Going through some Aurora shots. RAW file. In autopilot before trying and adjustments the preview is showing me some crazy square artifacts.
Steps to reproduce issue:
Topaz Photo AI [v3.04] on [Mac M2 Max MBP]

Hi John -
Just uploaded a screenshot. The marked up screenshot shows where the artifacts displayed on the preview. I didn’t actually process them yet.
Kind of embarrassed - I forgot which was the original file. I’ve attached a RAW from the set and I think that was the one. I took a bunch of photos.
In the past when I have had artifacts with TPAI it has been with exporting lower quality jpegs. This time I didn’t even begin the process - the preview of the autopilot setting displayed the artifacts.
Thanks for your reply and for sending in that information.
I was able to replicate this grid pattern you are receiving with Topaz Photo AI while working with the ARW file you sent in. I will note that our team has open tasks regarding this problem, which we are currently working on and hope to resolve in future updates.
I have added your information to this tasks so that I can contact you once we have resolved this problem.
We have noticed this grid artifact appearing when using Raw Denoise on MacOS Silicon M Chips. Is this what you are using?
We reached out to Apple as it seems their hardware is causing it. The code that Apple uses to process machine learning models on the M-Chip neural engine is working in a way that creates a grid artifact between the processing blocks.
The last time our developers spoke with Apple, they said they would try to fix it in a macOS update; however, we are not sure which one yet. We were hoping that they would fix it systemically instead of through a MacOS update, as users below that MacOS version would still have the issue.
Let us know if you notice anything else or if you have any questions about the workaround.
Just upgraded to PhotoAI 3.1.0 on Mac.
After using any Denoise tool I notice a subtle checkerboard pattern or a subtle grid-like windowpane pattern of darker or lighter lines - so far mainly noticeable in the sky of my landscape images. Has occurred on multiple images. Sometimes the artifacts appear as a checkerboard pattern of lighter and darker squares. Other times they appear as light or dark grid lines. They are subtle and only noticeable in certain places.
Starting with a DNG from Lightroom Classic. No artifacts visible in original DNG. Tried several different ways of opening in PhotoAI.

I think I have experienced the same issue, although I’d describe it as denoise adding faint horizontal and vertical bands to low contrast areas of the image.
I have attached two images and the PhotoAI log. The original image is a section of a photo with part of an aircraft wing in front of a gray sky.
Steps:
Applying the same Dehaze treatment to the original image does not produce the bands.

MacBook Pro, Nov. 2023, Apple M3 Max, Sonoma 14.5
If it would be helpful, I can provide the Photo AI log.

Hi,
I wanted to sharpen and denoise but the image did not come out as expected. I noticed magenta patches in the images and the colours are different.
In the exported images you can see what I mean. I also exported a set that makes it more clear to see.
Steps to reproduce issue:
Topaz Photo AI [v1.x.x] on [Windows/Mac]

Hi John,
I just uploaded my system profile to your Dropbox.
May be I should also mention that the files I tried to sharpen and denoise are raw files.
Hartelijke groet,

I’m having problems with visible tiling in some images with high contrast or where I want so enhance sharpening for effect. The tiling becomes so excessive that I cannot use the dng denoised or denoised+sharpened images to generate the images that I want. I notice this most with cloud and high contrast range sky photography. Is there a way to reduce the amount of tiling?

John,
I uploaded the original file of one type of image that I have trouble with, an NEF file, a final image of what I was wanting that was processed from the NEF file in Affinity, the DNG file from Photo AI, a screen shot of the processing that shows the tiling in Affinity as I was generating the type of image I was wanting, and finally a screenshot fro Photo AI this morning of the settings that would have generated the DNG. I have noticed the tiling anytime I have a high contrast image or where I want to boost local contrast in Affinity or in DarkTable.
My case may be very atypical since I shoot with a very specific goal in mind, and in cases that requires sharpening and increasing clarity and local contrast beyond typical bounds.
Thanks for taking a look at these. I shoot with a Nikon D850, and typically a Nikon 200-500 zoom.

John,
I uploaded the .spx systems report on my MacBook pro to your dropbox this morning. Hope that helps.

On a basic denoise and sharpen I’m getting literal squares in different exposure zones on an image. As well as a generally blurry overall result. There is no real improvement.

I have uploaded the requested files to your dropbox. It’s pretty clear that the Raw Denoise is the issue, as in the samples I provided I only used Raw Denoise and the problem is present.
