[Topaz Denoise AI plugin on a NEF RAW file (was Dr.)]

Thank you both! This greatly simplifies my workflow. Changing the Develop Assistant properties did the trick. Thank you also for the pointer to ExifTool. The test above doesn't apply to my situation, which was when the denoising was done in Topaz Denoise AI, and there was a possibility that the metadata recognized by Topaz is different from that recognized by Affinity Photo. However, now there is no reason to do that now that the plugin is working.

Thanks again.

[Topaz Denoise AI plugin on a NEF RAW file (was Dr.)]

I am fairly new to Affinity, but I can't find any answers to this in the forum. I want to use the Topaz Denoise AI plugin. It seems to be installed correctly and works when I open a tiff file. If however, I open a Nikon raw file (.NEF), the plugin is disabled, as expected. When I develop the image, the plugin is disabled. If I duplicate the background pixel layer and select the copy, the plugin is still disabled. The only way I can use Denoise AI currently is to export a tiff from AffPhoto, denoise it, and re-import the tiff file -- I am concerned that I may lose metadata in doing that.

What am I missing? If I have to convert to tiff, can you confirm that I won't be losing metadata?
