§ 2 · 摄影Prompt完整体系

2.1 光线Prompt库

自然光系：

黄金时刻（日出/日落）: "golden hour sunlight, warm directional light from [left/right], long shadows, 2700K color temperature"

蓝调时刻（日出前/日落后）: "blue hour light, soft diffused cool light, 5000K, subtle gradient sky"

正午硬光: "harsh midday sunlight, high-contrast shadows, top-lit, overhead directional"

阴天柔光: "overcast sky, soft diffused light, no harsh shadows, even exposure, melancholic mood"

窗户光: "window light from left, directional soft light, natural falloff, Rembrandt lighting pattern"

人工光系：

霓虹夜景: "neon reflections on wet pavement, cyan and magenta practical lights, 85mm f1.4 bokeh, night city atmosphere"

低调戏剧光: "low key lighting, single source key light, deep shadows, 70% of frame in darkness, noir mood"

暖色室内: "warm tungsten practical lights, 3200K, cozy interior, candle-like quality, slight flicker"

冷峻科技感: "cool blue LED panels, high-tech environment, 6000K, clean sharp shadows"

摄影棚伦勃朗: "Rembrandt lighting, soft box key 45° above left, fill ratio 1:4, catchlight in eyes"

2.2 摄法Prompt精确语法

推进（情绪聚焦）:
"slow dolly in, starting medium shot ending medium close-up, 8-second duration"

拉出（孤独/揭示）:
"slow dolly out, starting close-up ending full shot, reveals isolated figure in vast environment"

横移跟拍（跟随动作）:
"tracking shot following subject, smooth gimbal movement, maintains same framing throughout"

弧线环绕（360°强调）:
"slow arc shot around subject, 180-degree rotation, keeping subject centered"

手持（真实感/紧张）:
"subtle handheld movement, slight organic camera shake, documentary feel, avoid excessive shakiness"

升降（上升-史诗；下降-压迫）:
"slow crane up, starting eye level ending elevated bird's eye view"

对焦切换:
"rack focus from foreground object to background subject, shallow depth of field"

锁定静止（对话/沉默）:
"static locked shot, tripod stability, no camera movement"

2.3 视觉风格Prompt模板

电影院线质感：

"cinematic 2.35:1 aspect ratio feel, anamorphic lens flares, shallow depth of field f1.4, 
film grain texture, Kodak Vision 500T color palette, warm shadows, muted highlights"

现代商业感：

"commercial photography aesthetic, clean bright exposure, saturated colors, 
sharp throughout f8, professional studio lighting, contemporary look"

复古胶片感：

"Super 8 film aesthetic, warm color shift, heavy grain, vignette edges, 
faded highlights, 1970s home movie feel"

港风新浪潮：

§ 9 · Scenario Examples

场景1：情绪匹配摄影方案

用户： "男主在雨夜独自坐在城市高处，思念远方的人。给我一个完整的摄影方案。"

AI摄影指导：

情绪目标： 孤独感+诗意忧郁，避免廉价伤感

完整摄影方案：

推荐Prompt（镜头3）：

@男主(ref) sitting on rooftop edge, looking at distant city, rain falling, 
medium close-up slowly dollying out to reveal isolated figure against vast city skyline, 
neon reflections: cyan and amber, 50mm f2 bokeh city lights, 
cinematic desaturated teal grade with warm face highlights, 
rain drops caught in backlight, melancholic mood, avoid jitter

场景2：商业广告摄影方案
