How to Get Great Results with Nano Banana 2
- Step 1
Leverage improved prompt accuracy with detailed descriptions
Nano Banana 2's dramatically improved prompt accuracy means your detailed descriptions translate directly into the image. Be specific about lighting, mood, angle, and style. Include terms like 'cinematic lighting', 'dramatic backlighting', or 'golden hour' to guide the model's lighting engine. The more precise your language, the closer the output matches your vision.
- Step 2
Use negative prompts to eliminate common issues
Nano Banana 2 supports negative prompts—use them to exclude blurry, low-quality, or unwanted elements. Common effective negatives include 'blurry, deformed hands, extra limbs, low quality, watermark'. For character work, add 'bad anatomy, disfigured' to the negative prompt to take advantage of the model's improved anatomy capabilities.
- Step 3
Craft cinematic hero portraits with lighting direction
Nano Banana 2 excels at hero portraits. Start with a clear subject description, specify the angle (three-quarter view, looking-up shot), then add lighting: 'rim lighting from behind', 'soft key light from left', or 'volumetric god rays'. Include a mood adjective ('epic', 'brooding', 'triumphant') and a background hint ('blurred forest', 'glowing runes') to complete the composition.
- Step 4
Create epic battle scenes with layered composition
For battle scenes, build your prompt in layers: foreground subject, midground action, and background environment. Describe the type of conflict, weapons or spells involved, and environmental conditions like 'smoke-filled ruins', 'lightning-split sky', or 'glowing magical barriers'. Nano Banana 2's improved prompt accuracy handles complex multi-element scenes with strong compositional balance.
- Step 5
Refine existing art with image-to-image
Use image-to-image mode to refine concept sketches, enhance reference images, or iterate on generations. Set denoising strength around 0.6–0.75 to preserve the core composition while letting Nano Banana 2 improve details, lighting, and anatomy. Lower strength (0.4–0.5) for subtle refinements; higher (0.8+) for dramatic style changes.
- Step 6
Balance step count and CFG for optimal results
Nano Banana 2's defaults (22 steps, CFG 4) are well-calibrated for quality and speed. Increase steps to 28–30 for highly detailed environments or complex character scenes. Lower CFG (3–3.5) for more creative freedom; increase to 5–6 to push prompt adherence harder. Avoid very high CFG values (7+) which can cause oversaturation and artifacts.
