Prompt by @Hamburgerai

Turn the input photo into a vertical 3:4 top-bottom comparison transformation poster without watermarks. The upper half, approximately 45%, retains the original photo's complete composition, subject, action, perspective, and real light; the lower half is a hand-drawn red-line environmental sketch of the same framing. The lower half converts the buildings, streets, plants, landforms, objects, transportation, or animal environment in the photo into brick-red to ochre-red monochromatic lines made with thick markers/crayons on warm white blotting paper. The lines should have variations in pen pressure, breaks, retracing, cross-hatching, dryness, and a small amount of ink bleeding, retaining key contours and spatial relationships while removing irrelevant details and leaving broad continuous paper white. Select only one subject from the original image with the most narrative role as a real photo anchor—a person, animal, vehicle, food, or object—and retain its real texture, color, material, posture, and natural shadows in the lower half, letting it make contact with the hand-drawn ground or environment, as if stepping out from the red-line scene. The number, identity, action, scale, and position of the anchor must be consistent with the upper half. Do not turn the subject into a cartoon, do not add fantasy characters, fictional landmarks, fake text, brands, watermarks, original image or AI image tags, and do not apply full-image filters or smooth vector strokes.

About this prompt

The described artwork is a 3:4 vertical poster that juxtaposes real‑photo realism with a hand‑drawn red‑line sketch beneath. The top 45% reproduces the original photo’s composition, lighting, and perspective, while the lower half turns the surrounding environment into thick, monochrome red lines, letting only one focal object—kept realistic—bridge the two realms. The contrast is engineered through a warm white paper background that preserves high quality detail on the anchor, with the red‑lined environment providing a rough, sketchy textural counterpoint. By using varying pen pressure, breaks, and cross‑hatching in the red linework, depth is suggested without compromising the central subject’s natural shadows and texture. To adapt this for another image, identify a single narrative anchor in your photo and retain it exactly in the lower half. Keep the red‑line environment consistent in scale and perspective, but feel free to experiment with different hues (e.g., blue‑or‑green lines) if the tone of the original photo calls for it. The key is to preserve the anchor’s realism while the surrounding hand‑drawn world remains stylized.
