folk-instrument tuner: tightens a loose peg and asks an elder musician to confirm pitch with one sustained note

The deliverable is an opening image for an oral-history feature on everyday workers. Enter a folk-music room before rehearsal and show only folk-instrument tuner as the subject tightens a loose peg and asks an elder musician to confirm pitch with one sustained note. Use 3:2; guide the eye through a near-orthographic overhead view with objects spread in authentic working order and one unfinished action at the center toward the contact between hands and working objects. Use environmental photography preserving natural skin, worn surfaces, and atmospheric depth; focus follows the hand action while location lighting creates the background layers naturally; the clearest technical requirement is credible work posture, hand contact, material realism, and directional light. Use this lighting and palette: concrete gray, algae green, raincoat yellow, and natural skin tones; use available natural light, with highest contrast at the action contact and no excessive background blur. Action-related materials: hand contact, tool weight, and garment tension must be credible. Arrange the action layers as follows: Keep the full action “tightens a loose peg and asks an elder musician to confirm pitch with one sustained note” in one continuous plane, with its contact point and result both visible. Clearly show “folk-instrument tuner,” “tightens a loose peg and asks an elder musician,” and “tightens a loose peg and asks an elder musician” together; keep “a folk-music room before rehearsal” as the real workplace, not a studio backdrop. Visible text: place no text, numerals, brands, signatures, or watermarks anywhere. Final check: Do not show real trademarks, public figures, posed expressions, malformed fingers, or watermarks. 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.

请把画面制作成普通劳动者口述史专题扉页。画面中心事件：民间乐器调律师在排练前安静的民乐社团室旋紧松动弦轴，让年长乐手以长音确认音高。构图按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执行，成片比例 3:2。采用真实环境摄影，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；可信的工作姿态、手部接触、真实材质和定向光线必须清楚可信。光线与配色：水泥灰、藻绿、雨衣黄和自然肤色；使用现场自然光，主体接触处对比最高，远景不过度虚化。与手部动作直接接触的材料必须满足手部接触、工具重量和衣物受力必须可信。镜头动作说明：动作分层：前景清楚呈现「旋紧松动弦轴」，中景以「让年长乐手以长音确认音高」交代结果，两层之间不插入其他事件。看清「民间乐器调律师」「旋紧松动弦轴」与「让年长乐手以长音确认音高」；场所仍为「排练前安静的民乐社团室」，不用摄影棚或抽象背景。画面文字按画面完全无字，不出现数字、品牌、签名或水印执行。不出现真实商标、公众人物、摆拍表情、错误手指或水印。
