Well, PC users take heart! Macphun software is coming to PC's. No, I have not used it on a PC, nor do I have any connection with them beyond being a user.
http://tinyurl.com/y93ahs6mI have been trying out Luminar on my Mac as a PS/LR plugin, and I really like how it handles noise. Better, IMO, than Nik. In fact, I like the way it displays edits as overall. Free trial period, of course.
Seriously, when Nik became free for all comers, that was it's death knell. How long does anyone think Google (or anyone else) is going to support software that can't support itself? IOW, there's no money in it.
