This ComfyUI workflow is designed to seamlessly integrate a product image into a background scene and apply realistic relighting using advanced AI techniques. The workflow begins by loading your product and background images using the LoadImage node. Then, it utilizes the RegexReplace node to prepare the images for compositing. The core of the workflow is the ByteDanceSeedreamNode, which leverages the Seedream 4.5 model to intelligently relight the combined images, ensuring that the lighting and shadows are consistent and natural. This technique is particularly useful for creating professional-quality product images without the need for complex photo shoots or manual editing. By automating the compositing and relighting process, this workflow saves time and enhances the visual appeal of product images.
