Question

Lightroom Classic 14: AI noise reduction still creates wrong colors

  • October 15, 2024

No improvement in Lightroom Classic 14.0: when using AI noise reduction, the colors in images with raised shadows still have a clear purple or magenta cast. This happens at values of less than 100%, at exactly 100% the color cast is gone, but then the noise reduction is much too strong. With other denoise programs such as Topaz AI the problem does not occur. When will this bug be corrected?

    There are a couple of things you can do:

     

    1. Example files would be of a huge help. Pre and post-Denoise
    2. Provide Information about the Camera 
    3. Provide information about your system - particularly your GPU.

      Right now, we just don't have much to go on, and I cannot reproduce the issue you are describing.
