Anyways, nobody care about mapping lut.

I don't see what is the issue ?

It's free post-production tool, no one is holding gun against head of anyone. Do you provide some better one ?

I just provide additional information that would allow for better control.
To see where problems may arise, you can read my previous post.

@dubCat :
Thats a basic dslr workflow. Like every photographer do.
Your LUT (From dcp or icc) mapped to your dslr sensor, with everything that goes with it (Dynamic range, bit depth, ect...).
And this LUT cannot be used on a C-300 or D500, even H6D-100C...even less 35mm cmos...
It can be taken for a generic LUT, but Dynamic range, bit depth, ect... cannot be mapped exactly.

So your lut can be mapped to a cg render, but not cover the entire dynamic range of cg render.
Your lut cover only 2^15, minimum raw cg render (16bit) is twice the level value. So like a say before, black or white value (in some cases) will be clipped.
Data level distribution, won't match either.

Anyways, nobody care about mapping lut.

Maybe I'll release 64 sliced versions in the future, 41+ should be enough for what you want.

I don't understand ?!
You deliver a LUT that was generated from 3 random LUT Canon dslr ... There is nothing logical in it ?!
Canon LUT are created for mapping Canon sensors, like arri, red et cie...
So what do not tweak a curve and that it ?! (ed: i just plot your LUT_03).

So here we've got a LUT that not mapping the raw data ? i'm not talking about 32 bit float raw, but just for this exemple 16 bit is enough.

It's that simple.
I just want to understand the interest of mapping a LUT that does not match the RAW's digital depth. Like dslr, or camera manufacturer do.

@dubcat :

I find it strange to use LUT that is not related to the digital depth of the image rendered ?!
If I open the LUT there is only 32,768 correction line (2 ^ 15). But if you work on a 16bit image it would take 65,536 (2 ^ 16) lines of corrections ...
So why lost the half data ?

you are not actually losing anything, this is resolution of the mapping function, not the input data - even low-res mapping function can be used to transform high-res input data with no quality loss.

As an example: Corona VFB uses 32bit color format. If you change exposure, you are applying a transformation that could be expressed as 1 line LUT. But the output image does not lose any information

I meant, losing half data of bit depth of the LUT, not the raw. This LUT is just like a "film look" ?!
Is not totaly matching to the raw data (eg 16 bit or 32 bit) soulder and foot curves too.
Which causes either the floor noise will be processed, or the high values will not be processed by the curve. (And vice versa).

Sorry for not responding sooner.
However I had seen your answer, it is what i looking for.

Thank you.

Hi,

There is a solution to get Position and Normal pass AA and no-AA ?!

If a check "filter OFF" on the 3dsmax renderElement tab, i've got an undersampling Aov's (see below).


Any idea ?!

thanks

deep data remain for some future release

Got the posibility to have choice of CoordSystem "World, Object, Camera" ?

And by the way, would like to know the translate of traditional expression :
Beauty = Diffuse x(RawGI + RawLight) + spec + refract + sss + SelfIllum...

Hi,
Excellent work ! after few test, good&powerful renderer. Continue to test...:)
