Hello/Hi/Greetings,

Reading the doc even further I discovered the "Manage Properties" plugin which allows Piwigo to read and use EXIF and other file properties.

Its very useful, I was able to add what I want to show except for a couple of EXIF fields that show in each of my files inside EXIFToolGUi and other programs I use to edit myfiles, but for some reason Piwigo doesn't show them.

In the https://exiv2.org/tags.html Standard EXIF definitions the fields I want to see are any one or more of these

0xa432     42034     Photo     Exif.Photo.LensSpecification     Rational     This tag notes minimum focal length, maximum focal length, minimum F number in the minimum focal length, and minimum F number in the maximum focal length, which are specification information for the lens that was used in photography. When the minimum F number is unknown, the notation is 0/0

0xa433     42035     Photo     Exif.Photo.LensMake     Ascii     This tag records the lens manufactor as an ASCII string.

0xa434     42036     Photo     Exif.Photo.LensModel     Ascii     This tag records the lens's model name and model number as an ASCII string.

In Manage Properties, the drop down list includes 0xa434 so I chose that but nothing shows in the gallery

It also includes 0xa432 but shows it as an array where you have to choose 0,1,2,3 but none of those produce anything either.

Maybe the solution to this means creating a local config entry, but that takes me back to the same issue I already reported concerning LocalFiles editor.

Any ideas?
I'll keep reading

Thanks
Ian
