Topaz Photo Pop was a menu item in Adjust 4, but was gone in Adjust 5. Fortunately I still had Adjust 4 on my laptop when I got my new computer and had to do a fresh load. Adjust 4 is no longer available for download, at least that I could find.
I run this as an action on a new layer. Here are the settings:
Adaptive exposure: 0.27
Use Adaptive Exp: 1 (means module is on)
Details boost: 1
Details threshold: 0.25
Details radius: 36.79
Details Mode: 0
Use details: 1 (means module is on)
Adaptive saturation: 0.09
Color Regions: 10
Saturation Boost: 1
Use color: 1 (means module is on)
Noise threshold: 0 (means module is off)
From here on I will leave it blank. The action copied all the default settings, but none are active.
This was a copy job, don’t ask me about the details of the process. I simply copied the settings from Adjust 4.
If you have Topaz 4, Photo Pop is one of the presets. So far as I can tell, Adjust 5 does not even have presets. If I am wrong, please drop me a note.
This works really well on my images at 70%. But it will make a halo if you have very light/dark transitions at a horizon. The halo is very large so sometimes it is hard to see when looking close.
When it makes a halo, I either paint it on, or delete it and use color pop which adds more saturation, but does no sharpening and leaves no halo.
