What Makes NanoBanana Unique
Why choose NanoBanana (Gemini 2.5 Flash Image)? Here are the core strengths that make it a powerful tool for creators:
Character Consistency
Keep facial features, style, and identity intact even through edits or across multiple images.
Multi-Image Fusion
Merge multiple input images into one seamless visual: mix object + scene + reference shots.
Style Transfer & Visual Template Adherence
Apply artistic styles (realistic, cartoon, retro, painterly etc.), maintain brand or visual theme.
Precise Local Editing via Natural Language
Want to change background, adjust lighting, remove or add elements, correct pose? All via descriptive text.
High Quality Output & Fast Feedback Loop
Rich details, sharp textures, realistic lighting; iterate quickly for refinement.
How to write better Nano Banana prompts—from simple to advanced
Use these tips to get sharper, more expressive images, keep character consistency, and fully exploit the model’s abilities.
Start with a Clear Vision
Before writing the prompt, imagine what you want: type of subject (figure / portrait / scene), mood, style, lighting, color palette. Then put those details in your prompt. Don’t leave too much vague (‘make it nice’)—instead say “golden hour lighting”, “soft shadows”, “warm tones” etc. More detail = better output.
Use Complete Descriptive Sentences, Not Just Lists of Keywords
Instead of keywords like “portrait, warrior, dramatic lighting”, try full sentence prompts: “A dramatic portrait of a warrior in ornate armor, with warm ambient golden lighting and a moody castle backdrop.” This helps Nano Banana understand context and nuance. Guides and articles on Gemini’s prompting tips echo this.
Include Reference or Multiple Inputs When Possible
When you have reference images (e.g. a pose you like, an accessory, a lighting style), upload them or mention them in the prompt. For multi-image fusion or style transfer prompts, referencing multiple images helps preserve style, consistency, and compositional harmony.
Specify What Should Remain Unchanged
If you want character consistency, specify what must stay the same: face, hairstyle, outfit, proportions. If editing a photo, mention elements to preserve: “keep skin tone same”, “keep facial features same”, “keep background perspective”. This prevents visual drift between edits.
Iterate & Refine in Multiple Turns
Don’t try to put everything in a single prompt. Start with a base prompt, see what output you get, then refine: maybe adjust lighting, maybe change background, maybe tweak style. These multi-turn refinements lead to much better final images. Nano Banana is built to handle that workflow.
Use Negative Instructions / Constraints Where Needed
Sometimes what you don’t want is just as important: “no extra figures”, “avoid blurriness”, “no text overlay”, “exclude harsh shadows”, etc. Negative prompts or constraints help the model avoid common pitfalls.
Balance Style with Realism
If your goal is realism (for product shots, portraits), include details like lighting, lens, texture fidelity, reflections. If your goal is stylized (cartoon, painterly, chibi etc.), be explicit about style and exaggeration. But even stylized images look better when some realism anchors are specified (e.g. proper shading, consistent lighting).
Experiment with Style Transfer & Composition
Use prompts that ask for mixing styles or transferring styles: e.g. “take color palette from this artwork”, “blend architectural reference with fantasy scene”, “combine two poses into one balanced composition”. Nano Banana supports blending images and styles with more fidelity than many competing models.

What is a “Nano Banana Prompt”
A Nano Banana Prompt is a text instruction crafted to guide Gemini 2.5 Flash Image (aka Nano Banana) to generate or edit images. It describes the subject (e.g. figure, portrait, product), style (realistic, cartoon, sculpted), lighting, background, camera/lens details, and optionally what must remain unchanged (character consistency). Effective Nano Banana prompts help produce outputs that match your vision, minimize drift, and reduce editing corrections.
How can I keep character consistency when using Nano Banana?
Specify exactly which features must stay the same: same face, hairstyle, expression, outfit, proportions.Use reference image(s) if possible, or upload multiple inputs. Use multi-turn refinement: once you generate an image, refine via follow-up prompt (“same character but different pose / different background”).Avoid ambiguous or conflicting style directives that force the model to override identity.
How does multi-image fusion work, and when should I use it?
Multi-image fusion means feeding more than one image or reference into the prompt (e.g. a pose image + a style image + a background image) so Nano Banana can merge their features. Use it when you need: combining a stylistic reference, matching lighting or environment, or preserving elements from different photos. This helps you get more control over composition and style coherence.
What are negative prompts / constraints, and how do I write them?
Negative prompts are parts of your prompt (or separate instructions) that tell the model what not to include (e.g. “no extra people”, “avoid harsh shadows”, “no text overlay”, “exclude background clutter”). When writing them: be specific about what you don’t want; place them clearly—often after the positive description. Constraints help reduce unwanted artifacts or misinterpretations by the model.
Why is my generated image blurry / background messy / style inconsistent?
Prompt too vague—add more detail (lighting, texture, camera, background). Missing reference images or examples. Conflicting style or visual instructions in the prompt (e.g. “realistic” + “cartoonish” + “fantasy”). Overloading the prompt with too many attributes; leads to model being uncertain. Try shorter, clearer prompts; iterate: generate → adjust prompt → regenerate.
How many times should I iterate, and what changes are most effective?
Iteration is key. Recommended: start with a base prompt, see what comes out, then do maybe 2-4 refinements focusing on one variable at a time (pose, lighting, style, background). Changes that often lead to big improvements: adjusting lighting & camera lens details; refining style adjectives; specifying identity maintenance (same character); removing unwanted elements via constraints.
