The Luma Image to Image node allows you to modify existing images based on text prompts using Luma AI technology, while preserving certain features and structures from the original image.

In this guide, we’ll show you how to set up an image-to-image workflow using this node.

To use the API nodes, you need to ensure that you are logged in properly and using a permitted network environment. Please refer to the API Nodes Overview section of the documentation to understand the specific requirements for using the API nodes.
