Bonsoir,
Thanks for the speedy reply.
I used the RAW plugin, accessed through File>Plug-in Extras >Process with Topaz Photo AI.
To be comprehensive, I made a short test of the External Editor plugin, accessed through Photo > Edit in > Topaz Photo AI… The resulting TIFF file shows the correct lens info.
Best regards from France
Sounds like the same problem as Metadata Changes .
