Artefacts in Topaz processed images

[Howard Worf]

Doing some further testing with Topaz plugins I have come across a repeatable and widespread issue with colour artefacts appearing in extreme highlight areas after an image has been processed with most of the Topaz suite of plugins. So far I have found the issue in Adjust, Clarity, Black and White, and Detail. I have the latest releases of all of these plugins.

I am attaching 3 files, the first showing the source image, the second the preview from Adjust, a the third the resulting image in Affinity. These are all crops from a larger image.

 

Source PEF upload was prohibited.

Hi Howard Worf,

This is a known issue with 16 bit images when using Top plug-ins. It happens the same with Photo for Mac.

If you convert them to 8 bit, they are processed correctly. Issue logged to be looked at.

Thanks. As you say, 8 bit works OK.
