To get a truly high-quality image from Nano Banana, it's not enough to just write a few words about the scene you want. The final result largely depends on how detailed and clear your prompt is. The more precise the description, the higher the chance the model will create exactly the image you had in mind.
This article gathers the best Nano Banana prompts for a variety of tasks: from photorealistic portraits and concept art to ad banners, logos, infographics, and photo editing. We'll also cover the principles of writing effective prompts, common mistakes, and techniques that help you get better results.
What a prompt is in Nano Banana
A prompt is a text description of the image the neural network should create. It defines the scene's content, artistic style, composition, lighting, object materials, and many other details.
If the request is too short, the model fills in the missing information on its own. Sometimes this produces a good result, but more often the output differs from expectations. A detailed prompt makes generation more predictable.
For example, the request:
Red sports car
versus the description:
Red Ferrari F40 driving along a coastal highway during sunset, cinematic photography, warm golden light, realistic reflections, motion blur, 35mm lens, ultra detailed, HDR, 8K
will produce very different levels of detail.
How to write good prompts for Nano Banana
Almost any successful prompt consists of several elements.
Main subject
First, describe the main subject of the image.
For example:
- a person;
- a car;
- a robot;
- an interior;
- a cityscape;
- an animal.
The more specific the description, the easier it is for the model to understand the task.
Environment
Next, add the setting.
For example:
- a modern office;
- a Japanese street at night;
- snow-covered mountains;
- a space station;
- a tropical island;
- an ancient castle.
The environment helps shape the composition of the future image.
Artistic style
The next step is choosing a style.
Commonly used ones include:
- photorealistic;
- cinematic;
- anime;
- watercolor;
- oil painting;
- cyberpunk;
- concept art;
- Pixar style.
Style defines the overall look of the image.
Lighting
Lighting significantly affects the mood.
Popular options:
- golden hour;
- soft studio lighting;
- dramatic lighting;
- neon lighting;
- moonlight;
- overcast weather;
- sunset.
Even the same scene will look different when the lighting changes.
Shooting parameters
Nano Banana interprets common photography terms well, using them as reference points when building the image.
For example:
- 35mm lens;
- 50mm lens;
- 85mm portrait;
- macro photography;
- wide angle;
- aerial view.
Image quality
At the end, detail parameters are usually added.
For example:
- ultra detailed;
- highly detailed;
- HDR;
- realistic textures;
- volumetric lighting;
- sharp focus;
- 8K.
This approach helps produce a more predictable result compared to short prompts.
A universal formula for a good prompt
For most tasks, a simple structure works:
Subject + action + environment + style + lighting + camera parameters + detail level.
For example:
Young architect working inside a futuristic office overlooking a cyberpunk city, cinematic lighting, photorealistic, 35mm lens, realistic reflections, HDR, highly detailed.
This structure fits almost any type of image.

Advanced prompt-writing techniques
Once you've mastered the basics, you can move on to more detailed scene descriptions.
For example, instead of a short prompt like:
Beautiful forest
it's better to write:
Ancient mystical forest at sunrise, giant trees covered with moss, golden light passing through the leaves, soft fog, fantasy atmosphere, cinematic composition, realistic textures, highly detailed, 8K
A more detailed description helps the model reproduce the intended scene more accurately.
Another useful technique is combining artistic style with photographic terms.
For example:
Futuristic city skyline, concept art, cinematic lighting, 35mm lens, realistic reflections, volumetric fog, ultra detailed architecture
This approach produces a more expressive composition and more natural lighting.
Practical tips
If the image didn't turn out as expected, there's no need to rewrite the whole prompt. Often it's enough to change just one or two parameters:
- add a lighting description;
- change the image style;
- swap the camera lens;
- refine the environment;
- reduce the number of objects in the frame;
- increase the level of detail.
This approach helps you get to the result you want faster and avoid excessive regenerations.
Common prompt-writing mistakes
Even experienced users don't always get the result they want on the first try. In most cases, the issue isn't the model's capabilities but the prompt itself.
The most common mistakes:
- too short a scene description;
- missing lighting information;
- no artistic style specified;
- contradictory instructions in a single prompt;
- too many objects;
- trying to describe dozens of details at once;
- repeating words like masterpiece, best quality, or ultra realistic without a concrete description of the image.
If a generation turns out poorly, try changing just one element of the prompt — lighting, composition, or style, for example. This approach helps you quickly figure out what's actually affecting the result.
How to improve a failed generation
Sometimes an image comes out almost exactly as intended but needs a small adjustment. In these cases, there's no need to rewrite the whole prompt.
For example, if the image looks too dark, you can add:
soft natural lighting, balanced exposure, realistic shadows
If it lacks detail:
highly detailed, realistic textures, sharp focus, HDR
If the composition feels too cramped:
wide angle composition, more negative space, balanced framing
Changes like these help gradually improve the result without a complete prompt rewrite.
