The actual set up for this is simple. The goal was to make it look like she was outside at night. I used one softbox on a studio strobe on her left. On her left and behind her I used a speedlight with a blue gel.
I took 10 - 15 photos total. She then went to bed.
I processed the base photo in Lightroom and then went to Elements for adding the snow.
I used a royalty free photo of the snow. I am not sure if it is actually snow, but it looks right.
I created three copies of the snow in layers. On each I used a different setting for a Gaussian blur filter. This makes the snowflakes look like some are close and some are far away.
I then masked out a bunch over her face.
