Notice the background..
Original

used Stabilize + 0.7 Remove Blur

this one is more pronounced.

I have seen similar issues with a blue sky only with stabilize.
As sky needed no sharpening just layered back to original.
It’s as if stabilize is forcing a sharpening from nothing so it creates the banding.
As with all Topaz products that are stand alone you can’t layer within the app or run as a plugin so it just creates an extra step.

Bob, thanks for pointing out the banding. I haven't used the Stabilize mode much, but I will watch out for that artifact.
Paul, you can run Sharpen AI as a plugin in Photoshop. That's what I almost always do. Maybe you meant to say you CAN layer or run it as a plugin?

My bad.
I was thinking about gigapixel. I don’t believe it has plugin capabilities.
Sharpen AI works well as a plugin.

Bob, I am cusrious, whether it is banding - what was on the background there - just the foliage or was there a net with that pattern? Perhaps the pattern was restored?

I had the same thought. It would be interesting to brighten the background of the original image to look for a pre-existing pattern.

No net. Just some foliage. Trees mostly

Looks like there was part of a brick wall back there.

yep... but it was trees. anyway, you get my point that was algorithmic banding..

Bob, I've noticed a different banding pattern on some images that are processed in a particular way, in areas very similar to your background. I'll describe it when I have time. But in the meantime, could you tell us how the Sharpen AI processing was done? Did you open it from Lightroom, or another program? Using SAI as a standalone program, or as a plugin? On a regular layer, or a Smart Object?

created a flat TIFF, used AI Sharpen as a standalone.. I don't use LR..

I am using Photoshop CS6 in Win 7 x64 and Sharpen AI as a plug in.
I have noticed a weird pattern of "color bursts" show up on the top edge, or border, of my landscape pictures.
I have attached an example.

I have also tried monochrome images but SAI works in color and creates output color image from grayscale input. When viewed close I have seen fine grain color noise. Albeit not as dramatic as you example.
