I noticed while working on my windows workstation today that Topaz was introducing rogue “hot” pixels or NaN’s into the images upon opening them. They are RAW files directly from the camera. I thought it may be a graphics card problem so I opened the same file on my Macbook Pro and I’m including a screen grab with the RAW file in Topaz (left) the Topaz RAW denoise (centre) and the same file opened in Affinity photo.
You can see that the rogue pixels in the Affinity photo file are not visible and you can also see that Topaz is crushing the blacks and colours compared to Affinity.
I did a search and see others have flagged this but there doesn’t seem to be a response or a fix, at least that I could see.
Steps to reproduce issue:
Select file
Open with Topaz
Topaz applies the standard RAW denoise, but the pixels are still visible even if the denoise is turned off.
Do you have a link to the other issue you have seen with similar issues? I want to make sure the information is related before merging these two threads.
Would you mind sending in some more information to get a better understanding of the problem you are having with this particular type of image? Please send the following information:
The original image file.
The processed image.
A screenshot or description of the settings panel so I can see what adjustments were turned on.
You can securely submit your image(s) to my Dropbox using the link below.
My apologies on missing your responses, I’ve received the files and have been able to replicate these hot pixels you are reporting.
Can you confirm with me if these problems are occurring with both AI models RAW Normal & RAW Strong while using the RAW denoise enhancment?
In the meantime, I’ve added this information to an open development ticket our team has open and will be sure to reach out to you on this thread with any more information.
