The Five Essential Components of the Prompt Formula

For consistently excellent results, a high-quality Nano Banana prompt must read like a director's brief containing five distinct, mandatory elements.

1. Subject Specificity The Core of the Image

The Subject is the main focus of your image. Ambiguity here guarantees a mediocre output. You must be extremely detailed.

• Detailing Identity: When generating people or characters, specify key attributes like age emotion and distinctive clothing or accessories. Nano Banana is known for its ability to maintain character consistency across multiple generations and edits, but it needs a strong initial definition.

  • Weak Example: "A cat"

  • Strong Example: "A fluffy calico cat wearing a small wizard's hat with an intrigued expression"

• Action Verbs: Always combine the subject with a strong Action verb that defines the motion or pose, making the scene dynamic.

  • Static: "A woman standing"

  • Dynamic: "A woman mid-stride in a trench coat looking over her shoulder"

2. Environment and Setting The Context Builder

The Environment provides the necessary context and atmosphere. Nano Banana leverages its world knowledge to fill in logical background details, but you need to set the scene.

• Atmosphere and Specificity: Go beyond simple locations. Define the mood and the density of the surroundings.

  • Simple: "A cafe"

  • Specific: "A futuristic Mars cafe with minimalist chrome furniture and red dust on the windows"

• Object Placement: If objects are crucial, describe their relation to the subject and the scene. This is vital for product packshots or advertising visuals.

Composition and Style Advanced Aesthetic Control

The true leap from amateur to professional AI art involves controlling the composition and stylistic aesthetics. These two elements dictate how the viewer experiences your image.

3. Compositional Control Cinematic Viewpoints

The Composition refers to the viewpoint and framing, dictating the relationship between the viewer and the subject. Use cinematic terminology to guide the AI's virtual camera.

• Camera Angles: Explicitly request the desired angle to achieve specific emotional effects or perspectives.

  • Close-up: Ideal for emphasizing emotion or intricate detail (e.g., "Extreme close-up of a golden wristwatch").

  • Low Angle Shot: Makes the subject appear imposing and authoritative (e.g., "Shot from a low angle looking up at a towering figure").

  • Aerial View: Provides a sense of scale and environment (e.g., "Bird's eye view of a winding mountain road").

• Framing: Specify the general boundary and what should be included.

4. Style and Medium Defining the Artistic Direction

The Style component tells Nano Banana the desired medium and aesthetic. This is how you transform a photorealistic concept into a unique artistic piece (e.g., an oil painting or a digital illustration).

• Art Mediums: Specify the desired technique (e.g., watercolor sketch oil painting ink drawing).

• Genre and Era: Anchor the image in a specific genre or time period to ensure consistent mood and detail.

  • Examples: "Cyberpunk film noir style," "1990s product photography," "Baroque painting."

• High-Resolution Quality: Always include terms that emphasize quality and detail (e.g., 4K HD photorealistic stunning portrait).

Lighting and Iteration The Final Layers of Realism

Even the most perfect composition will fail without masterful Lighting and the willingness to Iterate the result. These two steps separate successful creators from those who settle for the first output.

5. Lighting and Color Grade Setting the Mood

Lighting establishes the mood and depth of the image, simulating the effects of professional photography studios.

• Define Light Source and Quality: Specify both the source and the quality of the light. Avoid generic terms like "good lighting."

  • Examples: "Golden hour lighting streaming from the left," "Harsh overhead fluorescent lights," "Soft volumetric fog with rim lighting."

• Color Palette: Use color terms to define the emotional tone (color grading).

  • Examples: "Muted earthy tones," "Vivid saturated colors," "Duotone gradient."

Iterative Refinement and Editing Workflow

Nano Banana’s conversational editing flow is its hidden strength. You don't have to restart after each generation.

• Start Broad Refine Narrow: Begin with the five-part formula to define the core image. Then, use follow-up prompts to refine specific details.

  • Example:

    1. Initial Prompt (5-part formula)

    2. Follow-up: "Change the subject's outfit to a crimson velvet dress."

    3. Follow-up: "Make the light source harsher and remove the coffee table."

• Targeted Editing: When editing existing images, use specific action verbs: Add Change Make Remove Replace. This targeted approach maintains the character consistency and overall composition while transforming a small element, saving significant time.
