That would be pretty slick if you’d hit it with flash about a 45 side / 45 up with direct flash away from her face to try to light up “just the glitter”..
You could definitely make an attempt to blow the highlights on the white sparkles and doing so would probably even saturate the colored ones a little more and make it glow..
I’d say using 2 flashes off camera one for fill and one for effect on the sparkles would be awesome.. the tan background definitely needs to be dark for this to be super interesting, but i like the concept.. I may give it a shot =P
