Updated v4 here, with IPAdapters, upscaler, color matching and more:  https://openart.ai/workflows/risunobushi/product-photo-relight-v4---from-photo-to-advertising-preserve-details-color-upscale-and-more/gCMFAhrxCMjqc3Xr3Zsj

Huge thanks to u/Powered_JJ on Reddit, who developed a group of nodes for using the Frequency Separation technique inside of comfyUI, thus allowing for complete detail preservation after relight directly inside of comfyUI.

It's a all in one workflow, where the user can:

- either generate a product, or start from a pre-existing product photo

- segment out the product through a SAM group

- generate a new background

- blend the original product on top of the generated background

- relight through mask (either a pre-existing light mask or by masking the resulting original product + background image in the Preview Bridge node)

- keep finer details (such as text) by using a series of nodes that act as a frequency separation technique
