How do you create professional images with Nano Banana?

The artificial generative intelligence has evolved extremely in the years 2024-2025 and the last wave of innovation is now brought by Google by launching Nano-Banana, the engine behind the Flash Gemini 2.5 image. We were curious to test how it behaves in terms of images of this new model in terms of creating and modifying images and if it manages to transform simple text descriptions into complex and high quality visions.

For graphic designers, product or UX/IU, this tool is not only a novelty, but wants to be a real partner in creative work. Is it able to accelerate work flows, with satisfactory results at professional level? We will see together, during this tutorial that invites you to try the skills of the platform of Gemini Flash images 2.5 in the generation of marketing images, advertising, user interface design and more.

Unlike the previous models, Nano-Banana excels through the consistency with which it maintains the identity of a subject in different iterations and changes. You can place the same character in different contexts, have a product from various corners or develop an identity of coherent brand. This ability to «understand» and keep the key elements of an image, combined with an intuitive editing based on suggestions, opens a world of creative possibilities.

What exactly do you need to start?

The good news is that access to Nano-Banana’s skills is surprisingly simple and largely free. Here’s what you need to use:

• A Google account: this is essential to access the ecosystem of the Ai Google tool.
• Access to Google to Studio: the main platform in which it is possible to work directly with Nano-Banana. It is an intuitive web interface, similar to that of LLMS based on written responses, in which text instructions can be inserted and loading reference images. The use of experimental is free.

For developers and advanced users, dwarfs can be integrated into their applications through the Gemini bees (paid prices paid here). Allows the automation of processes and the generation of images using various programming languages ​​(Python, Javascript, Go) or through requests for rest, offering greater flexibility.

Nano-Banana tutorial: how various types of images of flash images 2.5 are obtained

We explore, step by step, as you can use nano-banks to obtain professional results in various scenarios.

1. Photos generation: an IT specialist at work in a coworking hub

Generic stock images can often seem impersonal. With Nano-Banana, we can create a specific scene, full of authenticity, to meet our requests.

Example of prompt:

We use a descriptive formulation (richer in detail, the better).

Create a high resolution photo, in the cinematographic style, of a young IT specialist, focused at work on a high -end laptop. It is located in a modern and bright coworking space, with elements of industrial design (apparent bricks, exposed pipes) and lush internal plants. Natural light enters through a large window, creating a thin «rim light» effect on its outline. In the background, other professionals can be seen in the bokeh, collaborating discreetly. The atmosphere is of calm concentration. Use a brightly bright color palette with technological blue accents. The perspective comes from the level of the shoulder, on the side, creating a feeling of involvement in the scene.

Result:

2. Edging photos

Now that we have the basic image, we can adjust it finely using the modification prompt. We load the previously generated image (necessary for each step) and continue with precise instructions.

Color adjustment

Request:

«On the image provided, regulates the white balance to make the scene even warmer, underlining the golden tones of the West that penetrate the window.

Result:

Adding a new article

Request:

«Add a cup of white coffee on the table, to the right of the laptop. Make sure that the reflections and shadows correspond to the existing lighting. The cup should be small (espresso style).»

Result:

Adding text

Request:

«Integrate the text» umpteenth without fear «on the brick wall in the background. Use a modern brown, applied as a vinyl sticker, with a slight consistency to imitate the surface of the wall.»

Result:

In the part of the addition and modification of the text in the image, Nano-Banana did not manage excellent. A succession of instructions was required to correctly write the text offered and the result is sub -sharing from the point of view of stylizing the text to integrate correctly into the image.

3.

The flash image of Google Gemini 2.5 is also useful in the area of ​​graphic design of the product. To exemplify this area, we imagine that a new company for offices writing, called registration for, needs a logo and visual identity elements.

Request:

Create a minimalist and elegant logo for a premium pens called «Inscribbebe pens». The logo must abstract to combine the shape of a tip of the pen with the letter «I». Use a flat design, carrier, a color: a deep business blue (#003366). It generates a variant of the logo on a white background and a negative variant (white on a blue background). It presents the logo on a simulated business card, with a clean and modern design.

Result:

• Main logo (corporate blue on white background):

• Logo simulation on a business card:

(Once again, you can see the deficiencies of the current model in the clean line of the text inside the image. Although it can «read» the words included in the view correctly, the appearance of their reproduction is still desired).

4. User interface generation for a food delivery application

For UX/AI designers, Nano-Banana can quickly generate applications screens, accelerating the «conception» phase.

Request:

It generates a clean and modern design for the main screen of a mobile application for office food, called «OfficeBites». The interface must be intuitive, using a card -based system for neighboring restaurants. Each card must view a food image, the restaurant name, evaluation and estimated delivery time. Use an energizing color palette with orange as the main accent (#FF6B00). It includes a prominent search bar in the upper part and a lower navigation bar with icons for home, controls, profile and basket. The design must respect the principles of the design of the material, be airy and easy to read.

Result:

5. Generation of Wireframe for an IT recruitment site

Before the user interface, the Wireframe arrives. Nano-Banana can help to outline the basic structure of a web page.

Request:

Create a «low physidality» wireframe for the main page of the website for an IT recruitment agency. The structure must be clear and logical. From top to bottom, it includes the following sections: header of the logo and navigation, a «hero» section with a main title and a «invitation to action» button, a search section of filters, a list of works «in the foreground» presented in the form of cards, a «Why work with us» section with 3-4 key advantages and a useful connection. Use only shades of gray, placeholders (Lorem Ipsum) and simple geometric shapes to represent images and buttons.

Result:

Tips and tricks for an effective suggestion

The quality of the results depends directly on the quality of the instructions. Here are some suggestions to become a «quick engineer» in the best possible way:

• Iterate and perfection: The first result is rarely perfect. Consider it a starting point. Analyze what works and what does not, then regulates the prompt for the next iteration. It is preferable to start each time with a new chat, in which you load the previous version of your image, which you want to improve not to use the same wire, since the model will be able to degrade quickly and will give you identical images, despite the different instructions, consuming from the tokens.
• Be extremely descriptive: Don’t be afraid to use a rich language. Adjectives, metaphors and literary knowledge can transform a banal prompt into an exceptional. Specifies the style (e.g. «Photojournalistic», «Moody», «Flat»), the lighting («diffuse light», «contra-jour», «bokeh»), composition («respecting the rule of third parties», «great depth of the field») and the emotion you want to convey.
• Provides a reference visual: One of the most powerful functions of Nano-Banking is the ability to work with entry images. Do you want to edit a photo or apply a particular style? Upload a reference image together with the prompt.
• Specifies the constraints: Tell the model not only what to do but also what Not Do. For example: «It keeps the physiognomy of the character intact», «uses the colors of the brand specified exclusively».

The nano-banks are also evident, especially in the area of ​​integration of the text in the image, the errors are inherent in a model based on the stable diffusion that turns. In conclusion, when using the design of nano-banks, it is worth considering that the text will be necessary to be modified/added separately, at least in this phase of the development of the model.

Our conclusion? Used correctly, Nano-Banana is not only a generator of images, but a catalyst for creativity. Mastering the art of writing effective instructions, the designers and content creators can overcome traditional limits, can explore ideas at an unprecedented speed and can create increasingly complex and refined visions. Experiment, ivi and let your imagination fly!

This video offers an excellent visual introduction in creating suggestions to obtain high quality images, covering the basic principles that are directly applicable in the use of nano-banks. All we have to do is wish very increase to create it!
