I'm 99% sure everything will end up coming out overexposed, but I'm gonna go with that article on this and give it a shot!
Porta will tolerate 7 stops over with good results.
No it won’t, this is a persistent myth for some reason. Good results at one and two stops over, then you get a marked increase in graininess with further overexposure. Look up H+D Curves if it’s not obvious why.
