Nano Banana 2.1 AI 圖像模型的核心功能

探索圖像創作、參考圖像引導的編輯和海報構圖。描述你想要的效果,再透過聚焦重點的指令和需要保留的細節,逐步完善視覺方向。

自訂提示詞與海報構圖

提示詞

A low-angle, close-up photograph capturing a young woman with wavy brown hair outdoors at dusk. She is wearing a grey cropped t-shirt with a blue and white graphic text that reads '{argument name="shirt text" default="DESTINED SET 1958"}' and black denim bottoms. Her head is tilted, and she is looking directly into the camera lens. The dark blue evening sky serves as the background, with silhouetted tree branches visible at the bottom of the frame. Strong flash lighting is directed from the front, illuminating her face and highlighting strands of her hair. The composition has a grainy film photography aesthetic.

提示詞

A cinematic, high-resolution product photography shot of a square glass perfume bottle filled with amber liquid, resting on jagged black volcanic rock. The bottle features a matte black rectangular cap and gold serif text reading "FIRE" above smaller text "eau de parfum". A large, glossy black serpent is coiled tightly around the base of the bottle, its head raised to the left near the cap with a forked tongue flicking out. Wisps of white smoke curl upwards from behind the bottle against a background of glowing orange magma and dark cave walls. The lighting is dramatic and warm, emphasizing the translucency of the perfume and the texture of the snake's scales.

提示詞

Create a square 1:1 illustration. Scene: A traveling herbalist's wooden wagon parked in a wide flower-filled meadow, shelves of glass jars and bundled dried herbs hanging from the sides, a small folding table covered in potions and plants, a canvas shade stretched overhead, and butterflies drifting lazily through the warm open field. The wagon is unattended; no character is present. Style: Fantasy hand-drawn watercolor illustration style. Traditional watercolor rendering with visible pigment splashes, fluid paint diffusion, and softly blended tonal transitions. Constraints: no people, human figures, faces, silhouettes or hands; no readable text, logo, watermark, border or UI.

參考圖像編輯與背景變更

參考人像
參考人像 (提示詞)

Create a clean 16:9 premium studio product photograph for a later image-edit demonstration. Show one freestanding penguin-shaped loose-leaf tea carton centered on a warm off-white seamless background. Its construction is distinctive and easy to preserve: a tapered folding-paper body, two small side flaps suggesting wings, a neat triangular top closure, and a stable flat base. Use matte deep-navy paper with a cream front panel, a small orange beak-shaped geometric accent, and restrained silver foil details. The front label must display the exact words 'POLAR TEA' once, in large clean uppercase sans-serif lettering, with the smaller exact line 'LOOSE LEAF' beneath it. Keep both lines sharp, correctly spelled and fully readable. Constraints: exactly one package; no people; no extra text, brand logos, watermark, border or UI.

編輯後的背景
編輯後的背景 (提示詞)

Using the provided package image, create a 16:9 professional industrial-design presentation sheet for the penguin-shaped loose-leaf tea carton. Preserve the package's exact penguin silhouette, tapered folding-paper body, side flaps, triangular top closure, deep-navy and cream color blocking, orange beak accent, silver foil details, and the exact readable label 'POLAR TEA' with 'LOOSE LEAF' beneath it. Place a centered heroic 3D rendering with realistic materials. Surround it with clearly organized technical views: front, side, top, bottom, oblique perspective. Include precise pencil sketches of frame structure and crease lines. Constraints: no people; no redesign of the package; no fake logos, watermark, border or UI.

精準版面配置與文字定位

原始版面配置
原始版面配置 (提示詞)

Create a 16:9 design-review image containing one finished vertical tea poster centered on a plain light-gray presentation wall, with generous empty margins on both sides. The poster artwork features a clear glass cup of pale jasmine green tea, fresh jasmine flowers, delicate tea leaves and soft spring-green botanical shapes on a warm ivory background. Render the exact headline 'STEEP INTO SPRING' once at the top in large dark-green uppercase serif lettering. Render the exact smaller line 'JASMINE GREEN TEA' once beneath it in clean uppercase sans-serif lettering. Both lines must be correctly spelled, sharp and fully readable. Constraints: no people, human figures, faces, hands; no extra text, logos, watermark, border or UI outside the poster.

調整後的文字與構圖
調整後的文字與構圖 (提示詞)

Transform the provided 16:9 tea-poster image into a realistic metro-station lightbox advertising scene. Preserve the poster artwork, glass cup, jasmine flowers, tea leaves, botanical shapes, colors, layout and typography. Keep the exact headline 'STEEP INTO SPRING' and exact smaller line 'JASMINE GREEN TEA' unchanged, correctly spelled, fully readable and dominant. Show the vertical poster behind glossy glass in one illuminated advertising frame mounted on a clean contemporary subway-platform wall. Constraints: no sharply focused person, identifiable face or identifiable ethnicity; no extra signs; no watermark, border or UI.
