夜校值班老师：在旧黑板上完成一张准确的停水应急流程图

这张图用于普通劳动者口述史专题扉页。场景设在课程结束后的社区夜校教室；画面定格夜校值班老师在旧黑板上完成一张准确的停水应急流程图，粉笔灰仍悬在侧光里的瞬间。色光方案采用午夜蓝、霜白、旧铜金和暗樱桃红；以一盏现场工作灯定向照明，暗部保留环境层次。使用 3:2；镜头结构为宽银幕侧向跟拍感，主体运动方向前方留足空间，只允许边缘出现轻微运动模糊。表现方式选择真实环境摄影，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，验收重点是木纹走向、连接受力、工具角度和操作姿势。与手部动作直接接触的材料必须满足液体流向、湿痕和冷凝遵循重力与温差。动作阅读顺序：动作分层：前景清楚呈现「在旧黑板上完成一张准确的停水应急流程图」，中景以「粉笔灰仍悬在侧光里」交代结果，两层之间不插入其他事件。画面必须用「夜校值班老师」「在旧黑板上完成一张准确的停水」「粉笔灰仍悬在侧光里」说清事件，地点锁定「课程结束后的社区夜校教室」。文字仅按黑板只写标题「停水处理」和三步「关阀、报修、取水」，每个字必须准确清楚处理。人物必须是原创成年人，手脚完整，透视、重力与工具重量保持一致。

The final frame serves as an opening image for an oral-history feature on everyday workers. At a community evening-school classroom after lessons, evening-school duty teacher performs this action: finishes an accurate water-outage procedure diagram on an old chalkboard while chalk dust hangs in side light. Limit illumination and color to midnight blue, frost white, aged brass gold, and dark cherry red; one practical work lamp provides directional illumination while shadow areas retain environmental depth. Organize the 3:2 image through a widescreen lateral tracking feeling with generous lead room and slight motion blur permitted only at the outer edge. 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. Action-related materials: liquid flow, wet marks, and condensation follow gravity and temperature difference. Expand only this action: Stage the action in two layers: show “finishes an accurate water-outage procedure diagram on an old chalkboard” clearly in the foreground, then use “chalk dust hangs in side light” in the middle plane as the consequence, with no unrelated event between them. Build the event from “evening-school duty teacher,” “finishes an accurate water-outage procedure diagram on an old,” and “chalk dust hangs in side light,” anchored unmistakably in “a community evening-school classroom after lessons”. Typography: the chalkboard shows only the title “停水处理” and the three steps “关阀、报修、取水,” every character accurate and clear. Also apply this exclusion: People must be original adults, with complete hands and feet and consistent perspective, gravity, and tool weight. 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.
