Nano Banana 2 Lite Prompt - Grille de neuf portraits du même personnage

GRID STRUCTURE & OUTPUT CONSTRAINTS Create exactly ONE composite image containing exactly 9 panels arranged in a strict 3-column × 3-row grid. Exactly 3 columns and exactly 3 rows. Exactly 9 individual image panels in total. Every panel must have a portrait aspect ratio of exactly 2:3. The overall composite image must have an aspect ratio of 2:3. All 9 panels must be equal in size, aligned perfectly, with straight, clean grid boundaries. No extra panels, no additional rows or columns, no inset images, no duplicated panels, and no irregular collage layouts. CHARACTER CONSISTENCY Show the exact same character in all 9 panels. Preserve consistent facial identity, facial features, hairstyle, hair color, clothing, body proportions, and overall appearance. CAMERA ANGLES & POSES Each panel shows the same character from a different camera angle or with a different natural pose. Randomize the poses across the 9 panels while maintaining a consistent scene, background, lighting, color palette, and photographic style. PANEL INDEPENDENCE Each of the 9 panels must be a separate, complete portrait photograph. Each panel occupies exactly one cell of the 3×3 grid. Do not subdivide any panel. FINAL VALIDATION Before finalizing the image, verify that the layout contains exactly 3 columns × 3 rows = 9 panels, with no extra cells. The grid count and panel geometry are strict requirements, not suggestions.
