In the interest of time, without a lot of precision measurements, I'm going to 'emulate' the pattern in the sample, rather than trying to duplicat it. So, we'll need a nice, uniform pattern for the "lines" in the background. Sizing the pattern will be seat-of-the-pants -- looks about like 12 pixels off and 12 pixels on. So I'll generate a pattern and fill a layer with it before blurring.
Now we've finished work on the background, and it's time to highlight our subject, and create her glow. Fitting, don't you think?
Now activate the view of your outlined subject. (Turn the layer on.) Cmd/click or ctrl/click the layer icon for her to generate a selection based on her outline. You should see racing ants appear. Now, choose Select > Modify > Expand and add enough pixels to cover at least part of the "glow" we'll be making. (There are other ways of doing this "glow" but this is the most straight forward and mechanical -- for a teachable moment.)
THIS IS A SIMPLE WALK-THROUGH for producing drop shadows by hand. In some cases you'll want to know and understand this process because you'll need a shadow that does not "drop" from the entire object, or one that you can manipulate as a separate object rather than part of the layer as in the Drop-Shadow layer effect.
This is an object, rastered on its own layer.
simple object
The first thing we'll do is duplicate that object to another new layer.
* Drag the layer to the "New Layer" icon at the bottom of the layers palette, or,
* Use the "Float" command: Command/J, or Control/J for Windows.
