[Max] General Discussion / Re: Tonemapping - Plz Halp

I think people are making the comparison because Fstorm has the best tonemapping algorithm out of all common rendering engines at the moment.
The thing is, as Juraj pointed out, we're not even sure the "Fstorm look" can be attributed to tone mapping only. So further investigations need to be conducted before making such a claim.
Maybe not attributed solely to tonemapping, but I would hazard a guess it's at least 50% of the reason. Please look at the highlights and roll-off to extreme black in the examples posted earlier by lolec - that is one aspect that is definitely down to tone mapping. Colour behaviour differences could be due to the internal colour space/custom matrix, I agree.
I would urge anyone who has doubts about the highlight/black crush issue to test it for themselves in 1:1 comparisons as Fstorm is fully functional (with watermarks). You will not get the same level of pop/photographic contrast in Corona (without external post processing), without sacrificing either blacks or highlights - I would almost liken this to differing dynamic ranges of cameras as an IRL analogy.
