Topaz is telling me the Samsung S24 Ultra DNG raw files are not supported.
Currently the S24 Ultra DNG files are not part of our Supported Cameras.
We use LibRaw’s open-source software to handle raw files within Topaz Photo AI, and unfortunately, LibRAW does not yet support this camera. The Photo AI release will support the added camera models as soon as they update their list.
In the meantime you can convert those files to either a TIFF or JPEG and they should work with Photo AI.
