Re: How to create blur/lens flare effect? by Cassius Marques on Nov 14, 2013 at 3:58:12 pm
I believe that's called anamorphic flare. Magic Bullet Looks has that as a filter and it includes some customisation along with a lot of presets that already utilize them. (some paid, others come with the package).
Looks is the only plugin that I've seen that kind of effect built in. But you can fake it with some blurred flares like Ted suggested, though the real effect should respond to the image's exposure.
