Ultimately, Google, as is their all too customary practice, decided to jettison or kill Nik off in 2015. Google loves to create beautiful tools and workspaces, get users hooked and then yank the whole tablecloth out from underneath them. They do it again and again.
The French company DxO finally bought the rights and picked Nik up again and their hand was now out one more time like I had never ever paid them a single dime.
It gets discouraging. I didn't cough it up. Felt slightly abused by the whole process. But it mostly still worked except for what I considered my most important feature.
And suddenly one day, after an Adobe update, the programs were no longer functioning together and instead I got a blank color screen. Oh well, would have to do the best I could without the darn thing. And I did..
But I knew a secret trick with Nik, I could add structure in Silver Efex and then create a luminosity blend and all of a sudden I had an incredibly powerful and beautiful unique tool to work with that delivered something quite rare and visually marvelous. I really missed it although it must be used with a very light hand.
