bamboo-bridge joint repairer: removes a split bamboo pin

Finished use: the key visual for a community repair initiative. At a bamboo bridge above a rain-swollen stream, bamboo-bridge joint repairer performs this action: removes a split bamboo pin, shapes a new joint, and marks its load position. Render through environmental photography preserving natural skin, worn surfaces, and atmospheric depth; focus follows the hand action while location lighting creates the background layers naturally while maintaining grain direction, joint loading, tool angle, and working posture. Organize the 3:2 image through a medium-close triangular composition whose anchors are the hands, gaze, and essential tool, with reduced background contrast. Emphasize only this surface behavior: timber and bamboo retain grain, cuts, and load compression. Limit illumination and color to bone white, graphite gray, berry red, and cool sky blue; overcast side light reveals humidity and surface relief without blowing water highlights. Action direction: Stage the action in two layers: show “removes a split bamboo pin” clearly in the foreground, then use “shapes a new joint, and marks its load position” in the middle plane as the consequence, with no unrelated event between them. The readable chain is “bamboo-bridge joint repairer” to “removes a split bamboo pin” to “shapes a new joint, and marks its load position,” all grounded in “a bamboo bridge above a rain-swollen stream”. Exclude plastic skin, floating tools, wrong contact shadows, cloned people, and false signatures. Final art direction: environmental documentary photography, natural skin and worn working surfaces. Use only this controlled palette: #39505E, #E9E3D5, #B58A42, #D85B37; preserve believable local material color inside that system. Keep one unmistakable primary subject and one readable action. The eye must enter at the action contact point, then read the consequence and finally the setting. Use disciplined negative space and avoid default perfect symmetry. Physical credibility is mandatory: correct gravity, contact shadows, tool weight, joint loading, fabric tension, liquid direction, reflections, scale, and occlusion. Human hands must be complete and anatomically plausible. Create an original visual with no resemblance to a public figure, copyrighted character, existing campaign, or living artist signature style. No visible text, letters, numerals, logos, brand marks, signatures, interface elements, labels, captions, borders, or watermarks anywhere in the image. Avoid plastic gloss, waxy skin, generic luxury-ad lighting, excessive bloom, meaningless lens flare, floating objects, duplicated limbs, clutter, random decorative icons, and synthetic AI collage artifacts. Return exactly one finished image composed for 3:2; no variants, process sheet, split panels, mockup frame, or contact sheet.

交付目标是社区修复行动专题主视觉。镜头进入雨季上涨溪流上的竹桥，只讲竹桥榫卯修复匠拆下开裂竹销，削出新榫并标明受力位置这一件事。媒介为真实环境摄影，保留自然皮肤、磨损表面与空气透视；镜头焦点紧随手部动作，背景层次由现场光线自然形成，重点控制木纹走向、连接受力、工具角度和操作姿势。镜头采用中近景三角构图，手部、眼神和关键工具构成三个视觉锚点，背景压低对比，输出 3:2。动作相关材质：木竹表面保留纹理、切口与受力压痕。光线与配色：骨白、石墨灰、莓果红和冷调天蓝；阴天侧光说明湿度与表面起伏，水面高光不过曝。动作层级：动作分层：前景清楚呈现「拆下开裂竹销」，中景以「削出新榫并标明受力位置」交代结果，两层之间不插入其他事件。看清「竹桥榫卯修复匠」「拆下开裂竹销」与「削出新榫并标明受力位置」；场所仍为「雨季上涨溪流上的竹桥」，不用摄影棚或抽象背景。可见文字：画面完全无字，不出现数字、品牌、签名或水印。排除塑料皮肤、漂浮工具、错误接触阴影、复制人群和伪签名。
