Unfortunately, halos often occur with very high-contrast images and edges. Often they are very disturbing and it would be nice to make them disappear by "magic". Manual editing with Photoshop takes quite a long time, depending on the motif. Since the ML or AI supported object recognition works relatively well, it should be possible to finally do something against these stupid halos.
Therefore my suggestion:
AI/ML based anti-halo slider that can be applied as a mask to the image.
