I was fairly impressed with the ability of Topaz Sharpen AI to reduce small focus errors.
Unfortunately, Photo AI seems to lack the focus deblur controls of Sharpen. And Sharpen AI is no longer supported.
I didn't know that. I have Sharpen AI and access to Photo AI v1. Since Adobe Denoise AI came out I stopped using Photo AI and kept Sharpen AI around. Last time it was updated was in 2022 and not is it supported any longer, you can't purchase it either. It is a mature product so it works well.
This is what Photo AI v1 did when it was just released in 2022. I realize it has changed a lot since then which includes v2. I'm surprised there would be less control.
