How to use effectively

Nano Banana excels with natural, conversational prompts:

Key principles

• Describe the scene, don't list keywords

• Use natural language as if talking to a skilled photo editor

• Leverage multi-image inputs for fusion and reference

• Use preservation instructions: be specific about what you want changed or created (e.g., "identical to the original")

• Take advantage of world knowledge for contextual accuracy

Effective prompting patterns

For image editing

Using the provided image of [subject], please [add/remove/modify] [element] to/from the scene. Ensure the change is [description of how the change should integrate]. Keep [specific elements to preserve] exactly the same.

For image generation

A photorealistic [shot type] of [subject], [action or expression], set in [environment]. The scene is illuminated by [lighting description], creating a [mood] atmosphere. Captured with a [camera/lens details], emphasizing [key textures and details]. The image should be in a [aspect ratio] format.

For product photo

Replace [original product] with [new product] from Image 2. Match hand pose, reflections, and [material] specular highlights. Keep label readable and preserve text legibility. No stylization.

For character consistency

"Same face, hair, makeup, and earrings across all outputs. Keep [subject] identical while changing [environment/action]. Maintain facial features, expression, and clothing exactly as shown."

For photorealistic results

Include details like:

• Camera specs: "85mm portrait lens," "shallow depth of field," "f/2.8"

• Lighting: "golden hour light," "soft window light," "dramatic rim lighting"

• Composition: "close-up portrait," "wide establishing shot," "overhead view"

• Technical details: "bokeh background," "natural grain," "high contrast"

For text editing

"Change the text from '[original text]' to '[new text]'. Maintain font weight, curvature, perspective warp, and reflections. Keep brand colors identical. No other changes."

Example prompts

• Simple edits: "Remove the person in the background" or "Make this photo brighter"

• Reference image integration: "Place the man from Image 2 next to the woman in Image 1. They are seated together, sharing a laugh as they look at a tablet. Keep the ambient lighting and depth of field from Picture 1. Maintain skin tones consistent with the original scene."

• Image fusion: "Place this product in that lifestyle setting"

• Complex transformations: "Turn this into black-and-white manga style"

• Multi-step edits: "Remove everything except the woman and mic", then "make her a 3D character in an office"

• Multi-references: "Make employee badges using this design template and this photo"

• Control aspect ratio: "Create a 9:16 Instagram Story version of this ad with neon background and space at top for text."

• Product photography: "Replace the black bottle with the green 'HULK' can from Image 2. Match hand pose, reflections, and metal specular highlights. Keep label readable and preserve text legibility; no stylization."
