Flux Background Change Workflow
This workflow utilizes various tools such as depth, redux, fill, layermask, etc., to achieve background transformation for people or objects.
Depth processing distinguishes the subject from the background, uses redux to migrate styles and switch subject backgrounds through the uploaded background reference image, then handles edge transitions with feathered masking, and finally optimizes edge transitions with fill.
The lighting of the subject and background may not match well. Replace the uploaded background reference image with one that has similar lighting to the subject, or use my IC Light lighting control workflow.
