IMHO LR demosaicing of rafs is still inferior to C1 and Iridient.
I agree, and if I have a shot where I need to extract maximum sharp edges from tiny details I will use one of those or Photo Ninja.

I am really curious to your findings. Would it be possible to share examples procesed with the recent versions of the software? You use Fuji a lot more than I do. I only use the x100v during biking trips and street photography. In addition, my eyes are probably not as good anymore to see all subtleties.

Suggested starting Lightroom sharpening settings for X-Trans 16MP:
Amount: 17
Radius: 1.0
Detail: 74
Masking: 0
The basic idea is to be low on the 'Amount' and high on the 'Detail'. If you have the feeling to increase sharpening, increase the 'Amount' slider, but only a bit.  Going from 17 to 30 is a big dose of added sharpening. Don't know if this applies to the newer 26MP X-Trans sensor.

Thanks!

Especially interesting for Fuji X-trans is the "Enhance details..." found under the Photo menu of Lightroom Classic.

It is basically a much more elaborate demosaicing process (trained with machine learning), creating a linear .DNG file next to the raw file.

IMHO it does a very good job on X-Trans files.

Thought to share 2 full-size jpegs generated from Lightroom 10 and Capture One 20. Photo taken with Fuji x100V. ISO 160 - 1/30sec - f8. Both processed with Fuji Velvia, HL/S correction. I used Topaz Sharpen AI on "auto" settings for sharpening to get an equal baseline in that area.  Unfortunately file size is limited. I can send full-size jpegs, if someone wants to study the details.  I tried to spot differences but failed to do so (details in the sky are comparable when highlights are dampened a bit more in Lightroom.
BTW: I took this photo to explore the possibilities of Luminar and Photoshop for sky replacement.

Lightroom 10.0 example:


Capture One 20:



I haven't checked for other types of photos, especially portraits (which is one of C1's key strengths IMHO)

Try comparing the two in Photoshop by layering and selecting Difference as the Blend mode. This does show differences, which I can post if you are willing for me to do so. I also noticed that you posted them in Adobe RGB, which some monitors may not represent properly.

There has been much discussion amongst Fuji users about Adobe's processing of X-Trans files. Many have switched to Capture One or Iridient. For example, here is a discussion on an official Photoshop website. https://feedback.photoshop.com/conversations/lightroom-classic/camera-rawlightroom-classic-fuji-xtrans-support/5f5f45684b561a3d424a11b0

Adobe itself recognises that there are issues with its X-Trans processing, and when releasing Enhance Details stated it could "resolve issues that some customers reported with their Fujifilm X-Trans based cameras".

A problem with Enhance Details is that it creates a large additional dng file, in the case of a Fuji file I tested this was 100MB greater than the original raf (which was, of course, retained). So it is not something one would want to use for every image; and I don't want to have to think about whether an image would benefit from it before deciding on the processing workflow.

Photo Ninja and Iridient Developer do a good job on X-Trans files. Iridient also created X-Transformer specifically for the purpose of demosaicing X-Trans files and creating dngs for further processing in LR.

Having said all that, I prefer to leave scientific comparisons to the experts.

An interesting method, Anthony. I am curious to your findings. I could see differences in colors and aberration handling but no artefacts. Was I wrong? Feel free to post your findings since I may misinterpret what I see. I am curious what yours are.

BTW, I switched to Capture One anyway and do not miss LR at all. I only use Photoshop for specific corrections that are hard to o in C1 and stacking (focus, exposure, panos). It takes some time to get used to C1 but after "getting it" I like it better than LR. I still have to check if Affinity Photo can replace PS in my workflow.
I am also considering a workflow for NEF conversion that starts with PhotoLab4. I am impressed by its capabilities for processing NEF files.

Thanks, Peter, this is the result of layering one image on the other and selecting Difference as the Blend Mode. I also made a Levels adjustment to brighten the image.

I am not really sure what this indicates as to artefacts as colour differences are picked up. However, on closer inspection I think that in the C1 version I see more detail in the grass below the bush by the river on the lower right; but it is not easy to tell and could relate to specific processing settings.

I agree with you generally about C1, and I like that it has layers with luminosity masking, which I use quite a lot.

Thanks for sharing and analysing, Anthony. Much appreciated! Your blending looks a bit different than mine. Don't know why.
I turned sharpening off in C1 and LR but just noticed that I used a different clarity setting in C1. Sharpening for both images set to auto in Topaz Sharpen.

Actually, I think I may have discovered a new art form!
