First: Here are a few tips on how to capture images of an electrical storm with a camera…
Make sure your surface is sturdy – Use a tripod or prop your camera up on a rock, pillow, etc.
Use A Long Shutter Time – Set the timer to go off at 30 seconds, timing is everything when it comes to lightening.
Pay attention to composition – Frame the lightening to add perspective to the shot. Use buildings, trees, or anything else that gives the image viewer an idea of the size of the electrical storm.
Use Manual Focus – Because you are shooting at night you want to manually focus on the sky and leave it in that position.
Shutter and Aperture – Set your camera up with a long shutter time and a wide aperture. Your shooting from a long distance so a wide aperture will give you a shallow depth of field.
Use Photoshop – or some other editing software to enhance color, stack images etc. for more dramatic effects.
And here is how you can create images of electricity without a camera…
For those of you who want to try making images of electricity without using a camera Phillip Stearn has figured out a way. If you expose your film with 15,000 volts of electricity you can achieve some interesting results. By using peel-apart instant film, pouring household chemicals (i.e. bleach) onto the film and then touching it with a neon tube ballast to electrocute the surface you are able to create some very interesting images. Check out this video from Phillip Stearns to learn more about how he creates images with electricity.
