Nano Banana 2.5 Prompt Guide
Turn your next visual idea into a prompt you can actually use. This guide includes original examples for product images, portraits, character concepts, campaign graphics, and targeted edits, together with a practical way to compare results and improve your instructions.
Preparing for a new image model starts with knowing what you want to create. You do not need to predict every future feature to write a useful brief. You need a clear purpose, a recognizable subject, and a way to decide whether the result works.

What This Nano Banana 2.5 Prompt Guide Covers
Use this page when you have an idea but need help turning it into instructions. Perhaps you need a clean product photograph, a character for a website, or a campaign image with enough room for a headline. Each example starts from a different practical need.
The guide also explains how to review a generated image. A visually attractive result can still miss the assignment: a bottle may have the wrong proportions, a character may lose its recognizable features, or a poster may leave no space for your message.
The examples do not depend on special Nano Banana 2.5 syntax. Treat them as briefs that you can adapt to the model, image inputs, and controls actually available in your editor. Where a workflow requires an uploaded image, that requirement is stated explicitly.
Decide What a Successful Image Looks Like
Name the Intended Use
A product listing and a launch announcement may feature the same object, but they need different compositions. For a listing, the object itself may need to fill the frame. For an announcement, you may need open space for a headline, a price, and a button added later.
Before entering a prompt, finish this sentence: “This image will be used for…” Then describe the part of the image that must work for that purpose. A useful brief might say that the product should remain easy to recognize when the image is reduced to a small thumbnail.
Separate Essential Details From Optional Choices
Write down three details that would make the result unusable if they were wrong. For a product, those might be its shape, color, and label. For a character, they might be the silhouette, face, and signature accessory. These details become your review criteria.
Other decisions can stay flexible. You might accept several background materials or lighting directions as long as the product remains recognizable. Leaving those choices open gives you room to explore without losing the purpose of the image.
Choose the Final Crop Early
A composition intended for a wide website banner will not necessarily survive a narrow mobile crop. Decide which area must remain visible. When your editor offers aspect ratio settings, select the appropriate option there and use the prompt to explain how the subject should sit within the frame.
A Starting Template for Your Image Brief
Use this template to organize your first attempt:
Create a [type of image] for [intended use]. Show [main subject] with [recognizable details]. Place the subject in [setting] and arrange the frame so that [layout requirement]. Use [visual treatment]. The result should make [priority] easy to see.
Here is a completed example:
Create a website banner for a reusable bottle collection. Show one unbranded yellow bottle with a rounded shoulder and a black screw cap. Place it on a low charcoal pedestal toward the right edge of the frame. Leave the left half available for a headline added later. Use a polished studio photography treatment. The result should make the bottle silhouette easy to recognize at a small display size.
This brief gives you a testable assignment. You can judge the silhouette, product placement, and usable text area separately instead of deciding only whether you like the overall image.
Original Prompt Examples for Everyday Projects
Studio Product Photography
Use this direction for a simple product presentation where the object needs to remain the focus.
Photograph one matte yellow insulated bottle standing upright on a charcoal stone platform. The bottle has a smooth cylindrical body, rounded shoulders, and a short black screw cap. Frame the full object with space above the cap and beneath the platform. Use a large soft light to reveal the powder-coated surface, with a narrow highlight along the right edge. Keep the background dark and understated. Present the bottle without branding or decorative props.
Review the cap, base, and overall proportions. If this is a concept rather than a photograph of an actual product, label it accordingly. When you need a specific real product, begin with an appropriate product reference instead of expecting a written description to reproduce every detail.
A Lifestyle Scene for a Product
A lifestyle image should explain where the product belongs without burying it in decoration.
Create a breakfast scene featuring a single pale yellow ceramic mug on a small oak kitchen table. Place a folded linen napkin and a closed notebook beside it. Show the mug in the foreground with its handle clearly visible. A bright window sits outside the frame to the left, and the background contains a softly blurred kitchen shelf. Keep the scene calm and lived in, with believable ceramic texture and a small amount of steam above the mug.
Check that the supporting objects remain secondary. If the notebook attracts more attention than the mug, ask for a quieter notebook color or move it farther into the background. That gives your next attempt a specific visual problem to solve.
A Banana Mascot for a Website
This concept fits a friendly image-creation brand and can be adapted into onboarding illustrations.
Design a friendly banana mascot as a small three-dimensional collectible figure. Give it a curved golden-yellow body, a short green stem, dark oval eyes, and a simple smiling mouth. Show the full character standing beside a blank picture frame that reaches about half its height. Use rounded shapes, a warm ivory background, and soft studio illumination. The character should feel approachable and easy to recognize when displayed as a small website illustration.
If you have an existing logo, use it as a reference in a compatible workflow and describe which visual features matter. Check the relationship between the stem, curve, and face. A charming new character is not automatically a faithful representation of your brand mascot.
An Editorial Portrait
Use an environment that tells the viewer something about the person rather than adding unrelated scenery.
Create an editorial portrait of an adult ceramic artist seated at a pottery workbench. Frame the artist from the waist up, with both hands resting beside an unfinished bowl. Include clay marks on the apron and a few practical tools near the edge of the table. Afternoon window light enters from the left. Shelves of handmade ceramics appear softly in the background. Use natural skin texture, restrained earth tones, and a relaxed expression.
Inspect the hands, tools, and contact between the person and the workbench. If the environment becomes crowded, remove secondary objects from your next brief. Keep the details that explain the occupation and let the portrait carry the rest of the story.
A Campaign Background With Copy Space
Plan where your marketing text will go before generating the background.
Create a wide campaign background for a summer citrus drink. Arrange lemon slices, a few green leaves, and translucent ice cubes across the lower-right corner of a pale yellow surface. Use crisp morning sunlight with clean shadows. Keep the upper-left half visually quiet so a designer can add a headline and offer later. Show fresh cut surfaces and small droplets on the ice. Do not include lettering, logos, bottles, or packaging.
Test the result with a temporary headline in your design tool. Empty space that looks sufficient at full size may still be awkward after the final crop. Review the background at the actual dimensions where people will see it.
An Educational Illustration
For information-heavy visuals, make the intended relationships clear and verify the result separately.
Create a clean educational illustration comparing three stages of a bean plant: seed, young sprout, and small leafy plant. Arrange the stages from left to right in separate areas on an ivory background. Show roots below a simple soil line and the growing plant above it. Use a consistent illustration style and leave a blank area beneath each stage for labels to be added later. Keep the plant structures easy to distinguish.
Check the biological details before using the illustration for teaching. Image generation should not replace subject review. Adding labels afterward can also make it easier to control typography, translations, and accessibility across several versions of the same asset.
An Interior Design Concept
Give the room a clear purpose and identify the objects that define it.
Create an interior concept for a compact reading corner in a city apartment. Include one mustard fabric armchair, a small circular oak side table, and a slender black floor lamp. Place the arrangement beside a tall window, with books stored on a low shelf behind the chair. Show the space from an angle that makes the walking area visible. Use warm evening light and realistic fabric, wood, and painted wall textures.
Review whether the furniture fits together spatially. Look at table height, lamp placement, and the route someone would take to reach the chair. A convincing concept should communicate a usable arrangement, even when it is not a measured architectural plan.
A Short Headline Within an Image
Treat text as something to inspect closely, rather than assuming every letter will be correct.
Create a simple square poster for a neighborhood plant exchange. Use the exact headline “GROW TOGETHER” in large dark lettering across the upper half. Place three illustrated potted plants along the bottom, with distinct leaf shapes and yellow ceramic pots. Use an ivory background and a restrained green accent. Include no additional wording. Give the headline enough clear space to remain readable at a small size.
Read the output character by character. If the wording is inaccurate or difficult to edit, generate the illustration without text and set the headline in a design tool. That also gives you reliable control over font choice and spacing.
Editing Prompts for an Uploaded Image
These examples require an image-input workflow that supports the requested edit. They describe the intended change; they do not guarantee that every unrelated detail will remain identical. Compare each output with the source before accepting it.
Replace the Surroundings of a Product
Use the uploaded bottle photograph as the source. Retain the bottle silhouette, cap design, visible label, and viewing angle. Replace the surrounding scene with a charcoal studio backdrop and a dark surface beneath the bottle. Add a believable contact shadow at the base. The bottle should remain the same apparent size within the frame. Do not introduce props around it.
Review the label and outline at close range. If either changes, return to the original source rather than using the altered version as your new reference. Repeatedly editing an already inaccurate product can make it harder to recover the details that mattered initially.
Change a Material or Color
Change the blue upholstery on the chair to a warm mustard fabric. Keep the wooden frame, stitching layout, cushion shape, and position of the chair. The replacement fabric should appear under the same room lighting as the source image. Leave the other furniture and wall colors unchanged.
Check the seams and places where fabric meets wood. These boundaries are useful indicators of whether the edit has affected neighboring areas. For a real purchase decision, treat the result as a color concept rather than a guaranteed representation of the finished material.
Remove a Distracting Object
Remove the empty cardboard box beside the table on the left. Reconstruct the visible floor and the small section of wall behind it so they continue naturally from the surrounding area. Keep the table legs, nearby chair, and existing room arrangement. Do not add replacement objects in the cleared space.
Inspect the reconstructed area for repeated patterns, strange edges, and inconsistent shadows. A successful removal should fit the wider scene, not just hide the original object beneath a patch that attracts attention.
Adapt an Image for a Wider Layout
Adapt this image for a wider website composition, if the editor supports extending the canvas. Keep the existing subject at its current proportions and place it toward the right side of the final frame. Continue the simple background into the new space on the left. Leave that added area clear for a heading. Avoid stretching the original subject to fill the wider frame.
Use the editor’s actual canvas or aspect ratio controls when available. If canvas extension is unsupported, create a fresh wide composition using the source as a reference, or complete the layout in a separate design application.
Plan a Related Set of Images
A campaign often needs several images that belong together. Before generating a set, create a small visual brief that records the features you want to repeat: the product or character description, background family, lighting direction, and intended use.
For the banana mascot, the brief could specify a golden-yellow curved body, a green stem, dark oval eyes, an ivory background, and soft three-dimensional rendering. Then assign a different task to each image: holding a picture frame, presenting a finished image, or pointing toward a download symbol.
Use the same approved reference wherever the workflow permits it. Review the images together at their intended display size. Compare the character’s proportions and face, not only the overall color palette. If one illustration looks like a different character, revise that image before treating the set as finished.
Consistency should be evaluated in the outputs. A repeated description is a useful working brief, but it is not evidence that an unreleased model will preserve identity perfectly across different scenes.
Run a Simple Prompt Comparison
Choose one prompt and write down what you want to learn. For example, you might want to find which lighting direction makes the yellow bottle easiest to recognize against a dark background.
Create three versions of the brief. In the first, request broad soft illumination. In the second, request a stronger side light. In the third, request a subtle rim light. Keep the product, framing, and background instructions the same. Use the same available editor settings where practical.
Save each prompt beside its result. Record whether the bottle outline is clear, whether the cap looks plausible, and whether there is enough space for the intended headline. This is a small creative comparison, not a model benchmark, but it gives your next decision a concrete basis.
If you later try another model, reuse the brief and review criteria. Record which model produced each image. Do not relabel an existing Nano Banana 2 result as a Nano Banana 2.5 example.
Fix Common Problems in the Result
The Subject Is Too Small
Specify how much of the frame the subject should occupy and which edges must remain visible. For example: “Make the bottle occupy most of the image height, while leaving a clear margin above the cap and below the base.” Review the next result at thumbnail size.
The Background Competes With the Subject
Identify the distraction. You might ask to remove bright props behind the product, lower the contrast of the rear wall, or reduce the number of background objects. A focused adjustment makes it easier to tell whether the composition has improved.
The Image Has No Useful Space for Text
Describe a specific area that needs to stay quiet. For example: “Keep the left third free of objects and strong highlights.” Then test your actual heading in that area. The right amount of space depends on the copy and final crop.
An Edit Changes Important Product Details
Return to the original photograph and narrow the request. Review the result against a short list of essential details, including the outline, label, and cap. If the workflow cannot preserve them adequately, use a more controlled editing method for the final production asset.
The Result Looks Good but Misses the Brief
Revisit the intended use. A dramatic image may fail as a product listing, while a clean catalog image may feel too plain for a campaign. Change the composition or treatment to serve the task instead of adding decorative details without a clear purpose.
Nano Banana 2.5 Prompt Guide FAQ
Are These Verified Nano Banana 2.5 Prompts?
No. They are original sample briefs for planning image-generation and editing tasks. They are not presented as tested instructions for a released Nano Banana 2.5 model. Model-specific results should be added only when access and supported workflows can be verified.
Can I Try These Examples With Nano Banana 2?
Yes. Use the text examples as starting points in the available Nano Banana 2 editor. Editing examples require a suitable source image and the corresponding image-input workflow. Adapt any request that falls outside the controls available to you.
Do I Need to Mention Nano Banana 2.5 Inside the Prompt?
You can keep the prompt focused on the image you want. Select the actual model through the product’s available controls. Typing a different model name into the image description does not establish that the requested model is available or being used.
Are Longer Prompts Always Better?
Length alone is not a useful success criterion. Include details that you will actually check in the output. A short product brief can be sufficient for an uncomplicated scene, while a campaign layout may require more explanation of placement and intended use.
Can I Use the Same Prompt Across Different Models?
You can reuse a creative brief, but do not expect identical results or controls. Record the model and settings used, then compare the details that matter to your project. Treat differences as observations from your examples rather than proof of universal superiority.
Should I Include Text in the Generated Image?
You can request short wording when the selected workflow supports image generation, but inspect every character in the output. For exact brand typography, long passages, translations, or frequently changing offers, adding text afterward may give you more practical control.
When Will Nano Banana 2.5 Examples Be Added?
Examples can be developed once Nano Banana 2.5 is available and its actual workflows can be tested. Until then, this page provides reusable creative briefs. The available generation links lead to Nano Banana 2 or Nano Banana Pro, not an unreleased 2.5 editor.
Start With One Image Idea
Pick the example closest to your project, replace the subject details, and decide what a successful result needs to show. Try it with Nano Banana 2, inspect the output, and save the version that gives you the most useful starting point.
