Issue: AI Denoise right side purple/red vertical lines in dark photos for Canon

  • Lightroom version: 7.2 x64 [ 20240214-0910-27200e9 ] (Feb 14 2024)
  • OS Version Number: Windows 10 Home (2009)


Steps to reproduce:

  1.  Upload a dark or underexposed RAW photo
  2.  Use the AI Denoise Tool (The issue for me existed with any range from 1-100)
  3.  Right side of photo will have vertical purple/red lines. It is more visible if exposure is increased.

Expected result: No purple vertical lines/bands on right side of photo
Actual result: Purple vertical lines/bands on right side of photo

 

I also tested with other properly exposed pictures, and the purple bands do not show up when the picture is well lit. The right side vertical lines show up in a pitch black picture as well as an underexposed picture with a little light. I took the images with a Canon EOS R6mII. I attached images of my issue.

 

Thank you!
