Nano BananaTutorial: How to Use Google 2.5 Flash Image

On August 26, Google DeepMind unveiled a new image editing mode known as Google Flash, aka Nano Banana. It is already in early preview, and according to Google, it is a top-rated image editing model.

This model is used for:

Key Features of Nano Banana

• Character Consistency: Whether you're adding a hat, changing a hairstyle, or blending multiple images, Nano Banana ensures that people, pets, and objects maintain their core appearance across edits. 
• Multi-Turn Editing: Refine your images step by step—like updating a room’s color scheme, inserting furniture, or shifting details—all while preserving balance and coherence.
• Multi-Image Fusion: Blend elements from different images into seamless, realistic composites. For example, merge your photo with your pet’s or apply textures from one image onto objects in another.
• Natural-Language Prompts: Give instructions like “blur the background and add a sunflower field” or “remove the stain from the shirt,” and the AI performs targeted edits with precision.
• Accessible Across Platforms: Available to both free and paid Gemini users on mobile and web interfaces.

Prompt Engineering Guidelines for Nano Banana

• Be Hyper-Specific: Instead of "change background," use "change the background to a sunny beach with palm trees and blue ocean"
• Use Descriptive Language: "Make me look like a princess in the Ramayana, holding flowers" works better than "make me look like a princess"
• Progressive Editing: Use multi-turn conversations for complex edits:
• Context Preservation: The AI remembers previous edits, so you can refine iteratively
• Quality Enhancement: After multiple edits, use "Upscale this image" to improve quality
