There was an update to LR today using AI to enhance the RAW conversion process, but the description seems to indicate that Pentax isn't one of the beneficiaries. Wonder if this is correct interpretation.

Adobe's latest Lightroom CC uses AI to 'enhance' RAW images

Not sure I read it that way, just typical poor journalism. If this supports Sony sensors no reason for it to not support Pentax. Updating now so we will see.

It supports Pentax DNG, but not pixel shift.

I've tried it; doesn't seem to help much on the landscapes and wildlife shots I tried (and consistently crashed on one cropped Pentax DNG shot). Enhance fine details in raw images

Enhanced detail about "Enhanced Detail" is here: Enhance Details | Adobe Blog

Ok, the "enhance detail" function is located under Photos>enhance details. I selected a Pentax DNG file and used the enhanced function on it. The estimated time to "enhance" was shown as 40 seconds. Clicked the button and waited. The computer created a new DNG with the term 'enhanced' appended to the file name. The image is completely black, and a second test resulted in the same black image.

I then tried to convert the Pentax DNG (version 1.2) into an Adobe DNG (version 1.4). The conversion worked fine but a test with the enhance detail function again resulted in a black image.

So I conclude @Spodeworld's conclusion was correct and Pentax was left out. Puzzling to me as it is supposed to work on a DNG file.

Did you do anything different to the file? Was it shot in DNG? What camera?

[rangercarp]

I don't think the article is saying it only works on those listed camera brands. It looks to me like the author is just giving some examples of Bayer sensors and an example of X-Trans sensors. Did they also leave out Panasonic, Leica, Phase One, Hasselblad, DJI, Sigma...?

What 'raw development' software does support pixel shift? {I was under the impression that is not common}

[Paul the Sunman]

It says 20 sec for me on a mac pro, but hangs at about 80% done. No further progress after 5 minutes.

UPDATE: Ha, it's done. A new enhanced version is there. It's not black. Perhaps jatrax's black image was just a placeholder before the file had been written; it takes way longer than advertised.

Damned if I can see any enhancements! The file was enlarged from 50 MB to 177.5 MB though.

Maybe you’re right that those are only examples. It would be strange if they excluded Pentax from a key improvement.

FWIW, DXO photoLab2.0.0 says it supports the K-1II both PEF and DNG. Since I don't have a K-1II pixel shift image to test it with I'm not sure about Dynamic pixel Shift. The K-1 has been supported since ProOptics 11.2.0.

[superdave]

It works on my K-3II DNGs but the improvement is really subtle. I think you have to print large to see the difference, but this is slightly sharper and better if you take a close look. The result is probably more obvious on Fuji images as LR used to have a poor support (demosaicing) of Fuji RAWs.

[rawr]

The new 'enhance detail' function works fine on the K-1 DNG's I tested it on - standard DNG, even in-camera HDR DNG. Very modest improvement in detail, but evident.

The best thing about this update is that finally I can actually see Lightroom making use of the GPU of the [modest, low-power] Nvidia GT 1030 video card in my photo PC to do real image processing. Compute intensive operations like detail enhance fly along on the GPU while the normal PC CPU sits practically idle.

[Ishpuini]

To quote Matt Kloskowski : "it's for pixel peepers". Or perhaps when you print very large, but even then there are better (image stacking) techniques to get a higher (and more accurate) resolution if you know up front you're going to be printing large. Matt did a little demo in his new features youtube video, and he actually had to zoom in 4:1 to see the artefacts the "enhance detail" improved on.

Pentax is using Sony sensors so.... they are supported

was your Image black from the beginning?

Can we just move on from this? It works. He just didn't give it enough time to finish.
