I don’t think DXO Pure Raw supports the Fuji X-Trans 40 megapixel raw files (yet). It will use one of its options to demosiaic them, and it’s better than LrC default, but not optimized for X-trans, I don’t think.
Most people don’t understand (DXO has done a poor job of marketing) that Pure Raw is not “just a noise handling plug-in.” It goes in and copies the original underlying raw file, and takes it to DXO Pure Raw where it uses its own demosaicing routine, lens correction modules, sharpening, noice handling, and most impressive, its detail extraction slider that has the unfortunate name of “force details.” The results are excellent and where noise handling is concerned (a small part of what DXO does) it is superior in all my tests agains both Adobes new AI Noise, and Topaz.
The only down side to DXO Pure Raw is if you have unusual lenses that they have not made lens correction profiles for. E.G. my two GF Tilt-Shift lenses. It also took a long time for them to do Modules for lenses like the Nikkor Nocht 58mm f/0.95. But over time their inventory of profiles is getting broader.
The other down side is that it is slow, so not viable to run all your captures through it as a routine workflow. But, it has an amazing feature for your “worked up” keepers in LrC. It takes note of your edits in LrC and reapplies them to the new DNG that it produces when it returns them to LrC. The difference in rendered detail is significant, and all my files that I am going to print are run through DXO Pure Raw and then fine tuned as necessary.
It is an amazing program, little understood, IMO. I have both GFX and X-Trans 40MP cameras and I can’t wait for DXO to release an update for the 40 MP sensor.
