The 'Magnific: Image Relight' workflow is designed to transform the lighting of a source image by applying the lighting conditions from a reference image. This is achieved using the Magnific model, which excels in understanding and replicating complex lighting scenarios. The workflow begins with the 'LoadImage' node, which allows you to upload both your source and reference images. The core of the process is the 'MagnificImageRelightNode', which analyzes the lighting patterns in the reference image and applies them to the source image, creating a seamlessly relit version. Finally, the 'SaveImage' node is used to export the newly relit image. This workflow is particularly useful for photographers and digital artists looking to enhance or alter the mood of their images without extensive manual editing.
