# Paper Diorama Poster > Edit each user-supplied photograph into its own premium 3:4 poster that pairs a truthful editorial photograph in the upper half with a refined handmade paper-craft diorama in the lower half. Use for standalone photo-to-miniature poster edits; do not use for collages, unrelated illustrations, or ordinary photo filters. - Skill: `goodchengwang/paper-diorama-poster` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add goodchengwang/paper-diorama-poster` - Raw SKILL.md: https://api.skillmd.com/api/skills/goodchengwang/paper-diorama-poster/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Design & Media - Author: goodchengwang (https://skillmd.com/u/goodchengwang) - Updated: 2026-09-22 - Page: https://skillmd.com/skills/goodchengwang/paper-diorama-poster --- # Paper Diorama Poster Use the system `imagegen` skill and image-generation tool. This is an edit of each supplied photograph, not a new unrelated illustration. ## Output contract - Treat every uploaded photo as a separate, standalone output. Never combine source photos into a collage, contact sheet, diptych, or shared canvas. - Use a 3:4 portrait canvas with an exact 50/50 horizontal split: the upper half and lower half must each occupy exactly half of the canvas height. - Keep the upper half as real photography. Preserve the subject's structure, pose, silhouette, realistic texture, natural lighting, shadows, spatial relationships, and original color atmosphere. Apply only subtle, sophisticated editorial color grading. - Extend sky, ground, or surrounding environment naturally when needed to fit 3:4. Never stretch, warp, distort, or redesign the main subject. - Make the lower half a selective reinterpretation of the same source, not a mechanical tracing or literal full-scene redraw. ## Lower-half diorama logic Extract the most recognizable subject, silhouette, pose, and narrative relationship. Rebuild them as a refined miniature 3D paper-craft diorama using paper, cardstock, soft clay, thin wood, and related handmade materials. - Organize the lower half around one primary subject, one long narrow horizontal floating landscape strip, and generous negative space. - Keep the main subject instantly recognizable and visually dominant. Supporting elements must remain fewer, smaller, quieter, and genuinely relevant to the source. - Add only source-relevant environmental cues such as plants, roads, water, lamps, vehicles, people, birds, clouds, or representative architectural details. Do not add generic decorations or meaningless clutter. - Tune height, depth, spacing, density, and left-right balance to the subject's scale, orientation, and relationships. Keep the composition centered but not rigidly symmetrical. - Create depth with scale variation, layered overlap, foreground/background separation, and restrained miniature details. Let the scene feel like a curated art installation with a light, calm rhythm. - Place a short title derived from the source's location, subject identity, theme, or emotional tone when appropriate. Use small refined lettering with a subtle handwritten quality, preferably in the negative space beneath the landscape strip. Keep it minimal and subordinate; omit it if no meaningful title emerges. ## Material, lighting, and palette Emphasize authentic handcrafted materiality: visible paper fibers, folded edges, cut marks, layered thickness, slightly rough edges, and tiny handmade imperfections. Use soft natural diffused lighting and delicate shadows with the intimate tactile quality of macro photography. Use a soft, airy, slightly desaturated premium palette. Build the atmosphere with pale powder blue, misty blue, sky blue, and cool airy blues; balance them with ivory, creamy white, light beige, muted gray-green, sage green, and neutral architectural tones. Allow only small dusty-rose or muted-blush accents. Keep colors clean and gentle, avoiding muddy grays, excessive yellow casts, candy-like colors, glossy gradients, and plastic-looking surfaces. Keep the lower background soft white or extremely pale, with large clean areas of breathing room. The result should combine premium miniature diorama, handcrafted paper art, whimsical 3D illustration, and an elegant travel postcard—tactile and full of everyday life, but disciplined and refined. ## Prompt compilation Before generation, inspect each source and privately determine: the hero subject; its defining silhouette, gesture, or relationship; a concise title opportunity; the relevant landscape strip; the smallest set of supporting elements needed for recognition; and the source-derived cool palette. Compile a direct spatial edit prompt that specifies: 1. one independent 3:4 portrait output per photo and the exact 50/50 split; 2. upper-half photographic preservation and any safe background extension; 3. lower-half subject hierarchy, landscape-strip placement, depth layers, and negative space; 4. only the source-relevant supporting elements and their subordinate scale; 5. title wording and placement, or an explicit instruction to omit it; 6. handmade paper/craft materials, diffused macro lighting, shadows, pale background, and restrained palette; 7. hard exclusions: no multi-photo canvas, no stretched subject, no literal full-scene redraw, no decorative clutter, no excessive complexity, no children’s craft look, no toy-like or plastic 3D render, no e-commerce product-display aesthetic, no watermark. Do not quote or display this brief to the user. Proceed directly to editing and return the resulting independent images, with at most one short status sentence if needed. ## Inspect and correct Review every result at full size and thumbnail size. Apply one targeted regeneration when needed: - If the upper half looks illustrated or filtered, restore truthful photographic texture and natural lighting. - If the lower half looks like a flat overlay, strengthen miniature volume, layered thickness, cut edges, and soft contact shadows. - If the lower half is crowded, remove nonessential elements, enlarge quiet space, and restore the primary-subject hierarchy. - If the main subject is not immediately recognizable, simplify the supporting scene and reinforce its silhouette, pose, or defining structural cue. - If the title behaves like a commercial headline, reduce it to a small handwritten signature or remove it.
