  1. Hi Chris, with the new beta 514, juliep's example works in manual lens selection without adding a lensfun file, but does not work in automatic selection.
  2. Hi, great news if you use the Nik collection by DxO 2.3 : Viveza 2 works fine : https://forum.affinity.serif.com/index.php?/topic/79748-color-problem-with-nik-collection-plugins/&page=4&tab=comments#comment-553503
  3. Hi. I had not looked for lack of time yet, but I confirm that since the update of the suite Nik by DxO 2.3, the call of Viveza 2 since Affinity Photo beta 486 works perfectly with a zoom factor of 20% and 100% at home. I specify that I use a color workspace 4 times larger than the sRGB.
  4. Are you sure ? The DxO PhotoLab workspace is limited to Adobe RGB and I don't use it for this reason. Your profile has exactly the same gamut as the Adobe RGB, I use significantly larger workspaces. The plugin works very well with PS, I don't think the problem comes from him ...

    Colour profile conversion for DxO

    Hi Gabe, you can see here for example : https://forum.affinity.serif.com/index.php?/topic/99436-colour-profile-conversion-for-dxo-plugins-beta-180486/&tab=comments#comment-532673
  6. Hi Tom, it's true when the distortion is linear all over the field, but some lenses are known for their distortion in mustache (especially wide angle) and in this case it does not work very well.
  7. And me too ... with great impatience!
  8. Hi Chris B, unfortunately, it does not work. I tried this including with the exact syntax that appears in the exifs ie the original HSM termination and several other combinaisons. In any case it did not work and it seems that there is a problem with the procedure under Windows. This is good news if the next beta improves this.
  9. Hi Julie, I'm well aware ... Usually developers read the topics, but if you have a direct way to let them know, don't hesitate.
  10. Hi Julie, Unfortunately, I do not have good news for you ... I tried with your photo without result. Then I tried to reproduce the issue with one of my lenses that does not appear in the lensfun database, a Nikkor 28-105 AFD zoom. I get exactly the same problem as you (with darktable using the same lensfun file, I could recognize it)! I deduce that this procedure is inoperative on Windows, the video being made with Mac OS. At this point, only a developer can trace the problem. It should also be known that the maintainer of the lensfun base has big problems of disponibility and because of this, lensfun is updated with big delays and the procedure is quite forbidding. In addition, in lensfun, your Sigma lens has been tested with a Sony and not a Canon. The APSC crop factor for Canon is 1.6 while it is 1.5 for other brands. As a result, the distortion values would be a bit distorted. There is also a conflict in your image at the level of the exifs and the maker notes, in these last appears the zoom 75-300 Canon while it is the Sigma which appears in the exifs ... Sorry for not being able to help you ... the hand is to the developers.
  11. Hi Julie, there must be a difference between the name of the lens in the exifs and in the lensfun file ... Can you give me a link to a raw so that I can see what is possible to do?
  12. Hi, what version of lensfun did you download? Are you sure your 18-300 sigma lens is in the slr-sigma-xml file? I see it in the latest version of lensfun 0.3.95 downloaded from the site lensfun and not that of github.
  13. Hi Mark, My monitor is a Dell U2711 wide gamut. The profile is the last one I created, close to the Adobe RGB.
  14. Hello, the use of .8bf files is the reason for being compatible with Photoshop plugins. That said, launching the .exe would not be heretical, that's what Lightroom does ...
