Not sure if this is what you're looking for.. but here's the way I do it:
In Corel Draw Graphics suite.. (sorry, know it's almost sacrilege here, but not an adobe fan.. been using Corel since Warp OS/2). Create a good photo with a white background.. (I use seamless paper with two softlight strobes on the sides, blocked to prevent light spill) and another softlight for the mainlight), looking for a soft, almost flat lighting. Create a duplicate layer, overlay it to add contrast. merge and create another duplicate layer, use a slight gaussian blur (two to three pixels, as a rule, but mainly to your taste) and then a smudge brush to give some of the features (example, the hair) a "paint" effect. Merge the layers together again, then using NIK, I use a old photo effect to create a Elgren/Vargas effect, grain to zero and brightness as I like.. hope that helps. (BTW, Corel Paint Shop Pro X4 also allows the same thing and even includes the full Nik Color Efex Pro 3.0 filters) http://www.corel.com/corel/product/index.jsp?pid=prod4220093
Very quick and simple.. and it's a great fun addition to a "boudoir" or "glamor" session.
