Custom Lens Profiles handling

[T_MZ_2019]

In Affinity Photo 1.8 a new feature was introduced enabeling the user to select lens profiles from a dropdown list in develop persona. Underlying dialog is split into four tabs "all", "recent", "favourite", "detected". From preferences dialog you can add custom lens profiles into a folder on the harddrive (Default C:\ProgramData\Affinity\Photo\1.0\LensProfiles). These custom profiles are not loaded into the "all" tab during the program start. So you won't be ablte to load custom lens profiles by manual selection. For these custom lens profiles the program behaviour is the same as in previous versions of Affinity Photo. All lens profiles (pre compiled and custom) shall be loaded into the all tab of lens correction dialog.

Hi @T_MZ_2019,

Welcome to the forums. 

They should all show up in "All". Can you attach the XML so we can have a look?

Hello @Gabe,

obviously I made a mistake. In the custom lens profiles from 1.7 I had to dismiss manufacturer in the model tag for detection purposes. Starting Affinity Photo 1.8 with that, I could not find the lens in the "All" section of develop persona. Finally I added manufacturer to the model tag of my custom lens profile and all lenses Show up in the Dialog. Removed the manufacturer again for testing purposes, but I can't reproduce anymore. So this thread can be closed.

However, here is a part of my working Version of the custom lens profile from %ProgramData%\Affinity\Photo\1.0\LensProfiles:
