TY to Tori for the tip on this one.  The photography magazine, Rangefinder, has an entire feature on how Twilight themed photoshoots are becoming popular.

Photographer Hernan Rodriguez explains how he went about getting the look (see page 5)

“The Twilight craze is huge with the young generation. Teen guys are hip
to this style, and girls want a guy who looks like this. We were after a shot
with senior Jason that had a dark, mysterious look with blue undertones,
which presented an interesting challenge. We couldn’t shoot Jason in
the middle of a dark mystical forest. We would have had to scout a place
and bring in generators to light it up like a Christmas tree, so instead we
brought the forest to our senior in postproduction.”
