Importing an enhanced DNG give wrong pixel dimensions

I wanted to compare the results of topaz sharpening on an image upscaled with Photoshop Super Resolution to using the native upscaling within Photo AI, but have run into a curious issue. When I open the upscaled image in PhotoAI it reads it as a lower resolution file (but not the original resolution!) Exporting from Photo AI gives a file at this new resolution.

Original image: RW2 file at 8368x5584
Upscaled with PS SR to 16736x11168 and saved as DNG
When I open this file in Photo AI it reads as 8393x5632 (different than the original resolution?)

I have replicated this with a couple files and happy to send samples securely.

I don’t think TPAI knows how to read a Super Resolution dng file. The file probably also has the original raw embedded in it, and that is what TPAI opens.

That is probably the actual dimensions of the raw CFA prior to debayering.

Would you mind taking a screen recording of this behavior so I can see exactly what is happening?

Loom is a great free application for this: Loom | Free Screen & Video Recording

Here’s a quick capture. Hopefully this gives you a better idea of the weirdness…

Thanks for sending over that information.

I have reached out to some of the developers and they suspect that the enhanced DNG file contains the original information and the application is opening the original for some reason instead of the upscaled version.

The recommended workflow would be to use Topaz Photo AI before enhancing as this would give the best results. Currently the enhanced DNG is operating as an unsupported file type.
