Camera Raw: Super-resolution brings weird artifacts

Hi there,

I just tried out the enhance and super resolution feature on an HDR image and was really impressed, until I found these strange artifacts that can be seen everywhere.

I combined 3 images into an HDR image in Lightroom, then edited the photo in Lightroom and exported it as a DNG raw file to then open in ACR and enhance. I also tried stripping the image of the edits and enhance the original combined HDR, but it still presented those artifacts and lines.

Can anyone help me with this?

Thank and best regards,


Max

Thanks for the report. Camera Raw engineering is looking into this issue.

you might want to post on the ACR forums instead:

Do you see the same Super Resolution DNG artifacts when using just one of the three original raw files?

Hi there,
I am having the same issue. I've read several forums around.
So far i tried to:
- update displaydriver

- uninstall a lot of crap (as it might interfere with the processing)

-dis, and enabled GPU processing

- tried RAW images, .tiff files, .jp(e)g files. all give "same" artifacts 
- tried switching bit depth and color spaces preferences in ACR

It cannot be related to storage (the preview also shows artifacts) so i doubt it is a .dng issue as nothing has been saved to file, during preview! (but ofcourse i can be mistaken)

custom built win10 pro computer 32GB RAM, everything is processed in RAM as i use a RAMDISK.
core-i7 CPU, intel HD530 card

camera type is Canon5D4 (CR2 RAW files)

I found some more; when disabling the GPU rendering features in PS and ACR preferences, at the moment you press "enhance" it still uses GPU.
That is bug. (i'm not sure it is related, but)
