Transform the input photo into a 3:4 vertical "original photo + shadow window halftone overprint redraw" poster. The top approximately 42%–50% retains the original photo without redrawing, preserving the number of subjects, identity, pose, direction of action, architectural/terrain structure, perspective, lighting, and key colors, with only slight publication-grade color grading; use a restrained warm paper-color boundary in the middle, without adding original image or AI image corner marks. The bottom extracts a large-scale offset shadow main form from the photo: people retain accurate silhouettes and actions, animals retain poses, buildings and landscapes distill skylines or main structures, and food and objects distill outer contours and placement relationships. The shadow is composed of deep charcoal black, smoky ochre, or the darkest color in the photo, using coarse halftone dots, toner particles, dry brush edges, localized reverse white, and slight horizontal ink-bleed drag marks; it must not be a smooth vector black block. Overlay 2–5 rectangular observation windows at different scales around the shadow, each window only magnifying traceable real details from the input photo, such as hands, eaves, leaves, roads, water surfaces, animal eyes, food textures, or object details. The windows may be offset, overlapping, or partially crossing the shadow edge, but must not form a nine-grid or regular grid. The bottom uses warm ivory, aged off-white, or light gray paper surface, showing pulp fibers, stains, creases, wear, and old print ink-absorption marks. The windows use low-saturation spot colors extracted from the original image, showing slight overprint misregistration, transparent color overlays, and halftone grain. Retain 25%–40% negative space, and add a main title, HALFTONE STUDY, and one observation sentence of no more than 8 English words. Do not use fluorescent neon, flat two-color fills, logos, QR codes, watermarks, or garbled text.
