    Wow, if these really are worms, they are the worst I've ever seen. Maybe I didn't hang around the Fuji X forums enough.

    I wouldn't call them worms. They are more like an offset printing pattern. Fuji Frontier film scanners produced a similar phenomenon. Maybe the boffins at Adobe think this is what people want. How does Topaz Denoise handle it? Pretty well. AI selected Standard, but Clear works better to preserve forest detail. Topaz treatment below.

    What am I supposed to be looking at? Not sure what 'worms' are.

    Zoom into the image 100% Look at the area where the darker green foliage meets the slightly less dark foliage in the background. Also around the contrasting white areas in the clouds close to the blue sky. In the centre of the image. It's a raw processor thing apparently. Adobe is real bad for it, pretty sure you don't get it with Silkypix. It's an X trans thing

    OK- thanks. Not something that would worry me, but I can see how it's not perfect.

    In fairness the posted image has some quite generous post processing going on 😀 I am not a Fuji user and understand that ACR used to be very poor with Fuji raw files, I thought they had supposedly got better , though looking at a few raw samples ACR is still not the way to go with Fuji files .

    The only Adobe software I still use is Acrobat Pro.

    Is ACR not updated as frequently as Lightroom, or at all? Supposedly Adobe "fixed" this problem in Lightroom.

    I bought DxO for Raw conversions, and with Deep PRIME have never seen anything like this.

    So readers can avoid downloading a huge image file, here's a screenshot showing "worms" in "blue" sky.

    Thanks - now I know about it, I'll be on the lookout. But I use Capture One and not ACR to convert raw files and I haven't seen that with C1 (I just looked at one I converted with C1 that had blue sky and it's fine)..

    Looking at the exif of this HDR:
    - contrast +100
    - texture +100
    - clarity +50
    Seems like over the top processing [the maker said it was an experiment], once more not an example of the infamous worms

    I agree you need to be looking at heavily processed images to see the effect or at crazy zoom levels in PS. The first image below shows 100,200 ,400 and 800% crops . At 100% I see nothing at 200% much the same the sky starts to look a touch wormy for lack of a better word at 400% 😀 800% viewing looks bad on any image from any camera . The second image shows the DXO interpretation . I don't have a Fuji camera and borrowed this sample from the X-T5 samples on Dpreview

    Worms are an oversharpening artifact in Fuji X-Trans images. Like many image processing artifacts, they're most prominent in overcooked photos viewed at 100%. Even though the differences in worminess between various photo processing and editing apps are subtle and typically only discernible when pixel peeping, there's a widely-embraced mythology that worms are an Adobe Camera Raw (ACR) issue.

    It's been at least 6+ years since the worms artifact plagued any but the most ham fistedly processed photos in any app. In other words, it's something Fuji shooters are well-advised to be aware of but isn't an issue unless a person goes overboard with sharpening.

    According to my wife if there is a ham-fisted way to do something I will take it 😀
