The difference between a mediocre AI image and a stunning one often comes down to how well you write your prompt. Think of it as giving directions to a talented artist -- the more specific and clear you are, the better the result. Here are proven techniques that work across all AI models.
The Prompt Formula
Start with the subject, then layer in details: style, lighting, composition, and mood. A strong prompt might be: a portrait of a woman reading in a cozy library, soft golden hour lighting through tall windows, oil painting style, warm earth tones. Notice how each element adds specificity without being overwhelming.
Common Mistakes to Avoid
Avoid being too vague -- beautiful picture gives the AI nothing to work with. Don't overload with contradicting instructions. Skip negative descriptions like not dark -- instead describe what you want. And don't forget aspect ratio -- a landscape scene looks better in wide format.

The Prompt Formula
Follow this structure for consistently great results: [Subject] + [Action/Pose] + [Setting/Background] + [Style] + [Lighting] + [Camera/Composition]. Example: A samurai warrior standing on a cliff edge, cherry blossoms falling, ukiyo-e woodblock print style, dramatic side lighting, wide angle shot.
Style Keywords That Work
Different style keywords trigger different aesthetics. For photorealism, use photograph, DSLR, 35mm, Canon EOS. For illustration, try digital art, concept art, artstation. For classic art, use oil painting, Renaissance, Baroque. Our AI art styles guide has a complete list of style keywords organized by category.
Negative Prompting
While NanoBanana AI's models understand positive prompts best, you can guide results by being specific about what you want rather than what you do not want. Instead of no blur, say sharp focus, high detail. Instead of no watermark, the platform automatically generates clean images.
Advanced Techniques
For consistent character design across multiple images, describe your character in detail and reuse that description. For scenes with text, DALL-E 3 handles text rendering best -- see our model comparison for specifics. If you are generating images for marketing, include brand-relevant descriptors in your prompts.
