Hi,
I saw this topic in the past and now I tried to change the camera raw mode back to 2010 from the current 2012 method.
https://forum.corona-renderer.com/index.php/topic,6186.msg42365.html#msg42365
My problem is that the image turns black as soon as I change this mode.
I wanted to try it because I want to work with the original image not with the one that camera raw automatically equalizes.
I saved a 32bit exr but no luck.
Any ideas?
Thank you,

So when you do that, and look at sliders, is there anything odd ? Are they at default ?
-
Hey, thanks for the reply.
The sliders are moved most of them to the left side maximum value.
In this case I need to find the "right" values again by eye ?
I can send a printscreen from home.
cheers

They should all be 'zero'-ed.
-
Thank you, will try at home.

Its works fine now with setting 0 to all settings by hand.
The "dark effect" when switching process modes has gone.
Looks like it was a bug I cant redo after restarting the machine.
Thanks,

That's PhotoshopCC with all the weird stuff it occasionally does :- )
But I am glad it worked, I noticed the behavior is pretty random, but what I think it does is [ It will try to "auto" adjust histogram, except it doesn't know linear is that much more wider than usual raw from camera so it can skew it bit too harschly, then when you switch to 2010, it will try to convert those previous settings and come up with something even weirder, forcing you to reset).
Anyway, I suggest updating to latest CC patch there is, seems like it added some features I didn't notice before.
Anyway x2: I stopped using fully linear to camera raw workflow, since I tonemap using Filmic in VFB+, I just follow with clamped 16bit file into CameraRaw. I still have enough range to work with as long as I had the exposure roughly correct.
This is slightly faster, more consistent workflow when you work across many images that need to look the same-ish. Doing bespoke tonemapping from linear in post is always bit different across range of different images.
-
I will give that patch a try :)
In terms of filmic tonemapping in vfb what do you mean?
-
Tonemapping=Highlight compression (but more)
VFB+ has filmic tonemapping, Corona Framebuffer has Reinhard. Reinhard is ugly :- ) --> Desaturated, bleak. Filmic keeps better contrast and saturation. So it saves me bit of work.
-
In this term 1 is linear and above it is reinhard in Corona. (Same as vray just reversed)
By VFB you mean VrayFrameBuffer right?
As I understand Reinhard is basically a bridge between linear and exponential colormapping.
But using the highlight/burn slider in VFB is not the same as using reinhards burn option in the colormapping tab?
