I’ve done some further test. If I open and upscale the original file in PhotoAI all EXIF are contains in the exported file (exported as .DNG)
If I using the PhotoAI plug-in in Lightroom (via menu “File - Plug in Extra”) the upscaled image doesn’t include the EXIF data.
As far as I see this is a bug that has been known for a long time.
See here:
Photo AI issue writing EXIF data - Topaz Photo AI / Bugs and Issues - Topaz Community
Update 3.1 of Topaz Photo AI - exported files STILL missing metadata (EXIF, GPS, original date taken, etc.) - Topaz Photo AI / Bugs and Issues - Topaz Community
I think it’s time to finally fix this bug.
Instead of constantly implementing new features, you should first address the known issues and bugs and solve these.
