Photo Structure Blueprint Poster

Photo Structure Blueprint Poster

Use the system imagegen skill and image-generation tool. Treat every uploaded photograph as an edit source, not merely as inspiration for an unrelated scene.

Output contract

• Produce one independent raster poster for every uploaded photo. Never combine photos into a collage, contact sheet, diptych, or shared canvas.
• Use a 3:4 portrait canvas with one exact horizontal 50/50 division. The upper half is truthful photography; the lower half is a structural blueprint reconstruction derived from that same photo. Neither region may cross or obscure the other.
• Maintain clear visual correspondence between the halves while making the media change unmistakable at thumbnail size.
• Return every poster as a separate image. Keep user-facing text to one short status sentence only when necessary.

Preserve the photographic upper half

Keep the source subject recognizably photographic. Preserve identity and count, anatomy or construction, proportions, pose, silhouette, direction, spatial relationships, real materials, natural light, and the original color atmosphere.

Apply only restrained art-magazine, independent-publication, or exhibition-photography color correction. Do not redraw, vectorize, beautify, materially relight, or apply illustration texture, diagram lines, paper grain, or graphic overlays to this region.

Crop deliberately for the upper half. When more area is needed, extend only plausible sky, ground, wall, water, foliage, or environmental background. Never stretch, warp, mirror, duplicate, or redesign the subject.

Read the source before designing

For each photo, privately identify:

1. the one hero subject or inseparable subject relationship carrying recognition;
2. its defining outer contour, posture, direction, scale, and structural rhythm;
3. the internal logic that best fits the subject rather than a generic machine metaphor;
4. one or two details worth enlarging, sectioning, separating, or tracing through space;
5. the source color carrying the strongest identity and energy;
6. a short supported title plus a few useful component, state, direction, or scale labels.

Do not expose this analysis or repeat the user's design brief.

Choose subject-appropriate internal logic

The lower half must explain the source subject through a transparent, layered structural language while keeping its outer silhouette immediately legible. Interpret its interior according to what it actually is:

• objects and devices: components, shells, joints, fasteners, material layers, and functional connections;
• architecture and interiors: spatial volumes, sections, load or enclosure relationships, circulation, and construction layers;
• vehicles and transport: chassis, propulsion, suspension, load path, movement direction, and major assemblies;
• plants and natural growth: branch hierarchy, veins, root or growth direction, and layered biological geometry;
• animals and people: pose skeleton, balance, movement trajectory, clothing layers, carried objects, and abstract structural relationships—never flesh, organs, gore, or clinical dissection;
• landscapes and natural objects: strata, flow, erosion, force direction, contour, and spatial formation.

Show only the structures that clarify identity, function, action, or narrative. Do not fill the subject with arbitrary gears, circuitry, pistons, or sci-fi components.

Construct the blueprint lower half

Use the source-derived subject as the single visual core. Preserve its recognizable exterior contour, pose, direction, proportion, and relationship to any essential secondary subject. Simplify or remove incidental background detail.

Build hierarchy with a restrained combination of:

• transparent overlays and nested material layers;
• selective cutaway, section, or X-ray passages;
• one local exploded view or enlarged detail when useful;
• motion, force, growth, circulation, or connection paths;
• very fine axes, dimension lines, leaders, node numbers, small callout boxes, or miniature sectional diagrams.

Let information grow naturally from the subject. Differentiate levels through line weight, opacity, solid versus dashed strokes, density, and a few localized highlights. Keep large areas of clean negative space and a deliberate reading path. The result should feel like engineering drawing, scientific illustration, future archive, and premium editorial design combined—not like a dense interface screen.

Derive a luminous monochrome system

Extract the most distinctive and spirited color family from the upper photograph, then translate it into a clear, bright, businesslike monochrome diagram system. It may be blue, green, red, orange, purple, or neutral; never default automatically to blue.

Use:

• one very light ground;
• one principal line color;
• a small range of lighter and darker values from that same family;
• transparency, line density, and localized highlights for depth.

Keep the palette clean, rational, airy, and luminous. Avoid dirty gray casts, low-key darkness, rainbow coding, neon cyberpunk color, gradients that mimic glossy UI, and complex multicolor effects.

Integrate technical editorial typography

Derive one concise title from the subject's identity, function, state, action, or symbolic meaning. Add only a few short component names, state words, node numbers, scale marks, direction labels, or micro-notes that are supported by the image.

Attach labels precisely through leaders, rulers, arrows, detail frames, vertical setting, or edge-aligned type. Typography must participate in the diagram and retain premium magazine restraint. Keep all wording short enough to render legibly.

Do not use years, issue numbers, logos, signatures, pseudo-language, large explanatory paragraphs, generic sci-fi terminology, or invented technical facts.

Compile the image-edit prompt

Write one source-specific production prompt per input photo containing:

1. one independent 3:4 portrait output and the exact 50% photography / 50% blueprint split;
2. the upper-half preservation invariants, restrained color correction, deliberate crop, and any safe background extension;
3. the lower-half hero contour, pose, relationship, and subject-appropriate internal logic;
4. the selected transparent layers, cutaway or section, enlarged or exploded detail, and meaningful paths;
5. the placement and hierarchy of axes, dimensions, leaders, nodes, callouts, and negative space;
6. the exact source-derived monochrome family, pale ground, line hierarchy, and localized highlights;
7. the exact short title and restrained technical labels with their relational placement;
8. hard exclusions: no multi-photo layout, no altered or redrawn upper subject, no approximate split, no lower-half photo filter, no generic outline drawing, no arbitrary machine parts, no organ or flesh anatomy, no dense HUD, no neon cyberpunk, no multicolor clutter, no year, no long copy, no logo, and no watermark.

Use concrete spatial and structural language instead of relying on adjectives such as “premium,” “technical,” or “futuristic.”

Inspect and correct

Review every result at full size and thumbnail size. Verify the exact 1:1 split, truthful upper photography, immediate lower-subject recognition, plausible subject-specific structure, clear information hierarchy, source-derived single-hue palette, ample negative space, and concise readable annotation.

If the upper half looks illustrated, restore photographic texture and remove graphic treatment. If the lower half is merely an outline, add one meaningful transparent layer and one structural relation. If it resembles a machine-parts collage or sci-fi HUD, delete arbitrary internals and most labels. If the subject becomes hard to recognize, strengthen the exterior contour and pose. If the palette is dark, dirty, or multicolored, return to the source-derived light monochrome system. If text is malformed or excessive, simplify it and regenerate with one targeted correction.
