Now this is what I'm talking about. The comparison between ACES and SRGB when pushing the light/exposure/saturation is exactly what we need in Corona. No more ugly linear-esqe burnouts and colour weirdness (and conversely ultra clamped muddy grey renders to get things under control), but instead actual filmic response like Fstorm.
This should be one of the top priorities for the dev team imo as it's a fundamental part of the output/realism of the engine.
I believe the filmic response youre looking for would be covered with the 'rework tonemapping' feature request.
there are two response curves as far as I know, the digital response curve which is very close to the human eye, and the filmic response curve which is more appealing although doesn't show the image as it would to a human eye in reality, it just looks nice.
and we have linear of course in corona, which needs to be processed to emulate a response curve then graded.
what we miss of course is the photographic/human eye response curve, we're essentially getting raw data that needs processing, it doesn't have to be this way. we're at a point where we zeroed in on the issue we're all facing. response curve! in Fstorm even if you have no idea what you are doing, if all the materials are wrong IOR glossiness diffuse you name it, the image still looks more realistic than corona simply because of the response curve that affects the scene in a way that makes it look real.
you can apply your curve at least to the luminosity of the image but then again color shifts will mess up the image and fine tuning is needed to get past the CGI fakeness barrier
