ComfyUI is a super powerful node-based, modular, interface for Stable Diffusion. I have a brief overview of what it is and does here. And full tutorial content coming soon on my Patreon.
In this model card I will be posting some of the custom Nodes I create. Let me know if you have any ideas, or if there's any feature you'd specifically like to see added as a Node!

Drop in your ComfyUI_windows_portable\ComfyUI\custom_nodesfolder and select the Node from the Image Processing Node list. Simple Node to pseudo HDR effect to your images. A real HDR effect using the Y channel might be possible, but requires additional libraries - looking into it.
