I use all of the Topaz programs but as a plug in with Photoshop CC. When I use them I am still working on a RAW, unsaved image. I am sure they will work with a JPEG, but like any JPEG image, you are looking at an image with limited abilities to be manipulated.
HTH
That is right. "Limited Abilities". For instance, Topaz Denoise AI can do a fantastic job on noise, if you started with the RAW file. But using the JPEG, it can't do nearly as good of a job since for the most part, the noise seems to be baked into the JPEG.
Note: I don't actually use the RAW file with Topaz. I start with Lightroom and call Topaz from it. Lightroom then sends a TIFF file to Topaz and when done, returns the result to Lightroom. Or I use it with Photoshop.
