Cartel de medio tono con ventana de sombra

Turn the input photo into a 3:4 vertical poster titled "original photo + shadow window halftone overprint redraw". The upper 42%–50% keeps the original photo unredrawn, preserving subject count, identity, pose, action direction, architecture/terrain structure, viewpoint, lighting, and key colors, with only light editorial color grading; the middle uses a restrained warm paper-color boundary, without adding original or AI image corner marks. The lower half extracts an off-center large-scale shadow main form from the photo: people retain accurate silhouettes and actions, animals retain poses, architecture and landscapes distill skyline or main structures, food and objects distill outer contours and placement relationships. The shadow is composed of deep charcoal black, smoke ochre, or the darkest color in the photo using coarse halftone dots, toner particles, dry brush edges, partial 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. Windows may be offset, intersect, or partially cross the shadow edge, but must not form a nine-grid or regular grid. The lower half uses warm ivory, old rice white, or light gray paper surface, showing pulp fibers, stains, creases, wear, and old print ink absorption marks. Windows use low-saturation spot colors extracted from the original image, showing slight overprint misregistration, transparent color overlap, and halftone grain. Keep 25%–40% white 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.
