So I don’t know why but DNG files (4000x3000) are being saved and resized (256x192) and becoming pixelized thumbnails instead of the 68 megabytes that they say they are.
Steps to reproduce issue:
I have opened the DNG 's directly in photo AI the most current version as of right now today and it happens over and over again.
Topaz Photo AI [v1.x.x] on [Windows/Mac]
The DNG saving in that way is expected behavior. The small dimensions you are seeing is for the JPG preview which is included in the DNG file.
If you open the DNG file in an application with DNG file support such as Lightroom, Photoshop, or other image editing applications, it will open the full image.
We are working adding a full size JPG preview to the DNG file so the dimensions display properly and it can be opened in applications without Raw support.
The odd thing is (you correct LR and Affinity) is does not in Microsoft photo?
Microsoft Photo does not have support for DNG files.
