Dear Donald,
Which article in Shutterbug was that? Bear in mind that I don't always see the magazine, and that articles are sometimes published quite a long time after they are submitted. There are some of Marie's pictures in some of my books, but I don't remember any in Shutterbug.
Marie tends to use fairly simple lighting, one key (high and to one side), one fill (lower, in the other side) and at most a couple of other effects lights -- rarely even that. Really, it's much like any other portrait lighting; any book on lighting should be OK.
What sort of effects are you trying to achieve, and are you shooting colour or mono?
Cheers,
R.
