    Grid pattern in background

    This shot is SOOC converted to Jpeg.

    First I denoised it with Topaz set at Denoise 20, sharpen 20, recover original detail 5, color noise reduction .10. I also tried it set to 10, 10, 0, 0 and had the same results. The tennis net looking grid pattern was there upon opening it in ACR. Has anyone seen this before?

    Re: Grid pattern in background

    Looks like it could be banding. I only encountered it once with a photo SOOC so I skipped that image and moved onto something else. Since it isn't something I deal with and lack first-hand experience with how to resolve it, I am not able to point you in the right direction, Andy. But do some online searching until someone else hopefully can assist you.

    Obviously, Topaz is doing it. I'd probably set the Denoise to 75 and the Sharpen to 0... and then reverse those 2 parameters to see which one is introducing the pattern...

    I'm w/ @FredKingston on this one...

    Although I'm not sure any settings change will fix it. Topaz has a long history of grid artifact issues. This article may help, but it may not get rid of it completely:

    Here is a thread from Luminous Landscapes that describes the same issue with Sharpen AI. It shows the same type of grid banding that you are experiencing.

    https://forum.luminous-landscape.com...topic=129798.0

    And then they had a second thread because the same type of issue was present.

    From their site:

    This will cause the image to process on the CPU instead of the GPU. This will probably make your image process slower but will eliminate the artifacting.

    Making it slower is not a good option for me, it's pretty slow already!

    It seems to be a common problem which is too bad, otherwise it works very well.


    Someone mentioned Topaz Studio 2 on another site and said it runs better on his old Macbook. I'm downloading the trial to see how it performs on my PC. Thanks for the tips!

    The only person I know of here who might be able to offer additional insight would be @BackdoorArts - maybe Jake has encountered this issue?

    I've gotten banding with and without Topaz. Learn to use the Suppress/Reduce Artifacts slider to help control those introduced during processing. You can also use masks to apply the Topaz edits just to subjects and not to the background. If there's noise in the background then do 2 passes in Denoise, first to reduce noise and then a second to sharpen.

    I'm shooting RAW so I tend not to see them until the JPEG is exported. When I do I edit the JPEG and will introduce Gaussian blur in the banded areas to minimize or eliminate them.

    I was at the end of my trial and my old PC struggled with Denoise so I uninstalled it. In the future I would like to have a better PC and take the time to learn more about it. I heard that Studio 2 is more friendly with not so up to date PCs so I'm trying it. I understand that it is more of a "Denoise lite" though. Thanks Jake!
