The Nik Collection has been sold to DxO... and is currently still free.
Now that is good news - but one wonders whether Adobe will allow it to be called from within PS because the current version of PS 2018 CC does not even show it as existing on one's system
Mine shows in PS 2018 Terry and it works OK as well.
@AngieDThanks - I've just run the installer again and it's put it into PS
I think DXO wanted the U-technology because they are now using it in their own just released new application.
