“Nano Banana” is the nickname for Google’s new image tools. The real name is Gemini.

There are two versions you can use:

• The Fast Model (Flash): Creates images instantly. Good for quick ideas.

• The Pro Model (Thinking): Takes about 15 seconds to “think” before it draws. It is much smarter and better at spelling and logic.

Prompt to Generate: A split screen. Left side: A stick figure drawing fast (labeled ‘Fast’). Right side: A detailed artist painting slowly (labeled ‘Pro’). Caption: Use the Pro model for the best quality.

2. How to Write a Prompt

Don’t just list words. Describe the picture like a story.

The 4-Step Recipe

Include these four things in your prompt:

1. Topic: Who is in the picture?

1. Action: What are they doing?

1. Location: Where are they?

1. Style: What does the image look like? (e.g., “Realistic photo,” “Cartoon”)

Prompt to Generate: A simple recipe card illustration listing 4 ingredients: Topic, Action, Location, Style. Caption: Follow this recipe for perfect images.

What to Avoid

• Don’t use negative words. Instead of “no blur,” say “make it sharp.”

• Don’t mix styles. Don’t say “a photo of a sketch.” Choose one or the other.

3. Examples You Can Use

Product Photos

Save money on photographers. Upload a photo of your product and tell the AI where to put it.

• Prompt: “Place this “Your Product” bottle on a marble table. Add soft morning light and flowers in the background.”

Prompt to Generate: A professional photo of a “Your Product” bottle sitting on a white marble table. Sunlight illuminates the scene. Flowers add a touch of nature. Caption: The AI can put your product in any setting.

Diagrams for Work

This AI can spell correctly, so it is great for charts and posters.

• Prompt: “Draw a diagram of a plant cell. Label the ‘Nucleus’ and ‘Wall’ clearly.”

Marketing Posters

You can create ads with text.

• Prompt: “A summer sale poster with a beach background. Big yellow text says ‘50% OFF’.”

4. How to Fix Problems

Problem: Plastic Skin

The Fix: If people look too shiny or fake, ask for texture.

• Add these words: “Natural skin texture,” “visible pores,” “not airbrushed.”

Prompt to Generate: A close-up of a face. One half is smooth plastic, the other half is realistic skin with pores. Caption: Adding “texture” makes faces look real.

Problem: Won’t Edit People

The Fix: Google blocks editing real photos of people for safety.

• Try this: Instead of “Edit this photo,” say “Create a new image that looks like this person.”

Problem: Bad Spelling

The Fix: Keep it short.

• Try this: Put the text in quotes (e.g., “Write ‘Hello’ on the sign”). It works best with short phrases, not long sentences.

5. Summary

• ✅ Use the Pro Model for quality.

• ✅ Use Full Sentences to describe the scene.

• ✅ Ask for Texture to avoid plastic skin.
