Nano Banana Pro Prompting Guide: The Core Prompting Principles

Google recommends that your prompts include six key elements:

1. Subject – Who or what is in the image
   
2. Composition – Framing, camera angle, and shot setup
   
3. Action – What’s happening in the scene
   
4. Location – Background or environment
   
5. Style – Aesthetic choice (photorealistic, editorial, etc.)
   
6. Editing/Constraints – Specific instructions for adjustments or limitations
   

Pro tip: Write your prompt like a mini creative brief, not just a list of keywords.

Example:

"Composite image showing [Character A] standing next to [Character B], consistent lighting from [direction], matching shadows on shared ground, unified depth of field, photorealistic style with identical color grading, seamless edges, professional photo composite quality."

How to Write Effective Nano Banana Pro Prompts

Think of Nano Banana Pro as a professional visual artist. The clearer your instructions, the better the results.

1. Use Full Natural Language

Unlike older AI tools that relied on short keyword lists, Nano Banana Pro understands full, natural language instructions. Google recommends writing prompts as if you were explaining your idea to a human designer or photographer.

This means using complete sentences, descriptive details, and clear relationships between elements.

Why it works:
A detailed prompt communicates what the image should include, how it should look, and the overall style. This makes it easier for Nano Banana Pro to generate cohesive, high-quality results.

Strong Prompt

• "A vibrant editorial close-up portrait featuring glossy pink eyeshadow, softly blended blush, diffused studio lighting, and a dreamy pastel backdrop."

  
  

Poor Prompt

• "cool makeup, pink eyeshadow, trend"

2. Add Context and Intent

Nano Banana Pro performs much better when it knows why the image is being created. Context helps the AI make smarter decisions about composition, lighting, and emphasis.

Google and the DEV Community note that intent-driven prompts generate more accurate and usable results.

Why it works:
When the AI understands the purpose—social media post, tutorial, brand campaign—it can adjust the visual style and polish the output appropriately.

Strong Prompt

• "Create an Instagram-ready beauty shot for a YouCam Makeup tutorial, highlighting dramatic contouring and sculpted cheekbones under warm golden natural light."

  
  

Poor Prompt

• "beauty portrait with contour makeup"

3. Be Specific About Camera & Lighting

Nano Banana Pro responds well to photography-style instructions, including camera angle, focal depth, lighting, and aspect ratio. Google recommends using these cues to improve realism and composition.

Why it works:
Camera and lighting details anchor the AI’s decisions, reducing randomness and producing professional-quality results.

Strong Prompt

• "A close-up beauty portrait shot with shallow depth of field (f/2.0), soft golden-hour lighting, gentle shadows on the face, and a 16:9 panoramic composition."
  

Poor Prompt

• "portrait photo with nice lighting"
  

4. Use Iterative Edits Instead of Re-Rolling

One of Nano Banana Pro’s strongest features is iterative prompting. If the first result is close but not perfect, don’t start over—refine your prompt while keeping the main instructions intact.

Why it works:
Iterative edits preserve what works and prevent inconsistencies, which is especially important for branding or multi-image series.

Strong Prompt

• "Keep the same makeup style, lighting, and composition, but slightly increase the intensity of the eyeliner and add a subtle glossy finish to the lips."

  
  

Poor Prompt

• "Try again, different style"

5. Set Clear Constraints and Priorities

Nano Banana Pro works best when it knows what must remain consistent and what can change. Setting constraints helps the AI focus on key visual elements rather than making unnecessary assumptions.

This is critical for branding, character consistency, and multi-image projects, where even small differences can break visual continuity.

Why it works:
Constraints act like guardrails. They tell the AI which elements are non-negotiable—such as identity, makeup style, and lighting—and which elements are flexible, like background or pose.

Strong Prompt

• "Maintain the same facial structure, skin tone, makeup style, and lighting across all images. Only vary the background color and head angle slightly while keeping the overall editorial aesthetic consistent."

  
  

Poor Prompt

• "Same person, different looks"

Common Mistakes to Avoid

Even experienced creators can make simple errors when prompting Nano Banana Pro. Here are the most common mistakes:

1. Vague or short prompts
   Using keywords like “cool makeup” or “pretty background” doesn’t give enough guidance.
   
2. Skipping context or purpose
   Without knowing the intended platform or style, AI outputs can feel generic.
   
3. Ignoring camera and lighting details
   Leaving out focal depth, light direction, or aspect ratio can reduce realism.
   
4. Re-rolling instead of editing
   Starting over wastes time and often results in inconsistent outputs.
   
5. No constraints on key elements
   Failing to specify what must remain the same can break continuity across multiple images.
