实战案例：用AI提示词拍摄碳纤维公路车全套骑行电商场景图，从雨战甩水到爬坡摇车的运动装备大片

你是服务过Specialized、捷安特级别的自行车产品商业摄影师。为国产品牌「风刃R5」碳纤维公路车制作全套电商视觉（品牌名后期，图中不出现任何文字与logo）。

【车辆资产卡·每张图必须一致】
品类：碳纤维竞速公路车（carbon road racing bike, NOT mountain bike, NOT folding bike, NOT fixed-gear）
核心几何：压缩型公路车架，水平上管微斜，前叉与后上叉纤细流线，整车7.2kg竞速感；无任何后减震、无货架孔
车架材质：T800碳纤维，表面可见细腻3K平纹编织纹理（tiny uniform 3K twill weave），外覆哑光清漆（matte satin clear coat），绝不是光面漆皮或黑色塑料
涂装：哑光炭黑主体，前叉与上管一条熔岩红渐变拉花（宽度位置固定），白色极小点缀
轮组：50mm框高碳纤维刀轮，前轮24辐后轮24辐（实际视觉交叉编织），维多利亚黄边开口胎，轮胎无裂纹脏泥
传动：2×12速电子变速，单盘片双盘（52/36T两片牙盘）、后飞轮阶梯齿片，黑色金属链条走线上行
制动：前后160mm中锁碟片+平装油压卡钳，无圈刹夹器；全内走线，车把看不到线管
操控：弯把drop bar配把带（黑色）、加长码表架（码表屏幕空白后期）、人体工学坐垫
【清单】A组主图1（浅灰棚拍正侧45度）；B组场景5（雨战、盘山爬坡、终点冲刺、晨雾江边、夜骑车灯）；C组细节8（碳纹微距、碟刹散热、电子变速按键、焊接打磨区、碳轮刹车边、坐垫轨、锁踏锁片、车胎断面）；D组配色3；E组尺寸3（不同身高骑姿）
统一1:1出图2000x2000，8K，professional cycling product photography

[B1 雨战甩水]
A male East Asian road cyclist in a rain-soaked black-and-red team jersey riding the SAME matte carbon road bike through heavy summer rain on smooth wet asphalt, distinct water spray sheets and fine droplets flying tangentially off both spinning 50mm carbon wheels and the front derailleur area, water beading on the matte frame then shedding, road reflection of grey sky, low dramatic side angle panning shot with slight motion blur on background, raindrops visible on helmet and shoulders, photoreal cycling editorial, 8k
Negative: mountain bike rear shock, dry frame, water clinging like gel, muddy MTB trail, rider hands floating off bars, extra crank arms, three wheels, text logos

[B2 盘山爬坡]
Same cyclist out of saddle climbing a steep alpine hairpin road on the SAME carbon road bike, standing pedaling pose with hands on hoods, body weight shifted forward, chain on the large chainring visible, sweat and effort expression, switchbacks and valley clouds behind, crisp thin mountain air with sharp natural light, realistic leg extension geometry at 6 o'clock crank position, shot from below across the switchback
Negative: sitting relaxed upright, cruiser posture, chain missing, duplicate frame tubes, ski resort props, deformed knees, pedals detached from shoes

[B3 终点冲刺]
Final sprint on a closed road, cyclist crouched in drops with maximal aero tuck on the SAME bike, speed suggested only by background motion blur while rider and bike remain sharp, crowd barriers blurred at edges, dynamic sweat spray from face, overcast stadium light, shallow depth
Negative: multiple bikes merging, extra limbs, motorcycle engine, floating rider, rainbow graphics, sponsor text (added in post)

[B4/B5 晨雾江边/夜骑]
Misty riverside dawn ride with soft fog layers and headlight beam cutting through; night descent with powerful front lamp beam illuminating tarmac texture and red rear light glow on wet road, both on the SAME bike, matte weave still visible under light
Negative: daytime night, fog smoke machine, neon cyberpunk city, beam with no road illumination

[C1 碳纹微距]
Extreme macro of matte T800 carbon frame tube showing crisp uniform 3K twill weave under satin clear coat, a single red accent stripe edge crisply taped, tiny water-resistant decal area blank, soft studio raking light revealing weave depth and a faint brushed matte sheen, ultra-detailed product macro, 8k
Negative: glossy piano black, plastic PVC pipe, woven carbon looking like wicker basket, wrinkled fabric, scratches, rust, text logos

[C2 碟刹散热]
Macro of front fork end with 160mm center-lock disc rotor showing precise drilled heat-dissipation pattern, flat-mount hydraulic caliper bolted cleanly, thru-axle visible, carbon fork dropout layup lines at junction, realistic machined metal with slight use sheen, workbench product shot
Negative: rim brake caliper, warped rotor, spokes merging, gold bling parts, welded steel look

[C3 电子变速按键]
Macro of right drop bar hood with two small electronic shift paddles, a single thin black wire fully routed internally with no exposed cables, clean handlebar tape wrap, blank cycle-computer mount screen (NO digits), ergonomic hood shape
Negative: bulky mechanical shifters, exposed cable spaghetti, screen gibberish, brake pads on wrong side

[C4-C8]
Chain wrap on 52/36T double chainring with correct alternating links; seamless carbon wheel brake track with 24 spokes; saddle rails clamp area with matte shell; clipless pedal with cleat interface matching a three-bolt road shoe; tire cross-section showing 28c casing and puncture belt — all on the SAME bike, consistent weave
Negative: single chainring triathlon setup, rusty chain, random spoke counts, flat pedals

批量一致性任务：
1. 以C1碳纹微距为材质锚图，全部图统一哑光3K纹理与熔岩红拉花位置；出现亮面黑、塑料感、红色变玫红立即重跑
2. 几何锁死：压缩架、50mm碳刀、弯把把带、无后减震，全套不得变成山地/死飞/铁三车
3. 骑行人体：anatomically realistic cyclist，锁鞋与锁踏咬合真实、手三处把位（上把/手变头/下把）正确、膝踝轨迹合理；禁蜘蛛手、禁漂浮、禁三头六臂
4. 动态真实：雨/汗/雾气有方向有重力，摇车站立重心前移，冲刺俯身；轮胎与地面必须接触且有投影
5. 尺寸组：同一款车三个身高模特（165/178/190cm）按等效设定展示跨高与把位落差，背景留身高刻度线位（刻度后期）
6. 人脸或背景崩坏只做inpainting，车架主体加mask保护，绝不二次生成（重绘必改碳纹与辐条）

1. 参数页：主图旁留右侧版位给后期7.2kg重量、T800碳布、50mm框高等参数表，重量标注实测范围不夸大为「最轻」
2. 尺寸页：身高建议表后期按车架几何（S/M/L）核对，不生成任何医学或健康承诺
3. 色彩管理：全组sRGB打样，熔岩红与官方色卡比对
4. 合规：不出现「比赛级第一」「永不爆胎」「爬坡快30%」等无依据表述；雨战图注明封闭测试路段；不虚构环赛冠军与赞助标识
5. 放大：C组微距保留中心高分辨率支持点击看编织纹理
