Lit Xmas tree using Adobe PS?

[Mimi]

I want to jazz up a photo of someone standing in front of an outside Christmas tree at night. Although there are a couple of lights on the tree, my photo didn't capture any glow. Can I add some glowing lights to this tree? I've tried using a layer with some brush strokes, but I can't make the little flakes and stars actually glow like lightbulbs. Any suggestions? I'm using Adobe Photoshop CS. Thanks in advance!

I posted the same question on another board and got lots of help. Someone there explained it very well for me, so I no longer need the information.

shutting down the lens as far as you can will add the twinkle effect.

in ps experiment with the filer section. try playing around with the unsharp mask parameters.
