Photography naive flat illustration poster

Please turn every photo I upload into an individual high-end design poster, not a multi-image collage; each photo should be output separately. The overall composition adopts a 3:4 vertical format, with the top and bottom sections strictly 1:1 in height, each taking up 50% of the frame.

The upper half preserves the original photo, maintaining the subject structure, realistic texture, natural light and shadow, and the original color atmosphere, with only slight high-end photographic color grading to give it the texture of an art magazine, independent publication, or exhibition photography. To fit the aspect ratio, the environmental background can be naturally extended, but the subject must not be stretched, distorted, or changed.

The lower half extracts the most recognizable subject, outline, posture, and narrative relationship from the photo, reconstructing it into a relaxed, naive Korean-style flat editorial illustration. Retain the general layout, object relationships, and core actions of the original image, but remove realistic light and shadow, perspective, and material details. Generalize the subject into rounded, simple, slightly exaggerated geometric shapes, using rough, shaky, partially broken black hand-drawn outlines paired with flat solid color fills, so the image remains instantly recognizable but not overly realistic.

The composition maintains one clear visual center, with other objects as foils, establishing a light rhythm through size differences, misalignment, occlusion, slight cropping, and incomplete symmetry. The background uses large areas of bright solid colors and white space to support the subject, retaining left/right or partial complete color blocks as breathing space; do not pile up complex scenes, making the image look like a carefully designed children's picture book or an independent editorial illustration, rather than a cartoonized photo.

The color scheme extracts the most vital and recognizable colors from the photo above and transforms them into high-brightness, high-purity, limited-quantity flat color blocks; bright blue, red, yellow, green, white, and other color relationships with childlike tension can be used, but do not mechanically apply fixed color palettes. The background and the subject form a sharp contrast in area, avoiding gradients, shadows, gray/dirty colors, complex color mixing, and a plastic feel.

The text also adopts a naive yet design-oriented editorial logic. Extract a short English title from the subject, action, mood, or story of the photo, and pair it with a small number of extremely small short sentences, object words, location words, numbers, or playful annotations. The main title can use a font that feels slightly handwritten, uneven in thickness, or slightly tilted, while the small text remains clear and restrained; the text can be arranged along the subject's outline, color block edges, white space areas, or the image axis, and can also feature slight rotation, misalignment, splitting, and interlacing, making the text feel like a part of the illustration itself rather than typography pasted on later.

The overall presentation is a visual temperament of real photography × naive flat illustration × relaxed editorial design, which is bright, childlike, intimate, playful, relaxed, and design-oriented. Whether the subject is a person, animal, plant, building, object, vehicle, food, or natural scene, a clear visual echo should be maintained between the original photo's identity and the illustration below, avoiding cheap cartoons, complex depictions, 3D textures, a commercial sticker feel, and templated children's illustrations.
