P: Strange moiré patterns with the Canon R5

[andydub1]

I was editing some events photos and started noticed a strange pattern with low light files, and with the Lens Correction feature activated. I increase the exp so you can see better the lines. ISO 6400. Check the file

LightRoom Cloud?

Wrong forum, Catto - this is the LightRoom Classic forum.

posted there as well, idk why adobe use confusing names in forum. at least product name should be lightroom cloud however it is adobe photoshope lightroom in reality.

The names are indeed confusing. The metadata in "after.jpg" says it was generated by Lightroom 7.1.2 (Windows), which is Lightroom Desktop, part of the "Lightroom ecoystem".  Adobe never uses "Adobe Photoshop" to prefix the various names of Lightroom in these forums, even though that's what Help > About Lightroom says.

As expected, I see the same effect using LR Classic 13.1 and CR 16.1 with the attached .arw, using the develop settings in "after.jpg". (I extracted the Develop settings used in "after.jpg" to _DSC0041.xmp, attached).  But the pattern is clearly visible with just Exposure = 2.5 and Enable Profile Corrections:

@Rikk Flohr: Photography, consider moving to Camera Raw Bugs?

It's 2024 and I still see the issue in Lightroom 13.1. How much longer is it going to tak to fix this?

@Rikk Flohr: Photography Yes, Pattern is visible even after AI Denoise. It's been almost a year. Adobe should fix this issue.
