Thanks for the replies.
You are right, all totally valid points.
I will correct these mistakes and will add links. Very sorry for that. Didn't want to take advantage of anybody, but just wanted to help others out. I honestly couldn't remember where I got the log lut from. I couldn't find it anymore in the web. Are you alright with having it in the pack? I will take it out of you wish. If you can give me a link to the original source, I'll gladly add that.
Honestly sorry if I made anybody feel aggravated!

ok, it took me some days to find the time to correct stuff. I added links to this thread and info where I got the LUTs from and made a note about linear space in the description of the video.
Thanks @piotrus3333 for all the valuable infos on the forums and for letting me re-distribute your empty LUT and the idea.
@burnin I am not sure what to actually call the linear workflow if not talking about the workflow itself but the theory. Actually a lot of people are calling it linear space or linear RGB and everything that differs from it is Gamma correction and so on. It is some kind of space obviously but not a color space...if you can enlight me on the proper naming conventions, I would be grateful.
@dubcat if you are not ok with me republishing your LUTs, please tell me and I will take them down.

You've been told this several times already, but i'll repeat it again - unless you got author's explicit permission, it's not ok to distribute his stuff. Leaving a message on the forum and assuming that silence means agreement, it's not ok either. If you'd look at dubcat's forum profile, you should see that he wasn't logged in for 15 months, it's very likely that he has no idea about you or your request. If you're a decent person, take down those scripts now, then try to contact the author personally and explain him the situation.

What ever happened to Dubcat, by the way?

alright, I get your point and again: I dont want to aggrevate anybody. Since I am working on more LUTs, I swapped Kim Amlands LUTs with some of mine that come close to what he created and left a thank you note to him, as his workflow really inspired me.
thanks for being my Jiminy Cricket ;)

Hi, wondering if you can help. I'm trying to match my frame buffer setting in After Effects, working on an EXR sequence (16bit), but the LUT (yours I beleieve, has a different effect to in the VFB. Does it need to be applied in a specific gamma curve/colour space?

Thanks.

I remember you did a thread on virtual colour checkers.
How would that work with ACES Emulation?
Would you apply aces settings and your LUT and then use the output in lightroom to calibrate?
Colour management is all very new to me but its infinitely fascinating to get into the process of making sure my work output is accurate.

Hey!

I would capture a color checker passport at your current light intensity. Generate a camera profile. If your profile has a contrast curve, open it in 3DLUTCreator and remove it. This should give you a calibrated color and linear camera profile.
When you have a calibrated profile. The only thing you should care about is linear values. When it comes to real world albedos, we talk in linear %. If I tell you the brightest common paint is 94%, you should be able to input that value into "Value" in Corona Picker. But that is not how Corona Picker is working right now. So you have to convert 94% to sRGB. If you are thinking, why the hell do we have to gamma correct a linear value only to get a linear value, ask the Corona devs, it blows my mind every day. 94% is 97.2% sRGB, so this is the max real world scanned common paint value.

Another problem we have with the current Corona Picker is that the darkest common paint is "Jet Black" and it's 14,14,16 sRGB. Try to input these values into Corona Picker. You end up with 0,0,24 sRGB. This is a common problem when we try to sample real world values for products, the sRGB values might jump 10 sRGB. I'm using Vrays color map to fix this, because it let me adjust values separately with float values.

edit:

I haven't had much time to complete the last few guides on my site. But I want to share paint values with you guys as soon as possible, so I have remove all the unfinished stuff from the site.
I've only had time to add the 2019 Color Chart paints to the page, but have about 1 gazillion paints ready.
If you have a paint value, and are wondering how it would look with LRV and - IOR. Just post the values here, and I'll add them to the page when I get time.

How do you generate your profile?
Ive tried lightroom but it wont open exr and colour passport wont run on non raw formats.
3DLUT creator gives some really horrible results with the passport.

Is there any way you could give a slightly more in depth explanation of using it?
In terms of VFB setup, export format, and process to generate your DNT/LUT?

I still really want to know the correct workflow for this...

Does anybody know what happened to Dubcat? He hasn’t been here for years. His website is also offline :-/
