Observation Sketch Poster
Use the system imagegen skill and image-generation tool. This is an edit of the supplied photographs, not a brand-new unrelated illustration.
Output contract
- Treat every uploaded photo as a separate target and return one independent raster poster per photo. Never combine photos into a collage, contact sheet, diptych, or shared canvas.
- Use a 3:4 portrait composition for each output.
- Preserve an upper photographic state and a lower observational-sketch state. The transition should feel naturally composed and gently blended or stepped, never like a rigid 50:50 split.
- Keep the upper portion recognizably photographic: preserve subject identity, count, structure, pose, silhouette, spatial relationship, real texture, natural light, and original color atmosphere. Apply only restrained high-end editorial color correction. Extend sky, ground, or ambient background when necessary for the portrait ratio, but never stretch, warp, or redesign the subject.
- The lower portion must be derived from the same image, but must not be a complete tracing. Retain only the most identifying contours, gesture, direction, material cue, and narrative relationship so the source remains immediately recognizable.
- Generate text only when the image genuinely suggests a meaningful word, short phrase, sound, time cue, memory, or symbol. Keep it sparse, subordinate, and integrated into negative space; do not add fixed titles, numbering, locations, dates, logos, labels, or a menu-like information block.
Lower-half drawing language
Build the lower half as an observational pen-and-wash manuscript on an almost-white paper tone selected from the source's overall temperature and mood. The paper may be subtly warm, cool, or tinted, but must never become a conspicuous colored background.
- Use fine, loose, uneven pen lines: broken contours, searching lines, repeated corrections, occasional heavier accents, slight inaccuracies, and unfinished edges are welcome.
- Keep critical proportions, orientation, pose, and readable silhouette accurate. A few decisive long strokes or quick gestures may carry the visual emphasis; let secondary marks fade rapidly.
- Apply transparent wash sparingly in only 2–4 source-derived signature colors. Permit light overrun, water marks, grain, and uneven coverage. Environmental color should disappear quickly instead of filling the scene.
- Treat the most important contour or action as one visual motif. Organize the page through repetition, variation, pause, accent, and sudden blank space. The subject may be offset, cropped, suspended, incomplete, or extended in one direction; it need not be centered or fully shown.
- Preserve large quiet areas. The result should feel like a carefully edited private observation notebook: improvisational in individual marks, controlled in total composition, and complete because it stops at the right moment.
Composition and exclusions
Before generation, privately identify the source's hero subject or relationship, defining contour or action, 2–4 signature colors, the most useful lower-half marks, the paper temperature, and whether any text is truly warranted. Compile those decisions into a direct image-editing prompt.
The prompt should emphasize musical visual rhythm: unequal distribution, varied line intensity, strong pauses, asymmetrical placement, and deliberate cropping or suspension. Avoid average spacing, complete filling, decorative clutter, or an overly polished illustration finish.
Hard exclusions: no multi-photo canvas, no source-photo montage, no full lower-half watercolor landscape, no literal full-scene redraw, no dense crosshatching, no heavy black outlines, no vector-clean line art, no cartoon or anime styling, no 3D rendering, no glossy gradients, no generic decorative marks, no fixed information panel, no commercial poster template, and no watermark.
Review and correction
Inspect each result at full size and thumbnail size. If it looks like a filtered photo, strengthen the selective lower reconstruction and its visible pen marks. If it looks like a complete illustration, restore photographic truth and texture above. If the lower half is too busy, remove marks and recover white space. If the composition feels like a hard split, soften the transition through overlap, fading, partial continuation, or an intentional pause. If text becomes prominent or generic, remove it or reduce it to a small image-derived accent. Regenerate with one targeted correction when needed.
Return all independent images, clearly one per source photo, with no promotional copy.
