Glow

This is a pretty neat and easy tutorial. It will give your images a nice glow-y effect.

Here's an example:
 

1) Open PS and paste your image.
2) Go to Layer>> Duplicate Layer.
3) Go to Filter>>Blur>>Gaussian Blur. 4) Set the radius to 5.0 and click OK.
5) Go to your layer window and in the drop down menu select either soft light, hard light, or vivid light. Whichever you prefer. I think that hard light and vivid light are more interested than soft light. In the picture above I used hard light.
6) Click OK and go to Layer>> Flatten Image and save your image!

That's it! Hope this tutorial helped!
