diffusion的提示词方案，兼顾叙事细节与可控标签，并强化“暮色海港、逆光渔民举网、水面反光、粗颗粒胶片感”的质感与氛围。

主提示词（叙事型）
- 暮色压在海港之上，天光像被海风打磨过的铜，残阳从地平线背后缝隙渗出，只留下刺目的逆光火边。一个饱经风浪的渔民立在湿滑的码头边，他沉着发力，把沉重的渔网从水面缓缓举起；密密的水珠在空中炸裂，像细小的流星沿着网眼弧线飞溅，沾湿他的衣襟与掌纹。远处锈红的渔船与黑影桩柱排成层层叠叠的剪影，粗糙的缆绳斜切画面，带出方向与力量。海面被风揉皱，靛蓝与琥珀交错，反光像碎金在波纹间游移，偶有海鸥低掠，叫声被盐雾与柴油味糅成一缕苦咸的气息。画面整体以逆光勾出人物轮廓光，亮部有细微晕光与卤光，暗部深而有细节；粗颗粒的高ISO胶片质感与推片后的强对比让色温在冷蓝与暖橙之间拉扯，像潮汐互撞。35mm视角，低机位，三分法构图，前景湿润木板与绷紧的缆绳提供触感，背景轻微虚化以衬托锐利的水滴与网线；轻微暗角与胶片颗粒在空气中沙沙作响，像在耳畔嗡鸣的晚风。

精炼提示词（标签型）
- 暮色海港，逆光，剪影渔民，举起的渔网，水滴飞溅，水面金色反光与靛蓝阴影，海鸥，锈蚀渔船，系船桩与缆绳引导线，低机位，三分法，广角35mm视角，湿润木质码头，薄海雾，冷暖对比，戏剧化天空，真实写实摄影
- 粗颗粒胶片感，高ISO颗粒，推片，对比增强，轻微晕影，细微卤光（类似Cinestill式高光晕），边缘暗角，色彩克制，质感突出，水滴与网线锐利，背景轻微运动模糊
- 质感关键词：盐雾、潮湿、粗粝、金属锈斑、湿光、风感

负面提示词
- 低清晰度，严重噪点（数字噪点感），过度HDR，刺眼光晕条纹，过度饱和，卡通，动漫，3D渲染风，塑料质感，AI瑕疵，畸形人体，多余肢体，扭曲手部，重复渔网，错误透视，拼接痕迹，文字，水印，Logo，涂抹感，失焦主体

建议参数（可按需要微调）
- 宽高比：3:2 横向（如 1216x816 或 1344x896）
- 风格/模型倾向：写实摄影/胶片质感取向
- 采样器与步数：DPM++ 2M Karras 或 Euler a，步数 28–36
- CFG：5–7（偏写实与环境光保留）
- 种子：固定以复现；随机以探索变化
- 细化建议：如使用Refiner或后期插件，适度提升高光卤光与颗粒，控制高光不过曝；曲线压暗阴影但保留暗部细节

使用说明
- 如想更强“颗粒与推片”效果，可在正向提示中额外加入：高ISO 1600–3200、push processed、grainy 35mm film、subtle halation。
- 若画面过亮或逆光不足，增加：强逆光、rim light、silhouette emphasis；若太平滑，增加：gritty texture、wet surfaces、salt mist。

Primary prompt (photorealistic poster)
Minimalist spring poster for an eco-friendly personal care brand; a soft, trustworthy, natural atmosphere in a palette of warm off‑white and light green. Centered still life: a single tall recycled matte‑glass bottle with a bamboo pump, milk‑glass translucency, pale sage liquid glowing softly inside, fine dew beading like morning mist. The bottle rests on an uncoated off‑white paper plinth with subtle fiber texture; a few tender spring leaves lie nearby, their edges catching a whisper of light. Background fades from creamy ivory to celadon, with delicate dappled leaf‑shadow bokeh, as if sunlight drifted through fresh foliage after rain. Airy humidity, a breath‑thin curl of vapor, the room smelling like clean linen and new grass. Composition is calm and spacious with generous negative space above and around the subject for copy, edges immaculate, grid‑true, no clutter. Lighting is diffuse skylight with a gentle back rim, soft muslin bounce, ultra‑soft shadows; translucent highlights along the glass edges and a quiet sheen on the bamboo; no harsh speculars. Product photography, editorial advertising, minimalism, Japandi/Scandinavian restraint, eco luxury. Medium‑format look, 85mm equivalent, f/4 shallow depth, crisp focus on the bottle front, natural color, low contrast, silky micro‑textures. Materials feel tactile and honest: uncoated paper, recycled glass, linen; matte, breathable, serene. Ultra‑clean, high‑detail, 4k poster, soothing, credible, spring‑fresh.
