How to create intense light streaks

I did a little research and picked up a couple of tips from similar tutorials to present a walkthrough on how to create intense light streaks flowing around an object or person.

Firstly find a subject to base the flowing light streams on. I picked out an image of a drinks can to relate to the original piece of artwork that inspired the subscriber.

Using the Pen Tool draw a path around the object, make the selection and paste into a new document using a black background.

Reselect the object by CMD/CTRL + Click on the layer, go to Select > Feather and enter 1px. Inverse the selection and hit delete.

Duplicate the layer and set the layer style to Multiply, drop the Opacity to suit.

These tips help the object blend with the background a little more realistically by erasing out the hard edges and altering the lighting and shadows.

On a new layer draw a circular marquee and add a Gradient fading to black with a colour of your choice, here I've chosen a cool green.

Transform the gradient and squash it vertically to add a little perspective.
