LUT export/import do not work properly

macOS Ventura v.13.2
Hardware acceleration ON
Problem description:

After exporting LUT and then importing it back o the image, the image outlook is not the same, eg. very low contrast.

Size of the LUT do not influence the result.

The same problem appear in Affinity Photo V1.

Can you explain your workflow a but more, please?

How did you get a LUT to export?

If it was already in the image, then wouldn't adding it a second time have to change the results?

[Mariusz_F]

Workflow is typical I think:

1. I make adjustment to the image eg. white balance, curves, etc.

2. I export the LUT

3. I open the same original image, with no adjustments

4. I import LUT what was exported in step 2.

And the final result is like on the images attached, that the new image has a different look, no contrast, etc.

Thanks. The two images you've included look almost identical to me. Perhaps you could provide the original .afphoto file including the adjustment layers, the .cube file you exported (and a screenshot of that export dialog), and the new .afphoto with the LUT applied?

Hi @RalphMara,

Welcome to the Affinity Forums

Unfortunately this issue is still logged with our development team to be resolved at this time - I will be sure to 'bump' this with your post for you now.

I hope this clears things up!

Hi @Dan CI have the same issue, which is unfortunate since I was planning on using these LUTs for batch processing my vacation images. It seems that exporting Luts works better when the adjustments are not embedded in a group in the layers panel.
