Generative Fill - Replace Background
I have original photography -studio shot of a high end bicycle. Image is now on pure white, but has not been outlined to a transparent background, just pure white. I have a separate image of a landscape background. Is it possible to use Gernative Fill to either replace the white background with the landscape image, or to drop the bicycle image onto the landscape file -without the white background. The bicycle has spoked wheels, cables, etc. and a very light grey frame. As a Retoucher, I would use various hands on techniques to outline (silo) the bicycle, but I want to see if Generative Fill can be used in this case, and in similar scenarios. This needs to be very accurate, with no ghosted areas.
