乡镇水泵机械师：拆开泥沙堵塞的泵盖

在泥墙围合的乡镇泵房，乡镇水泵机械师正完成拆开泥沙堵塞的泵盖，让围观学生看见叶轮重新转动。按可发布标准完成普通劳动者口述史专题扉页。以近乎正交的俯拍画面，物件按真实工作顺序散开，中心留出一个未完成动作组织 3:2 画面。色光方案采用炭黑、旧纸米色、氧化铜绿和低亮朱红；使用现场自然光，主体接触处对比最高，远景不过度虚化。用真实环境摄影，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完成画面，并保持机械连接、磨损位置、工具咬合和操作手势。动作相关材质：金属磨损集中在握持、转轴和接触边缘；土石陶表面保留颗粒、缺口和局部磨亮处。画面只展开这一动作：动作分层：前景清楚呈现「拆开泥沙堵塞的泵盖」，中景以「让围观学生看见叶轮重新转动」交代结果，两层之间不插入其他事件。看清「乡镇水泵机械师」「拆开泥沙堵塞的泵盖」与「让围观学生看见叶轮重新转动」；场所仍为「泥墙围合的乡镇泵房」，不用摄影棚或抽象背景。文字规则：画面完全无字，不出现数字、品牌、签名或水印。同时排除塑料皮肤、漂浮工具、错误接触阴影、复制人群和伪签名。

The subject is township water-pump mechanic, located in a township pump house enclosed by earthen walls, performing this action: opens a silt-blocked pump cover so watching students can see the impeller turn again. The deliverable is an opening image for an oral-history feature on everyday workers. Frame the scene with a near-orthographic overhead view with objects spread in authentic working order and one unfinished action at the center and deliver it in 3:2. Treat the location light and color as charcoal, aged-paper beige, oxidized copper green, and low-luminance vermilion; use available natural light, with highest contrast at the action contact and no excessive background blur. The medium is environmental photography preserving natural skin, worn surfaces, and atmospheric depth; focus follows the hand action while location lighting creates the background layers naturally, with precise control of mechanical connections, wear placement, tool engagement, and operating gesture. Emphasize only this surface behavior: metal wear stays on grips, pivots, and contact edges; earth, stone, and ceramic retain grain, chips, and locally polished wear. Action reading order: Keep the full action “opens a silt-blocked pump cover so watching students can see the impeller turn again” in one continuous plane, with its contact point and result both visible. Clearly show “township water-pump mechanic,” “opens a silt-blocked pump cover so watching students can,” and “opens a silt-blocked pump cover so watching students can” together; keep “a township pump house enclosed by earthen walls” as the real workplace, not a studio backdrop. Handle text only as follows: place no text, numerals, brands, signatures, or watermarks anywhere. Necessary exclusions: 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 this controlled palette as the dominant visual system: #39505E, #E9E3D5, #B58A42, #D85B37; preserve believable local material colors within it. Keep any text absent or minimal unless the source brief explicitly requires it; never add logos, signatures, or watermarks. Keep one unmistakable primary subject or information route and one readable visual action. Use disciplined negative space and avoid default perfect symmetry. Physical credibility is mandatory: correct gravity, contact shadows, material thickness, tool weight, joint loading, fabric tension, liquid direction, reflections, scale, and occlusion. Create an original visual with no resemblance to a public figure, copyrighted character, existing campaign, or living artist signature style. No unrelated decorative icons, floating objects, duplicated limbs, plastic gloss, waxy skin, synthetic collage artifacts, or AI watermarks. Return exactly one finished image composed for 3:2; no variants, process sheet, split panels, mockup frame, or contact sheet.
