老树来信

为「老树来信」设计 3:4 原创招贴，活动规模克制且非商业。唯一记忆点锁定为“老树年轮像信封逐层打开”，任何次级元素都不得改变它的阅读方向。版式定为偏心竖构图；观者先看到物件变化，再读标题和参与信息，服务于「老树来信」的单一视觉命题。海报只保留四组文字：「老树来信」「慢一点，细节才会出现」「临河观察台」「穿防滑鞋并带铅笔」，标题仅允许一处边缘遮挡。场景只补真实比例标本、风向线和水汽，不产生第二中心。双色丝网印刷与矿物颜料薄层需要呈现正面、切边与弯折差异，色彩采用苔绿、骨白、灰紫与酸黄。单束投影白光建立画面体积，接缝附近保留最清楚的落影，背景保持安静。保持至少 5% 安全边，标题和地点不可贴边，并为「老树来信」的活动信息留足空间。不要加入相框、手持样机、Logo、名人脸、地标拼盘或 3D 发光字。

Design an original 3:4 placard titled “Letters from Old Trees” for a restrained, noncommercial gathering. Keep the growth rings of an old tree opening one by one like nested envelopes as the one memorable idea and prevent supporting elements from changing its reading direction. Set an asymmetric vertical composition. The viewer encounters the object change before the headline and participation details. Keep only four copy groups: “Letters from Old Trees,” “Slow down and the details will appear,” “the riverside observation deck,” and “wear nonslip shoes and bring a pencil.” The hero may cover one stroke edge only. Add only true-scale specimens, wind-direction lines, and moisture. Let two-color screen printing with thin mineral-pigment layers distinguish face, cut edge, and bend, using moss green, bone white, gray violet, and acid yellow. Build volume with a single projected beam of white light, keeping the clearest shadow near the seam and the background quiet. Protect at least five percent around the sheet. Do not add frames, handheld mockups, logos, famous faces, landmark collages, or glowing 3D text. For the final rendering, use one carefully engineered physical illusion for the hero: the growth rings of an old tree opening one by one like nested envelopes. Show enough thickness at the cut edge to establish the material, while the background remains flat and quiet. Keep the title’s baseline stable even where the hero approaches the letterforms. 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 3:4; no variants, process sheet, split panels, mockup frame, or contact sheet.
