Digital Darkroom

In response to my previous post, I got a question about how to get the glow in the last (fourth) photo. Here is my response:

For the last picture of the young lady, Alison, part of the softness came from the effect of a direct backlight, which was the sun coming through the studio window.

For the post-production.
I used Layers in PS5.
1) Load the picture.
2) Duplicate the picture in a new layer.
3) Blur the picture with the Gaussian Blur filter.
For a 800x533, use a strength of 4
For a 1200x1800 pic, use a strength of 20

4) Then go to the composite menu on your Layers palette (I've included a photo of it, and put a pink ellipse around it)


And you'll see a list of choices. The default is NORMAL.
What you want to look for and choose is SOFT LIGHT, this will severely increase the contrast by calculating an algorithm using the highlighted layer (which in your case is the duplicate) and the layer immediately below it (which is likely the Background or the Layer 0)

The glow come from the Gaussian Blur in step 3.

That was the end of the email. In fact, I did that same technique with some modifications specific to the photo on the following, which was 800x533, Sharpen settings were Amoun 125%, Radius 0.3 pixels, Threshold 1 Level, dropped the mids on the Blue Channel curve, but that's all standard anyway (oh, and I cropped and resized the picture):
