Improve your 3D renders!
~By Ntrik_
1) First things first, cut your 3D render out! (there are so many ways in this, Im not going to name them all :P)
2) 2nd, you can duplicate the render it self (multiple times if it pleases you), and use transformations to give it either different looks (perspective, 180 degrees, etc...)
3) Give all those renders Screen/Lighten blending.
4) Now, Merge them all, and duplicated it again (only twice more)
5) Give Radial Blur to the duplicated one
6) For the 2nd duplicated one, give it a Gaussian blur (3~5, or lower, depending on Render size etc..)
7) now, for the first one, give it a lighten/overlay/softlight and for 2nd one, give it a soft light blending.
8) Now you're done! Here's an example of what I got from this:
