I´ve been trying to fix one deleted scene from a movie and I didn´t find a way to get rid of this grey/blue halo/glow around characters. It follows character movements as well like a ghosting artifact. I tried a lot of DeHalo filters but didn´t work. I attach two screenshots with the issue marked.
Cheers¡¡
Hate to say this, but you will probably have to recomposite that such that the character is rotoscope out on a separate layer…fix the background with masking/curve adjustments and then overlay the character on top of a fixed background. It looks like a bad green screen composite where the shot was brighter than the background placed in (light bouncing off their clothes)
