Vertical slice photo poster

Pair one untouched photograph with a quiet lower study of varied vertical slices, pale source colors, and generous editorial whitespace.

Create one independent vertical 3:4 editorial poster from exactly one supplied photograph. Never combine uploads and never output a multi-photo collage.

Divide the canvas into two equal horizontal halves at the exact midpoint. The upper and lower regions must each occupy precisely 50% of the 3:4 canvas.

Use the supplied photograph directly in the upper half. Preserve the subject identity, structure, proportions, realistic photographic texture, natural light, and original color atmosphere. Only use proportional crop to fill the half. Do not use AI outpainting, repainting, stretching, warping, mirroring, or subject redesign. Apply only a restrained editorial grade.

In the lower half, analyze the source's most recognizable subject, structure lines, perspective, visual weight, and color relationships, then shrink them into a compact editorial composition. Place a small central or slightly offset arrangement of vertical photographic slices with varied widths, varied heights, staggered top or bottom edges, and source-faithful crop positions. Interleave a few pale translucent blocks or washes derived from the source colors. The lower image should clearly correspond to the upper photograph, but it must not mechanically duplicate the full photo or repeat identical fragments.

Use a warm-white or near-white paper field with large intentional negative space. Add only a few soft painted smears, pale color marks, and fine hand-drawn lines to settle the edges. Let selected slices break, fade, hover, or taper into the paper. Keep the lower half airy, asymmetrical, premium, and editorial rather than busy, filled, or barcode-like.

At the bottom or in a quiet margin, generate a short English title and one brief observational sentence from the subject, place, action, light, or mood unless an override is supplied. Use small, simple, clear typography that never becomes an advertisement, slogan, logo, signature, or dominant graphic. Return one clean poster only.

No multi-photo collage, multiple outputs, unequal split, third section, AI outpainting, repainted upper photograph, stretched or warped subject, mirrored photo, duplicated full-photo fragments, repetitive equal-width barcode slices, crowded lower half, heavy background block, muddy or oversaturated treatment, oversized title, long copy, slogan, logo, signature, watermark, UI, or unrelated decoration.
