JRVR tonemapping bright areas

<< < (2/6) > >>

mattkhan:
There's some discussion in the jrvr thread iirc, you should post pictures showing a comparison along with your settings though then we can see what you are talking about

Sure thing...I have attached some pics below and labeled them as best as I can.. First pic demonstrating the blown out hills in the scene from 1917 which then fade in.  80 nits settings for testing, and gradually the background detail emerges in the second pic.  The same scene playing in MadVR at 80 nits, where this detail is not blown out for some reason. Note the difference in the sky detail and hills.  I also attached images of some of the settings.  Let me know if this is helpful.  I appreciate it!!

mattkhan:
good find

there's definitely a momentary brighten adaptation in the background in that scene for me with jrvr, it lasts a v short period of time (sub second) but is not present with madvr. I would expect that is related to the brighten adaptation algorithm but couldn't be sure of that. Does it last longer for you or it's similarly a brief white out and then back to normal?

I'm not sure if mine is as severe as yours or I'm just watching it in motion vs a screen cap, perhaps you can share a precise timestamp for that one?

if it is what I think it is, I don't think this is fixable by tweaking and it would be one for Hendrik to take a look at.

Hendrik:
There is always a balance between instant adaption to scene changes, and potential issues with flashing. Probably just going to accept this as is.

mattkhan:
@Hendrik can you (re)confirm what the "lively" preset is in terms of the parameters we can tweak? I suspect it's the same as the params I suggested a while back but just wanted to check
