I have been very impressed so far with ACDSee, the RAW conversion quality is very good (Canon & X-Trans) and it does run all Topaz Plugins including ReMask … well worth taking a look at.
This image was processed from RAW to ReMask & Impression in ACDSee, exported as TIFF and then used Affinity Photo just to add the signature and resize … (It can be done all in ACDSee)
