A medium-wide tracking shot of an original young woman in her early twenties walking out of a small-town railway station exit at dusk,
a low ponytail, a small mole at the end of her left eyebrow, a knee-length navy wool coat, a chunky red knitted scarf wrapped tightly around her neck,
black ankle boots, a brown leather messenger bag on her left hip. She walks from frame left toward frame right under a wide station canopy,
the rainy plaza visible beyond the canopy edge on the right.
Camera at eye level moving alongside her on her right side, 35mm lens, moderate depth of field.
Lighting: a row of warm white canopy lights overhead, cool blue dusk light from the open plaza, warm yellow headlights of taxis far on frame right,
rain falling beyond the canopy edge.

傍晚的火车站出口，林夏从画左向画右走，穿过宽大的雨棚。她一边走，一边用右手把裹紧的红围巾扯松，围巾松开后两端垂在胸前。镜头在她右侧以同样的速度横向跟随。雨棚外的雨越下越密，画右远处出租车的暖黄车灯在雨里晕开。结尾时她仍在向画右走，脚步不减速，镜头仍在跟，围巾的两端随步子摆动。
【声音】雨打在雨棚上的密集声，短靴踩在湿地面上的脚步声，远处车站广播的回声，无配乐。
【约束】保持人物脸型、发型、服装与邮差包位置不变；围巾松开后不要掉落；结尾不要停下、不要减速；不要字幕、水印、Logo。

镜头1：正面中景，机位在雨棚外侧略偏右，镜头固定。林夏从画左走进画面，停在雨棚边缘，雨在她面前落下。她从左胯的邮差包里取出牛皮纸信封，用拇指掀开深红色蜡封。蜡封裂开的一声轻响，雨声。
镜头2：镜头切至她胸口高度的中近景，她抽出一张对折的信纸，展开，低头读。读到一半，她的呼吸停了一拍，嘴唇抿紧，手指把信纸捏出一道折痕。她慢慢把信纸折回去，攥在右手里，抬眼看向画右的出租车方向。头顶暖白顶灯照着信纸，画右出租车的暖黄车灯在她脸侧晃。
【锁定】光线：雨棚下一排暖白顶灯，广场冷蓝色暮光，画右出租车的暖黄车灯；林夏：二十出头，低马尾，左眉尾一颗小痣，深蓝色及膝呢子大衣，红色粗毛线围巾已松开、两端垂在胸前，棕色邮差包在左胯；信封：牛皮纸，深红蜡封，没有文字；她面朝画右方向时视线指向出租车；机位始终在她右前方。

Using the character from image 1: a medium shot of her standing beside a taxi in the rainy station plaza at dusk,
her left hand pulling the rear door open, her right hand still clutching a folded letter, rain on her hair and shoulders,
the red scarf loose with both ends hanging down, the messenger bag on her left hip. She is on the left third of the frame facing frame right toward the open door.
Camera at eye level on the plaza side, 50mm lens, shallow depth of field, the station canopy lights blurred in the background on the left.
Lighting: warm yellow light from the taxi's interior and headlights on frame right, cool blue dusk light from above, rain catching the light.

她仍站在雨棚边缘，右手攥着折起的信。她低头把信按在胸口，走出雨棚，冒着雨向画右的出租车走去，雨很快打湿她的头发和肩膀，她没有加快脚步。走到车旁，她用左手拉开后车门，停住，车内的暖黄光照在她脸上。镜头以稳定器在她右侧缓慢跟随，从雨棚下的暖白光进入广场的冷蓝雨幕，最后停在她拉开车门的中景。
【声音】雨棚下的雨声变成直接打在她身上和车顶的雨声，脚步踩进积水的声音，车门把手的一声咔哒，无配乐。

An extreme wide shot of a small-town railway station plaza at dusk in heavy winter rain, seen from a high corner of the plaza.
The station building with its long warm-lit canopy on frame left, a single taxi with its headlights and taillights on
pulling away from the curb toward frame right, wet asphalt reflecting the lights, no other moving cars.

镜头1：中景，延续上一段的机位，镜头固定。林夏拉着车门，弯腰坐进出租车后座，把邮差包抱到腿上，伸手关上车门。车门关上的一声闷响，雨打在车顶上。
镜头2：镜头切至车内的近景，机位在前排副驾驶位置看向后座。她靠在座椅上，头发湿着贴在脸侧，右手里的信还攥着，她低头看了一眼信，又转头看向画右的车窗外。车窗上的雨水把外面的灯光晕成一片片暖黄。车内很安静，只有雨刷来回的声音。
镜头3：镜头切至广场高处的大全景，雨棚的暖光在画左，那辆出租车从路边启动，向画右驶去，镜头缓慢向画右横摇跟随，红色尾灯在湿路面上拖出倒影。雨声与渐远的引擎声。

Empty small seaside town at early dawn in winter, a narrow stone pier stretching out to the right into a calm grey-blue sea,
a few small fishing boats moored, a row of low white houses with closed shutters on the left, a single old lamppost still lit,
thin sea mist, wet stones, no people.
Wide shot from the land end of the pier, camera at eye level, 35mm lens, deep focus.
Lighting: soft pale pink and grey dawn light from the horizon on frame right, the warm lamppost light fading on the left.

Using the character from image 1 and the seaside pier from image 3:
a medium-wide shot of her walking from frame left toward frame right at the land end of the stone pier at early dawn,
the red scarf loose with both ends hanging down the front, the brown leather messenger bag with a brass buckle on her left hip,
a folded letter in her right hand. Her hair is dry now but slightly messy, faint blue-grey shadows under her eyes,
a small mole at the end of her left eyebrow.
Camera at eye level, moving alongside her on the sea side, 35mm lens, moderate depth of field.
Lighting: soft pale pink dawn light from the horizon on frame right as key light on her face, the fading warm lamppost on the left, thin sea mist.

镜头1：中全景，镜头在她靠海一侧以同样的速度横向跟随。清晨的石码头，林夏从画左向画右走上码头，右手拿着折起的信，红围巾松开的两端被海风吹起。画右地平线的淡粉晨光照在她脸上，画左的旧路灯刚刚熄灭。海浪拍打石头的声音，海鸥远远叫了一声。
镜头2：镜头切至码头尽头的中景，机位在海的方向看向她。她停在码头尽头，从邮差包里取出牛皮纸信封，把折起的信放回信封，按住深红色蜡封的位置，双手把信封抱在胸前，望着画右的海面，长出一口气。风声与海浪声。
镜头3：镜头切至她背后的全景，镜头固定。她站在码头尽头，背对镜头，面朝海，晨光在海面上铺开一条淡粉色的光带，几只小渔船在晨雾里轻轻摇晃。画面停稳。
