This is the first of three alternative workflows from my video here:  https://youtu.be/BuSsw8Nv1N4

The video provides a full walkthrough.

You can find the other workflows here:

- relight from background:  https://openart.ai/workflows/UPKc0ak0YJibwbDff85i

- product shots relight from mask as light source:  https://openart.ai/workflows/kdypWGlBPE7DZkqHALVi

This first workflow is a very basic reorg of Kijai's own workflow for educational purposes, not much has changed.
