Either way, it could lead to better tools."
Then feeding ACR conversions, the supposed grid structure would look to an AI system as genuine detail to preserve and enhance, in whatever mode it was operating.Īgain speculating, if so, it could lead to improvements in Raw conversion and/or of the "training set". If so, it might suggest that in using the specific images used for training (the training set), the various models were derived from under-represented common ACR conversions. One photographer reported that he was getting banding until he switched raw converters, and then the banding disappeared.īart van der Wolf (who is actually doing some testing for Topaz) has speculated: "Actually, this (potential) Raw converter dependency is a very fascinating observation that will take further investigation to validate. Though this isn't banding, over on the luminous-landscape forum there are a number of threads on the new Topaz AI programs and users are reporting a variety of issues, some of which have been solved due to user feedback. I thought it was very unlikely that it would, but now we're sure.Įxported from LR, without any sharpening (slider at zero in the converter, none in the export dialog) I'll find an image from myself that shows the same effect and do the same.Įdit: just did, but I processed an image to about the same size as yours from Lightroom, it gave very similar artifacts in Sharpen AI along the blue sky top border. I'd say it's a bug and I would report it to Topaz.
What is strange that if you enlarge to 400% and just look at the processed preview of a small area the worst artifact is always in the right top corner of the preview, irrespective of where exactly you are in the image along the top border.Īnd in your original file I can't see anything (not even a hint) of slightly different colour blue pixels that the program might mistake for detail that needs to be brought out. Click to expand.I downloaded your original image and ran it like you did and get exactly the same result, I varied the top two sliders ("Remove Blur" and "Suppress Noise") a bit but again the problem persists.
