Yes sorry, AI Clear.
The settings are not really relevant. The problem is the difference in what Topaz Studio is showing in the (HD) preview and what is really written to file when you click Save (or what is really returned to Photoshop when you click OK).
Just in case: I set AI Clear ‘Remove noise’ to ‘high’. I set ‘enhance sharpness’ to ‘low’ ,and I set ‘recover details’ to 0. Basically, fix as much noise as possible.
But again. my problem isn’t the results. It seems there is a bug on ‘saving’ the result that leads in artifacts.
My input file is always a RAW file from my camera saved as TIF (I tried both 16bit and 8bit) and I try saving as TIF. So no compression artifacts there. Or I try from Photoshop using Topaz Studio as a plugin, but then there can’t be any jpeg artifacts as well, since the whole chain is also uncompressed.
The artifacts also don’t really look like compression artifacts to me, it somethings looks more like a maze pattern, or like some random parts are just unprocessed.
Maybe this is a better example. This is a screenshot from Topaz Studio’s preview window:
This is good, and I’m happy with the result.
But upon saving (or returning to Photoshop) I get this:
I just started the trial for ‘Reduce Noise’ adjustment, and I get the same effect there (even worse).
It seems Topaz Studio just adds artifacts to the output.
If I try to apply Topaz Studio from Photoshop without any adjustments at all, I get a very slight color-shift but otherwise I get input back as output without anything done as it should.
But even adding a basic but heavy ‘Gaussian blur’ yields artifacts in the output (although far less than with reduce noice and AI Clear).
Here is an example with a simple ‘blurs’ adjustment, type ‘gaussian blur’, ‘amount’ set to 0.25, ‘preserve edges’ left at 0.
This is the Topaz Studio preview window (good):
But this is what is returned to Photoshop:
So I editted the title of the thread, as it seems like a general problem in Topaz Studio and not (directly) related to AI Clear.
Are the debugging options, or a way to disable GPU support or something to test if that helps?
