Affiche de style guidebook compagnon géométrique

Transform any real photo into a "geometric companion manual style" top-bottom comparison redrawn poster. Composition/framing: Strictly split into top and bottom sections. The upper ~45% of the image is a high-fidelity real photograph of the input photo, and the lower ~55% is a geometric manual-style redraw of the same subject. The horizontal boundary is clear but natural. Avoid side-by-side layouts, nine-grid arrangements, or multi-image collages. In the lower section, change the subject's scale and information density - do not mechanically trace the original composition of the photo. Style/medium: Paper specification card, travel observation page, restrained geometric collage, and hand-printed diagram. Break the subject in the photo into a few flat geometric planes, black contour lines of varying thickness, and a limited palette of 2-4 color blocks. Preserve the subject's identity, quantity, action direction, and most critical structure. Use arrows, dashed lines, numbered dots, local magnified frames, short labels, and simple structural lines to explain visible features, creating an explanatory relationship like "how to observe / how to identify." Labels must point to real visible parts or spatial relationships of the subject - do not add objects that do not exist in the photo. Scene/backdrop: The lower section uses a warm off-white paper background with slight paper fiber texture, uneven printing, and low-contrast grain. Colors are extracted and compressed from the input photo - do not default to a fixed blue-sea or dog template. Leave breathing space between the subject and the annotation frames. Text: Include only 1 short English title, 1 material/observation field, and 1 very brief caption. Text should look like labels printed on a paper card. Avoid long paragraphs, fake Chinese, URLs, QR codes, brand names, and watermarks. If the photo subject changes, the title and fields must be replaced according to the facts of the photo. Constraints: Preserve the subject's identity, quantity, pose, action direction, key structure, lighting direction, and main spatial relationships in the real photo. The upper section must not be drawn as an illustration, must not replace the subject, and must not blur or reconstruct the photo. The lower section must still clearly correspond to the same subject as the upper section at a glance, and clearly demonstrate geometric decomposition, arrow annotations, and the manual-page mechanism. Do not include "original/AI image" corner labels. Avoid: Color grading only, grain only, ordinary cartoon filters, realistic photos filling the lower section, meaningless decorative stickers, fixed dog/beach elements, overly complex engineering drawings, dense hard-to-read small text, extra people, and irrelevant landmarks.
