GPT Image 2.0 Prompt - Affiche photo et crayon pastel

Create a separate, high-end editorial poster from each photo I upload. Do not combine multiple photos into a collage; output one individual poster per photo. Use a 3:4 portrait format, divided into two sections with a strict 1:1 height ratio, each occupying exactly 50% of the canvas. Upper half: Preserve the original photograph, maintaining the subject’s identity, structure, pose, realistic texture, natural lighting and shadows, and original color atmosphere. Apply only subtle, refined color grading to evoke an art magazine, independent publication, or exhibition image. If necessary, naturally extend the surrounding background to fit the format, but never stretch, distort, or alter the subject. Lower half: First identify the photograph’s most memorable core theme, relationships between subjects, structural flow, emotional tone, and visual metaphors, then reinterpret them as a pastel crayon doodle illustration on subtly textured vintage-style paper. Do not copy the photograph object by object or redraw everything it contains. Retain only the silhouettes, poses, directions, and visual memory cues that best represent the original. Through simplification, omission, slight exaggeration, and recomposition, make the connection to the photograph above immediately recognizable. Render the main subject with coarse, grainy chalk or crayon outlines. Lines should be slightly thick, loose, and dry, with powdery particles, intermittent fading, subtle wobble, and edges that do not always close. Stroke ends should be naturally blunt and rounded. Add only a few pastel patches, simple grids, stripes, dots, or casual scribbles within the subject, using minimal information to suggest its structure. Avoid realistic volume and fully rendered details. Surrounding elements must use the same line language as the main subject, further reduced to doodle symbols recognizable in one or just a few strokes. Stars, flowers, plants, objects, environmental cues, or abstract symbols should be simple, childlike, open, and imperfectly closed, relying primarily on single-line contours with very little fill. Do not turn them into polished icons, stickers, or standalone miniature illustrations. Maintain a relationship between small, stamp-like motifs and generous negative space. Position elements freely according to the subject’s direction, proportions, and visual center of gravity: off-center, close to an edge, floating, or partially cropped. The main subject and a very small number of doodle symbols should form a loose but clearly related visual group, while the rest of the space remains intentionally empty. Negative space is a primary compositional element. Use the interplay of emptiness and presence, clustering and dispersal, scale contrast, and asymmetry to create breathing room, distance, and pauses. When in doubt, draw less rather than fill the space. The background must be extremely pale, bright, clean paper, such as cream white, ivory white, pale off-white, faint apricot white, very light gray-white, or a near-white paper tone thoughtfully matched to the photograph’s overall color temperature. Retain only the faintest paper fibers and grain. It must not look brown, overly yellow, gray, or aged. The background must be distinctly lighter than the subject’s outlines and color patches, ensuring that every crayon contour, small symbol, and piece of text remains clearly visible rather than blending into the paper. Extract 2–4 of the photograph’s most lively, approachable colors that best capture its spirit, and reinterpret them as bright, soft pastel crayon colors. These may naturally become peach pink, apricot orange, creamy yellow, mint, sky blue, or pale lilac. For the main outlines, favor coral pink, soft blue, teal, warm orange, lilac, or deeper cream tones that remain clearly distinguishable from the background. Repeat these colors only sparingly in the smaller elements to create visual echoes. Maintain the contrast of a pale background + clearly visible colored lines + a few soft color patches. The overall feeling should be cheerful, soothing, relaxed, and rooted in everyday life. Avoid muddy grays, dirty browns, gloomy muted palettes, low contrast, fluorescent colors, and a cheap candy-colored look. Introduce text sparingly, in any language. Draw short phrases or fragments freely from the subject, action, emotion, memory, or metaphor. Use a lightweight, airy typewriter-style font with slightly uneven letter spacing and subtle imperfections reminiscent of old mechanical printing. Choose a clearly legible yet gentle gray-brown, soft black, deep blue-gray, or a darker color that echoes the subject, ensuring sufficient readability against the pale paper. Let the text sit naturally within the negative space, interspersed with the subject and doodles. Do not impose a fixed headline template. The final result should combine an extremely pale paper surface, coarse crayon outlines, sparse pastel fills, minimal doodle symbols, small-scale subjects, and abundant artistic negative space into a refined, soothing visual composition. The priority is to make the subject and small elements stand out clearly against the pale paper while retaining a relaxed, innocent, gentle spirit and a mature editorial sense of composition. Avoid dark kraft paper, dark brown backgrounds, low-contrast lines, subjects that blend into the background, fine precise outlines, realistic redrawings, complex miniature icons, densely filled backgrounds, smooth vector graphics, a 3D appearance, and a commercial template aesthetic.
