Grid Lines

Hello. I processed a .CR3 file and noticed after processing thru Photo AI that there appears to be a grid pattern in the background. I’ve darkened the image to make it more clear.

@wanda.collier Thanks for sharing your image.

This is a known issue with processing RAW files that we’re working on fixing as a priority for this and next quarter.

Are you using the Lighroom plug in? If so, n the meantime you can try using the Photo > Edit in > Topaz Photo AI workflow which will process a TIF instead of a RAW.

We appreciate your patience and understanding as we get this fixed for you.

Thanks, Tim.
I don’t use the LR plug in. It complicates my workflow as I use DPP, then Topaz, then LR. But it’s good to know if I have trouble with a photo I want to keep that I can proess it as a TIF this way.

Thank you.

I am getting the grid using plug in and creating Tiff. So the issue is no just in RAW. And I cannot use the Raw Plug In as it changes the color of the image severely, and oversaturated the image to the point of a useless image. Any ideas? Thanks

Can you send us the file so we can try to reproduce this issue? What filter did you use on the image to get the grid pattern?

I am getting the same issues with CR3 raw files or converted CR3 to TIFF files just like above posts using the following; DeNoise AI, Sharpen AI, and Photo AI. What I have observed when moving around the image in the suggested software, can show a slightly yellow/green tinge grid within the image. When releasing the mouse button and waiting for the update to finish, it shows that portion of the image on screen to look okay. Moving away from that updated portion of the image shows the grid bug that was not in view at the time of the update. It appears that the grid bug saves with the image. Hope this helps.


We are working on a fix for this issue in the Remove Noise - Raw models. It should release in two weeks.

If that works, we will be fixing it in the Upscaling models as well.

Sharpen AI and Topaz Photo AI sharpening does not have this issue. If you are seeing it there, please send a screen recording or screenshots so I can check that.

This is still an issue in 2.0.0 where I have a very light background color, upsize the file and denoise and deblur the image, then import back to Lightroom Classic 2023. If I darken the background, the grid becomes more and more apparent. See attached where I purposely darkened it too much.

We are working on a solution for this. I am checking with the researchers to see where we are in this process.

Hello all, I have a build for Topaz Photo AI which has a potential fix for the grid artifact when upscaling.

Please install the below Beta build and try upscaling some images to see if the grid artifact appears.
Mac build
Windows build

Please share any feedback regarding the grid artifact, if it’s still happening or if it seems to be fixed for you.

Hello, as of 10/6 I am still experiencing the grid artifact in a specific work flow as follows:

  • Process original RAW (Sony A7rIII) in Capture One Pro then round trip to Photo AI 2.0.4 for noise reduction.
  • Then process the TIF file produced by Photo AI in Capture One with my go-to B&W app Silver FX Pro v.6.
  • In images with large uniform areas such, as cloud free sky, the sensor grid is immediately noticeable and more so as the area is darkened.
    Note: If I reverse the sequence and go to Silver FX Pro first then to Photo AI the grid does not appear.

Are you using Mac or Windows? Could you send the Raw file and the TIF produced by Topaz Photo AI so I can try to reproduce this issue?
