I’ve discovered a technique that’s changed my life, via Tips and Tricks for PS CS included with the CS upgrade: Lens Blur.
I followed the instructions to the letter, albeit blindly, as I am unfamiliar with paths and channels. It worked great and I’m elated, but why do I need to do all that fancy stuff with alpha channels? I tried it again, simply cutting and pasting parts of my picture into a new layer and then applying the blur. It seems to have worked just as well.
It would be very helpful if someone could define "alpha channel" and perhaps distinguish it from "path" and plain old "channel" or simply provide a source for that info.
Thank you.
P.S. BTW…When the new filters "box" comes up, it seems the right side of it is cut off, without a scroll bar to access it. I can work around it, of course, but it’s odd.
