For using Nano Banana, especially with Google Gemini, a suggested effective prompt to create a 3D figurine from a photo is: "Create a 1/7 scale commercialized figurine of the characters in the picture, in a realistic style, in a real environment. The figurine is placed on a computer desk. The figurine has a round transparent acrylic base, with no text on the base. The content on the computer screen is a 3D modeling process of this figurine. Next to the computer screen is a toy packaging box, designed in a style reminiscent of high-quality collectible figures, printed with original artwork. The packaging features two-dimensional flat illustrations." This prompt is from Google's official Twitter and widely used to turn photos into collectible figurine images with Nano Banana. You upload a photo and use this prompt for the best result. Additionally, there are creative variations to prompt Nano Banana for different themed results like retro style, anime heroes, plush toys, cyberpunk avatars, and more, depending on the desired effect. If you want specific examples of prompts or creative ideas, I can provide those as well based on the style you want to achieve with Nano Banana.
