I have paid for and been using Nik plugins for 15 plus years, I can't even remember when I started. I want to say maybe 2002??? I have used Nik plugins in my workflow ever since. I remember when Google bought out Nik and then gave the software to everyone for free 🤬. Now DxO has purchased Nik and wants me to re-purchase what I already bought years ago. I don't think Nik has changed much by the way.
In my journey to completely replace my Adobe Suite I found Affinity Photo 1.6 to replace Photoshop. It works great, better than Photoshop, for me, I absolutely love it. Affinity Photo released it's update to 1.7 and the Nik plugins don't work in 1.7 which is a bummer. Knowing this before I updated I also found a replacement for Nik.
For around the same price as Nik pluggins I decided to purchase Luminar by Skylum. It's an Adobe Lightroom Alternative. But for me, it's basically 90% Nik software, but better. You are getting Lightroom and Nik all in one. But wait, it gets better. Tooling around inside Luminar under plugins I found my Nik Plugins. THEY WORK inside Luminar. (I am using the latest version of Luminar)
This just might be best of both worlds! If you want to use your older Google Nik Collection Plugins with Adobe Alternatives, check out Luminar by Skylum and see if it will work for your workflow as it does for me.
