school weather-instrument calibrator: compares two thermometers and writes their deviation on a waterproof board

Use a 4:5 frame with a near-symmetrical center structure disrupted by one offset tool, with straight verticals and material detail retained along the lower edge. The final frame serves as a cover for a local field-observation journal. The central event is school weather-instrument calibrator at a school rooftop weather corner before autumn rain, where the subject compares two thermometers and writes their deviation on a waterproof board. Present the scene through environmental photography preserving natural skin, worn surfaces, and atmospheric depth; focus follows the hand action while location lighting creates the background layers naturally, ensuring mechanical connections, wear placement, tool engagement, and operating gesture across subject and setting. Action-related materials: liquid flow, wet marks, and condensation follow gravity and temperature difference; paper and sheet material show folds, humidity curl, and real thickness. Treat the location light and color as charcoal, aged-paper beige, oxidized copper green, and low-luminance vermilion; overcast side light reveals humidity and surface relief without blowing water highlights. Action direction: Keep the full action “compares two thermometers and writes their deviation on a waterproof board” in one continuous plane, with its contact point and result both visible. Let “school weather-instrument calibrator” lead from “compares two thermometers and writes their deviation on a” to “compares two thermometers and writes their deviation on a”; the surroundings explain only “a school rooftop weather corner before autumn rain”. Typography follows place no text, numerals, brands, signatures, or watermarks anywhere. Avoid luxury-ad lighting, meaningless lens flare, excessive blur, garbled signs, and branded packaging. 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 4:5; no variants, process sheet, split panels, mockup frame, or contact sheet.

比例定为 4:5，视线通过中心近对称结构被一件偏置工具打破，垂直线端正，画面下缘保留材质细节抵达手部与工作物件的接触处。交付目标是地方田野观察季刊封面。主体为校园气象仪校准员，位于秋雨前的学校屋顶气象角，正在比较两支温度计，把偏差写在防水记录板上。画面语言为真实环境摄影，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，重点是机械连接、磨损位置、工具咬合和操作手势。核心物件质感按液体流向、湿痕和冷凝遵循重力与温差；纸张和薄片呈现折痕、湿度卷边与真实厚度处理。色光方案采用炭黑、旧纸米色、氧化铜绿和低亮朱红；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「比较两支温度计」，中景以「把偏差写在防水记录板上」交代结果，两层之间不插入其他事件。让「校园气象仪校准员」的「比较两支温度计」直接导向「把偏差写在防水记录板上」；背景只解释「秋雨前的学校屋顶气象角」。可见文字：画面完全无字，不出现数字、品牌、签名或水印。避免奢侈广告光效、无意义镜头光斑、过度虚化、乱码招牌和品牌包装。
