See image below for one method I found.

*My method works pretty well but there are some quirks. Mainly that the 'circleness' is lost near the edge of the image. Click here to see what I mean. Also the strong blur is a real performance drain.

Guess I was a little vague. Here's a photoshop mockup of what it should look like.

uberzev -- take that snippet you posted above, plug it into Adjustments > Tone Curve, and then plug a Curves > Wave component into the Tone Curve.

I'll soon approve a snippet by Quasimondo in which he shows how to do zoom -- maybe that will help.

Vladimir, can you please edit my topic title? I meant to ask about a Radial Gradient and not about a Radial Blur smile:cry:
