When I use “photorealism” I can use the “change bg” option and I almost completely respect the cropped image (such as a person). The “flux 1 context pro” option disappears and if I indicate, for example, “girl in the dark forest”, it usually modifies the already cropped model for me and after generating several times there is one that once again respects the model that I want to change the background. This flux option I really like the results that photorealism gives me because it helps me to correct lights and shadows and merges my model better with the backgrounds it generates.
