Thanks. I think you may have accidentally posted different links than you intended--when I look at them, they don't seem to explain this--but but a very helpful post anyway. I have almost always used Nik from Lightroom, and I completely missed the fact that in PS, because Nik filters are attached to a layer, you can apply them to selections. Very helpful. thanks for posting this.
No Dan...John was talking about special effects on people and also using Nik's Software...the links is about Nik's lessons and the process that I use with people are different but if I want some special effects, I selectively isolate the people via inverse selection and use the special effects on the background itself. I hope this helps clarify that point...
Perhaps this isn't the place to mention this but, I have just learned that I like the results when I use NIK Color Efex Darken-Lighten Center instead of vignetting. The effect is far more subtle...

Lighten Center at Default:
Often vignettes are too strong - this one is very-very subtle but, IMO, it does focus attention on the subject.
This makes sense! If you get the image just the way you want it and lighten the center, the center would be too light.
I will often, when working with NIK, globally change an image before selecting the critical points using the Control Point technology and then adjusting the critical points.
The results on Joey's image are so subtle that my wife couldn't see the difference until the two images were seen side by side.
Do you remember which tutorial mentioned this process...
