Lut to convert XYZ to RGB with DCI-primaries

[Ola Haldor voll]

I’m not sure you could beat a deal like that. £ 100 for a LUT that you potentially can earn back in no time doing grading is not a steep price if you ask me.

The alternative is to buy the software and make it yourself.

Well, would be grart to heare, how to earn 100 GBP (=120 €)in no time 🙂

I assumed that this is a very common lut, so that it would be a 5 min copy&paste job for them.
And I’am far far away from earning 120€ in 5 min 🙂

Anyway if there is no better deal I will order…

Hmm, no further reply.

So all you fsi- and dreamcolor-user have purchased at ‘Light Illusion’?
Or are you not interrested in checking the XYZ-results – maybe I miss something??

i don’t see why you want to check the XYZ on a “non XYZ” display …

For XYZ are virtual primaries, there is no XYZ-display existing.
So if you want to view XYZ-coded colors you have to convert to real primaries.
Depending on the ‘wideness’ of the real colorspace you will see a part of the XYZ-coded colors.
After grading in 709 I have converted a short to XYZ for DCI.
But as there is a gamma 2.6 and other whitepoint and lower lightness. I would like to get an idea how it will look in dci.
This should be possible with a monitor that meets dci-specification.

so you are saying that you have graded for 709 ,
than converted to XYZ (with a lut i guess ) , now you want to watch that on the same display (but setting the display to P3 color space) and you need a XYZ to 709 Lut ..

so what is the point of converting 709 to XYZ if you have than to convert it again to watch it ?

i actually thought that DCP compliant projector could accept XYZ directly …

Thanks a lot. I will have a look at it.

Yes.

Graded on a Broadcastmonitor, after finishing the client asked me to build a version for DCI.
To check the results of the conversion-lut I would like to preview it on an other monitor in p3.
Due to the different whitepoint and an lower brightness I suppose that there is perhaps more required than a mathematical conversion.

[Gabriele Turchi] “thought that DCP compliant projector could accept XYZ directly”
But then it first convert internally to its own real primaries
