Application Guide

Realistic style

To achieve realistic images, use photographic terminology. Mention angles, lens types, and fine details to achieve a realistic effect.

Example Prompt Structure:

The generated image demonstrates the model’s exceptional ability to capture photorealistic details and cinematic atmosphere. The lighting falls naturally across the subject’s face, the bokeh is smooth and pleasing, and even small textures—such as skin pores and hair strands—are rendered with convincing sharpness. The subtle glass reflection adds depth, showcasing how the model excels at combining composition, lens simulation, and fine details to create an image indistinguishable from a professional DSLR photograph.

Design Style

To achieve professional and visually striking logos, focus on clean geometry, balanced typography, and versatile color palettes. Mention applications such as business cards, signage, and digital platforms to ensure adaptability. Fine details like embossing, metallic finishes, or minimal gradients can enhance realism and brand presence.

Example Prompt Structure:

The result highlights the model’s strength in premium brand presentation and professional mockups, making it ideal for client proposals or portfolio showcases.

Anime Style

To create an anime-inspired look, focus on youthful character designs, school uniforms, and rich emotional expressions. Use soft lighting, muted or vibrant colors, and clean lines to emphasize innocence and charm. Incorporating scenes like classrooms, cherry blossoms, or city streets can enhance the lived-in atmosphere.

Example Prompt Structure:

The generated image captures the charm of anime JK style with soft colors, delicate lines, and a light romantic mood, perfect for slice-of-life scenes.

Editing an image

1.Adding elements

You can add new items to the picture while keeping the original picture without feeling offended.

Adding sunglasses to the dog demonstrates the model’s semantic understanding of the image. It identifies the dog and its eyes, then naturally overlays the sunglasses in the correct position.

2.Style transfer

Provide an image and ask the model to recreate its content in a different artistic style.

Example Prompt Structure:

Transforming the dog into Monet’s style shows the model’s ability to perform style transfer, preserving the subject while reimagining it with artistic expression.

3.Combining multiple images

Use multiple images as backgrounds to create new composite scenes - perfect for product mockups and creative collages.

Combining the robe with the dog demonstrates the model’s ability to understand and merge elements from different images. It recognizes the robe’s shape and the dog’s body structure, then blends them seamlessly to create a visually coherent and realistic composition.

4. Figurine Realistic Style

If you want to try the recently popular figurine style, I suggest you use the following prompt words.

Example Prompt Structure:

This image highlights Nano Banana’s strength in merging realism with anime-inspired elements. The figurine’s fine details—such as clothing folds, paint texture, and the clear acrylic base—are rendered with convincing accuracy. The computer screen showing the 3D modeling process, together with the packaging box, creates a cohesive narrative from design to product. The result makes the figurine appear truly tangible while demonstrating the model’s ability to integrate multiple elements seamlessly. In addition, it shows strong image understanding: Nano Banana can extend the base image by expanding content naturally, maintaining proper proportions and consistent style throughout.

Best Practices with Nano Banana

To maximize Nano Banana’s strengths and elevate your generations from good to outstanding, apply these professional strategies in your workflow.

Be Hyper-Specific

Nano Banana thrives on detailed prompts. Instead of just saying “anime girl,” describe: “a Japanese high school girl in a navy blue sailor uniform with a red ribbon, standing under falling cherry blossoms, soft pastel colors and delicate line art.” The more precision, the more control over the result.

Provide Context and Intent

Clarify the purpose of your image. For example, “Illustrate a JK girl for a spring romance manga cover” will yield a more polished result than simply “draw a JK girl.” Context informs Nano Banana’s rendering choices and ensures stylistic consistency.

Iterate and Refine

Don’t expect perfection on the first try. Use Nano Banana’s responsiveness to tweak details. Follow up with prompts like: “Keep the same setting, but make the cherry blossoms denser,” or “Adjust the expression to be more cheerful.” Small iterations lead to professional-level refinement.

Use Step-by-Step Instructions

For complex anime or illustration scenes, build prompts layer by layer. Example: “First, create a classroom background with desks and sunlight from the window. Then, add a JK girl by the window. Finally, include floating dust motes for realism.” This method helps Nano Banana compose balanced, story-rich visuals.

Apply Semantic Negatives

Instead of saying “no background clutter,” phrase it positively: “a clean, minimal classroom with only a few desks and sunlight beams.” This helps Nano Banana focus on what should appear, rather than struggling with prohibitions.

Control the Camera

Nano Banana responds strongly to cinematic and illustrative framing. Use terms like “low-angle perspective,” “close-up portrait,” “wide establishing shot,” or even “dynamic manga panel composition” to guide how the subject is drawn and how dramatic the result feels.

Prompt word language

For best performance, use the following languages: EN, es-MX, ja-JP, zh-CN, hi-IN.
