Help recreating this burst of light effect?

I was wondering how I could go about making something like the burst of light I have attached.

I just found a similar kind of tutorial which could be useful, any tips on how to modify it for my own needs?

Or even better could you suggest another more appropriate tutorial?

Thanks for looking, much appreciated.

The mentioned URL really has some good tips. I think you should search on net for some better tutorials.

hhi,
there a lot of tutorials but a little tip think outside the box a little....
instead of searching for sun burst, how about lens flare, star burst , star flare, etc... it can make a big differernce on search results....

now i came across a couple of tutorials that are more like what your after.. the first part is basically creting the effect... then after that it adding your color...
