I think it's better to post it here because everyone can know the fastest method of bloom rendering trick.....
Ok,lets get started.
First,I will take this rendered picture using 3dsMax 5.After that open the Adobe Photoshop.

After that,duplicate the layer first!

OK,now go to image/adjustment setting & click at brightness/Contrast settings.[I use +36 as brightness,+80 as contrast]

Now,Desaturate the image.

& now,apply Gaussian blur.

My setting is 5.6 as the pixels radius.
Finally,change the master image setting to linear dodge.

For now,you image has got a bloom on it!
BTW,playing with the master opacity,gaussian radius,Brightness,Contrast will greatly effect the image.So the best way is,try to expreriment with it......
