lighting effect

http://misery.subnet.at/v10/freeze/ddr_0049_downward.jpg
Thats an example of a pic im going to use. Now my question is not, how do i do that pic, but in the middle of the pic and to the very top, where all these different lights are sorta blended together forming something. I dont know what it is called, but its like a bunch of different lights shooting up..
Well i was just wondering.. How would you go abouts doing that?
Any help is appreciated.
Thanks.

Hi chicken!

It looks like that some clever blanding combinations have been done to achieve those lighning effects. Usually, you try different options until you come up with something you like.

Perhaps you can achieve something similar using these two great special/lightning effects photoshop plugins:

-Knoll light factory
-Genesis V2 Pro

I don't know if I can post both download urls here, but you will find them performing a search at google.com

Hope this helps you!
