I have recently purchased Topaz Sharpen AI 1.4.0 and while it does some amazing things I have found an issue which mainly seems to occurr when I use the Stablize option. If I zoom in to 200% I can see vertical banding in some images, especially those shot at ISO greater than 100.
Here is an example, original at 200%
It’s not an issuewith display in the App, as the banding can be seen when the image is taken back to Lightroom or Photoshop (where the captures were taken from)
It might be an issue with ISO noise, or it might be an artifact of my camera - I am using a Pentax K3 mkII which doesn’t have an anti-alias filter.
I tried using Denoise AI first, in case it was an issue with the software seeing the noise as detail to be sharpened, however the banding is still present when i subsequently apply Sharpen AI to the image
I realise I don’t have the best graphics or CPU performance as my PC is using an AMD A8-7650K Radeon R7.
Has anyone else come across this issue? I haven’t had a chance yet to turn the camera’s AA software filter on and try a few shots with that to see if there is any difference
