ComfyUI: Imposing Consistent Light (IC-Light Workflow Tutorial)

The video focuses on implementing IC-Light in Comfy UI, specifically for product photography. IC-Light is based on SD1.5, and we use a reference background and a product/object photo to regenerate the background and re-light the object. Images are generated in SDXL resolution, then upscaled by 4x. A number of unique techniques are used to transfer details to the final generation and even on the 4 K upscaled images.
