I then went through several diff custom edits using only one edit at a time and saving. Then reopening and viewing the two photos side by side.
The biggest problems were with the sharpening and dehaze tool. Both the lens blur and unsharp mask were totally diff than original edit. It was like I had not sharpened at all. Huge diff seen when using dehaze. When I first downloaded Topaz Studio this was not a problem but only presented after updates were added.
I checked the Basic Correction, Bloom, Black and white, Abstraction,Precision Contrast, Textures, HSL Color, and Curves. These all gave a true rendering when saved.
