Lightning is a powerful way to set your images apart from others and demand a viewer's attention. You can punch up the drama in any foreboding sky with our electrifying lightning creation. Here's how to do it.

Let's begin by selecting a stormy photo that lends itself to our electrifying effect, as shown in Figure A. To follow along with us, download the file lightning.zip from the URL at the beginning of this article and open the file storm.jpg in Photoshop. (Images provided by PhotoSpin. Some images have been modified for educational purposes.) With the image open, it's time to create a new layer to house the lightning bolt effect.

2. Drag the center gray slider to the right this time until most of the clouds have disappeared, as shown in Figure D.
3. Click OK.
