섀도우 윈도우 하프톤 포스터

Turn the input photo into a 3:4 vertical poster of "original photo + shadow-window halftone overprint redraw". Keep the top 42%-50% as the untouched original photo, preserving subject count, identity, pose, action direction, building/terrain structure, viewpoint, lighting, and key colors, with only light editorial color grading; add a restrained warm paper-color border in the middle, without adding any corner marks of the original or AI image. In the lower half, extract one off-center large-scale shadow main shape from the photo: keep accurate silhouette and action for people, pose for animals, skyline or main structure for architecture and landscapes, and outer contour and arrangement for food and objects. The shadow shape should be made of deep charcoal, smoky ochre, or the darkest color in the photo, rendered with coarse halftone dots, toner grains, dry-brush edges, selective reverse white, and slight horizontal ink-bleed smear; it must not be a smooth vector black block. Overlay 2-5 rectangular observation windows at different scales around the shadow; each window only magnifies a traceable real detail from the input photo, such as hands, eaves, leaves, roads, water surfaces, animal eyes, food texture, 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, aged off-white, or light gray paper, showing pulp fibers, stains, creases, wear, and old-print ink-bleed marks. Windows use low-saturation spot colors extracted from the original image, showing slight misregistration, transparent color overlap, and halftone grain. Keep 25%-40% white space, and include a main title, HALFTONE STUDY, and one observation sentence of no more than 8 English words. Avoid neon fluorescent, flat two-color painting, logos, QR codes, watermarks, or garbled text.
