I think he just left the camera in place, took several pics with different breakout points and merged them after that.

Note the glowing between metal pipes around coil and earth. I wonder if it is only when arc strikes them or it is result of capacitive coupling..?

suprised WOW! I'm afraid for all my technology when I run my coil 20feet from my house, how well do your electronics hold up to that kind of electrical noise? BTW that is one of the most amazing photos I'v seen.

The glowing between those pipes and the carpet only occurs during arcing. They pipes are actually PVC scrap wrapped with aluminum tape. And its actually only one pipe, i moved it around from shot to shot.

As far as the technique goes . . .

1. Take several shots on a tripod using same exposure. Take as many as you need.

2. Load the images in Photoshop

3. Copy each image, and paste is as a NEW LAYER in photoshop.

4. Now, for EACH layer, use the LIGHTEN BLEND method on the layer palette. This will basically keep the background unchanged and only add the "light" colors (i.e. arcs) in the image

5. Once its complete, then FLATTEN layers and export to your favorite image format.

Wow! Did you get any little burns on the walls from that? I had a little SGTC striking the wooden footboard of my bed once, it lit up orange but no visible burns. It was nowhere near that power, though!

Thanks. Yeah, i get lots of little pinhole burns in the drywall. No big deal since this is just a storage room. As far as electronics go, i actually have a computer right behind me in those photos which is about 10 feet back from the coil. Never have any problems.

Thats amazing. When I run my 1.3kW sgtc it plays havoc with the phones and the TVs. I am too afraid to leave a computer pluged in while im coiling.
