LUT don't works

Recommended Posts

HI Raff

 

We are already aware of an issue with exported LUTs, it seems to be swapping or inverting the red and blue channels. I've added your information to our report. Hopefully we can get this sorted soon

 

Cheers

Thanks!  :)

 

But I think is not only a reversal of channels.

By varying the changes (even with posterization), the LUT imported was always the same.

I have a problem with exporting LUTs in that when exported and then reapplied to the same image it is nothing like the original adjustmentsI exported. Is this the same problem that was reported almost a year ago?

Hello,

Exported LUTs don't work for me too, either with Affinity Photo or in an other software. 

Doesn't the issue has to be fixed in the 1.6 version ? I'm on 1.6.2.97. 

 

Few questions by the way : 

  • What is the format of the .cube generated LUT file ? Iridas ? 
  • Are all available adjustement layers taken in account for LUT creation ? 
  • Are blend modes taken in account ? 

Thank you,

EDIT : it seems there is a problem in data order, inverting it in Photoshop ( sorry guys, had to know ) give the expected result, see below :

and the trick in Photoshop

So I'm not crazy.

Is there any official news about this ? 


I don't know, I have not used affinity anymore and I have not even followed the evolution, but if you are here it means that the problem has not been solved...

Can you please confirm which version of the software you are running. If you are getting LUT problems in the latest version can you also provide a sample file and the LUT export options you are using.

The version I'm using is the 1.6.4.104  (Affinity Photo) for Windows 10 64 bit.

Now I have received notification that there is the version 1.6.5
I'm downloading it and then I'll install it and try the LUT again with it.

 

The procedure I used is:

1. Open a document

2. Add some adjustment layers (posterize, color balance, levels)

3. File - Export LUT (there not exist "Export 3D LUT) (I tried all the options to save LUT)

4. Close the file

5. Open a new image

6. New Adjustment layer "3D LUT"

7. Load the file LUT saved (The program does not respond for 2 or 3 seconds)

8. The result is totally different: Only a color change towards red.

 

Note: loading    ".look"    the program has stalled.

 


I attach some files

I tried with the new version (1.6.5.123)

Same result, (variation of tone towards the red), except that loading "LUT.rdl"  that instead gave a variation towards the blue (perhaps it has received ONE of the adjustment levels - color balance - where I had turned towards the blue)
Loading the "LUT.look" the program freezes (does not answer)

I've carried out a small trial using layers and LUTs as follows:

1. Open jpg. file

2. Apply a HSL shift layer and change to a random hue.

3. Export the LUT as a .cube

4. Add a LUT adjustment layer using the exported .cube LUT

5. The result with just the LUT layer visible is totally different from that expected. However with both the LUT layer and HSL layer visible the result image is the same as the original opened .jpg??

I also tried a similar thing but exporting as a .3dl LUT and the result is as expected, that is as the original image plus the HSL shift adjustment layer. So it seems to be the cube export that is causing the problem. I've not tried the other LUT formats.

Hope this helps and, after nearly 2 years waiting for this to be  corrected, we soon see this aspect of the program operating as it should.

Ho effettuato una piccola prova usando strati e LUT come segue:

1. Apri jpg. file

2. Applicare uno strato di spostamento HSL e passare a una tonalità casuale.

3. Esportare la LUT come cubo

4. Aggiungi un livello di regolazione LUT usando il LUT del cubo esportato

5. Il risultato con il solo layer LUT visibile è completamente diverso da quello atteso. Tuttavia, sia il livello LUT che il livello HSL sono visibili, l'immagine risultante è la stessa dell'originale aperto .jpg ??

Ho anche provato una cosa simile ma esportando come LUT .3dl e il risultato è come previsto, cioè come l'immagine originale più il livello di regolazione dello spostamento HSL. Quindi sembra essere l'esportazione del cubo che sta causando il problema. Non ho provato gli altri formati LUT.

Spero che questo aiuti e, dopo quasi 2 anni in attesa che questo venga corretto, vediamo presto questo aspetto del programma che funziona come dovrebbe.

 

I tried all the exporting formats. No one works for me...

HALLO!!!! 
Nothing new?
With version 1.7.0.367 LUT does NOT work yet.
Is it possible to make it operational?

This should be working - Is it a particular effect not working at all.

A couple of screenshots showing your error would be useful.

The result is the same as you see in the screenshots published on 22 August 2018.

Taking the HSL adjustment as an example the latest builds are working for me. Are you using new LUT exports?

Thanks Pauls and tonyjt.
I tried applying 3 different adjustment levels, and then I did the same procedure described above and the result is the same.
I'll do more tests.
What do you mean by "new LUT exports" Pauls?

I meant you weren't using LUT's that had been created in earlier versions. If you're experiencing problems you must be doing something slightly different to us. Could you supply a sample file that you use that goes wrong and I'll see if I can duplicate it
