The JPEG I can understand because it does depend on the quality of the input that would determine the level of artifacting but for the TIFF it seems a little unusual as I haven’t seen artifacting like that in any of my TIFFs.
I would also try the TIFF using the Low model because there seems to be a lot of Chroma noise also. The release notes for AI Clear (1.11.7) state the following:
AI Clear Model Strength: Low, Medium, and High now represent their own models. Use Low and High options for Luma noise… but I’m not sure why Medium actually applies heavy Luma correction.
You may want to check that your JPEG output was 100% and that the TIFF was with no Compression and 16bit and no transparency.
- Also make sure that output sharpening is turned off.
