## Description
Stop ruining your AI images by guessing at prompts. If you're tired of inconsistent results, there is a "hidden" JSON trick to gain 100% control over every element in your AI-generated visuals. Today, we’re using Google’s Gemini and the upgraded Nano Banana 2 model to show you exactly how to manipulate your image’s "DNA."

In this step-by-step tutorial, you will learn how to:
•  Extract structured JSON data from any image.
•  Modify specific elements like color and objects while maintaining perfect structural consistency.
•  Recreate photography styles using JSON
•  Replicate photography techniques (lighting, palette, composition) across multiple images.
•  Edit JSON prompts using Gemini
•  Utilize advanced brush and text tools for precise refinement.
•  Resize images to any aspect ratio.
•  Extend images with AI outpainting
•  Upscale images to 4K
•  Remove watermarks with a free AI tool

This workflow is essential for designers, AI artists, and tech enthusiasts looking to speed up their creative process by 10x.
