The 'Image Relight' workflow in ComfyUI is designed to transform the lighting of existing images using the Qwen-Image-Edit model with LoRA support. This workflow is particularly useful for photographers, graphic designers, and digital artists who want to enhance or alter the lighting conditions of their images without reshooting. Technically, the workflow involves loading an image, applying the Qwen-Image-Edit model to adjust lighting parameters, and saving the modified image. The integration of LoRA (Low-Rank Adaptation) allows for efficient fine-tuning of the model, enabling more precise and customizable lighting adjustments. This makes the workflow not only powerful but also flexible, catering to a wide range of lighting scenarios.
