Kirk and Alan, I tried working with virtual copies of a layered file, and if I changed the visible layer and resaved in PS, it changed all the virtual copies. It sort of defeats the whole purpose if I make a new copy (which LR labels EDIT), because I'm still ending up with multiple copies rather than the different variations of the one that are "virtual". See the thumbnail of the layers pallet. I have a "master" color image from which I created three additonal B&W layers: 1) B&W, 2)sepia with border effect, 3) B&W with border effect. Then see the screen shot of the file saved again toi "expose" the sepie layer. It changed the virtual copy to match.
I suppose there just is no way to do what I wanted except work in PS. I guess the only way is if I do everything in LR, but I've yet to achieve anywhere near the quality B&W that I get from Silver Efex, nor the variations of effects.
