Sorry, if this is a basic question but look at this photo:
Honey on Flickr - Photo Sharing!
There is probably a softbox used but then her facial skin almost looks a bit like soft silicone or non-shiny rubber/plastic.
Also, her eyes are crystal sharp but her iris has some sort of glow in them. Look through some other photos and you'll come to know.
What kind of post processing seems to be used here ? Any idea ?
The photo has been added to PSDTUTS pool, so I suspect there maybe a tutorial on psdtuts ... will have to try hunting for that.
