John Paul Caponigro in his book "Adobe Photoshop Master Class," and here:

http://www.peimag.com/pdf/pei03/pei0506_03/caponigropei0506_03.pdf

describes his method for working Photoshop 7 features into 16-bit format
through 8-bit images, going "back and forth between modes."  I've tried
working through the process as he describes it, but get nowhere.  I'm
obviously not getting it.  Are any group members using this process, and if
so could someone describe it in more workable terms and workflow than Mr.
Caponigro's?  Thanks much.
