Re: HDR -> SDR conversion
:hat: It looks much better at handling highlights, plus the "tm" parameter is great. Noticed some differences with v1.4 again, at this point I compare against madVR but it's getting harder to tell which is supposed to be "correct" Screenshots in order: v1.4 light=250, v1.5 light=250 tm=0.90, madVR 2...

Re: HDR -> SDR conversion
My bad, I thought it was obvious, the lighting is all weird on the window side. The plain white looks like saturation was applied to it and luminance dropped completely. https://thumbs2.imgbox.com/d3/75/KxYiRRse_t.png Sample: https://mega.nz/#!sVtAnAIQ!lOOwvKGOWy-ltqhafsNLeT1GvIaI9VBHfY9LyzWQmLk Scr...

Re: HDR -> SDR tonemapping
Ideally saturation should only be adjusted for around highlights that cause these very saturated colors, as overall the default saturation is good.
I don't think anyone cares for Hable anymore

Re: HDR -> SDR tonemapping
Yes sorry, there's mostly visible blocking around vivid/deep colors.

Re: HDR -> SDR tonemapping
I'm guessing he's comparing with the SDR version (from a SDR mastered Bluray). The center of the highlight (luma around 235) is wider with default settings, so "overblown". Either that or 235 is too high? I don't know. Mobius' peak setting does help because it doesn't affect the overall brightness, ...

Re: HDR -> SDR tonemapping
In order: peak=3, HDRTools tonemap
Regarding dmcs' issue, I guess peak=2 would fix the overblown highlight. That's usually a value that works well.
I just derailed from the initial problem with the "contouring" issue, sorry for that.

Re: HDR -> SDR tonemapping
I'm not sure if it's what you mean as clipping, but on the edges going from very bright light to green it looks like squares instead of a smooth transition/gradient.
Mostly noticeable at lower light like the light=160 screenshot, the one at 500 looks good.

Re: HDR -> SDR tonemapping
Old versions of madVR used to have a similar issue, fixed a while ago though. Took a screenshot from v.0.92.14 but madshi has been working on proper colors in highlights in the last few test builds, still waiting on a final decision. There's definitely some desaturation happening, in the past you co...

Re: HDR -> SDR tonemapping
It looks good now, pretty much the same colors as HDRTools
Also where has Mobius been all this time? It's amazing the control you can have over highlights, which Hable didn't have

Re: HDR -> SDR tonemapping
You're right, there's a difference between none and mobius mostly only in highlights, mobius being much better at retaining detail and not overblowing the lighting. However the colors are still off, and increasing saturation doesn't restore the reds. I managed to get the old 1.2 version of the plugi...

Re: HDR -> SDR tonemapping
Thanks for the update :salute: There seems to be some issues with the tonemap parameters none and mobius are returning the same result, and hable is very dark in <150 luma (light param only affects high luma areas) Also the saturation looks off, the reds are unsaturated for some reason.

Re: HDR -> SDR tonemapping
I'm not sure if it's of any use (since there's not much documentation about the code), but there's this plugin which does conversion from BT2020 (and others) to BT709, as well as linear HDR -> SDR https://github.com/jpsdr/HDRTools I've been able to get good results (other than the linear lighting) w...

Re: HDR -> SDR tonemapping
I think light defaults for Gamma should be left like they are now, it all depends on the film tonemapped so it should be adjusted by the user.
Resized to 720p to take less space
default vs light=0.55

Re: HDR -> SDR tonemapping
I think white=2.5 for Hable is a bit overkill as default, a lot of highlights are overblown, it should be at least 5.
The old default of ~11 was too high

Re: HDR -> SDR tonemapping
Can the Hable parameters be changed with the new plugin? I'm not sure if I missed something in the readme or not.
