Lightroom photos dissociated from presets

[Bertrand C]

Hi everyone,

I've a big problem with my Lightroom catalog. Almost all my photos from 2010 to 2017 have been dissociated from thir settings (presets and camera profiles) I gave them. This is days of works gone and I'm not quite sure how to fix this, or if there is even a fix.

I think what may have happened is that, after reinstalling my Mac, I reopened my Lightroom catalogue without copying the presets back into their respective folders. So I assume Lightroom found no presets for all my photos and changed them to the no-preset "default".

Do you think this is what could have happened?

I have quite a few backups of my catalogues over the past years. I've tried to re-open them with the presets installed, but it's not helping.

Has anyone had this issue before and know a fix?

Did you import the photos into your catalog? Or synchronize folders?

IIRC- In the past, if you deleted a Develop Preset from the computer, then the Develop editing steps applied in the Preset (Exposure, etc) were preserved in the photo in the catalog. (A metadata filter for "Develop Preset" would indicate {Unavailable Preset} )

With recent changes to Presets that incorporate the "Treatment & Profile" checkbox, any missing Profiles may be causing the total reset to "default"

I am thinking you must restore all your Presets AND Profiles (from system backups?) that you have used previously.

Presets and Profiles are not included in Catalog backups, so restoring a Catalog backup will not be helpful.

As dj_paige​ also points out- Re-importing or Synchronize folders will also reset photos to 'default'.
