楼顶云朵档案

为「楼顶云朵档案」设计 16:9 原创招贴，活动规模克制且非商业。画面中心呈现“半透明档案袋在屋顶封存不同云边”，物件要真的接触并产生形变，不增加第二个视觉噱头。主视觉和排版共同服从偏心竖构图，不要把文字贴在图像之外。标题使用「楼顶云朵档案」，副标题使用「为普通人的经验留一个位置」，活动信息写「临河观察台」「穿防滑鞋并带铅笔」，字形清楚。除真实比例标本、风向线和水汽外不添加装饰。材料按双色丝网印刷与矿物颜料薄层制作，纸面受压与墨色变化清楚，使用深海蓝、壳白、海藻绿与柿橙。低位工作灯作为唯一主光，接触影较硬，远端影逐渐变软，所有投影方向一致。最终图像仅含招贴本身，裁切不碰关键信息，并为「楼顶云朵档案」的活动信息留足空间；不借品牌、明星、IP、HUD、二维码或奢华展示获取注意，保持「楼顶云朵档案」的公共活动语气。

Design an original 16:9 placard titled “Rooftop Cloud Archive” for a restrained, noncommercial gathering. Center the image on translucent archive sleeves on a rooftop preserving different cloud edges. The objects physically touch and deform, with no second visual gimmick. Make image and typography share an asymmetric vertical composition; do not park text outside the artwork. Use “Rooftop Cloud Archive” as the headline, “Leave room for ordinary experience” as the secondary line, and “the riverside observation deck” plus “wear nonslip shoes and bring a pencil” as event information. Introduce no decoration beyond true-scale specimens, wind-direction lines, and moisture. Construct the print in two-color screen printing with thin mineral-pigment layers, with visible pressure and ink change, colored through deep-sea blue, shell white, seaweed green, and persimmon orange. Use a low work lamp as the only key light. Contact shadows are harder, distant shadows soften, and every projection shares one direction. Show only the placard, with essential information protected from trim. Use no brand, celebrity, IP, HUD, QR code, or luxury display shortcut. For the final rendering, let the central idea unfold through one precise material event: translucent archive sleeves on a rooftop preserving different cloud edges. Let the transition cross one focal plane so the viewer can understand it immediately at poster distance. End the image at the printed edge, with no wall, frame, clip, or presentation shadow. Final art direction: editorial poster design with a disciplined grid and material-aware composition. Use this controlled palette as the dominant visual system: #F2EBDD, #243447, #C65D48, #D6A14B; preserve believable local material colors within it. Preserve the requested text hierarchy and wording as part of the design, but do not invent extra slogans, pseudo-text, logos, 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 16:9; no variants, process sheet, split panels, mockup frame, or contact sheet.
