This shows red sparks. This effect is created by taking a normal white flash shot first to give the correct white background, then switching to the red filter and running the sparks for 10 seconds or so while the camera is recording.
It is all one single exposure and is what the camera sees, not a photoshopped effect added later.

DC sparks from my flyback supply with a 0.2 uF capacitor providing a spark energy of perhaps 10 joules at 10 kV. In air this spark will jump less than 1/2 inch (1.25 cm) but water surface tracking means that this will be many times longer and gives a widely branching long spark suggesting a much higher voltage.

Paraphrasing Monty Python -“None Shall Pass”. A Tesla coil in my high voltage shed. Standing room only. I need a bigger shed as I am running out of safe standing room!

Coin shrinking a Japanese coin to half its diameter while preserving details. Bonsai for coins. You can still see the Japanese characters miniaturized on this one yen coin. “Continue reading” for the details of the huge currents involved to make small change. Continue reading
This is my take on one of Tesla’s famous photos in which he demonstrated remote power lighting a globe.

A Tesla coil makes dramatic lightning like displays of electric power such as these sparks to me in a Faraday Cage.
The “Modern Thinker” above is my interpretation of Rodin’s classic statue the “Thinker”. It conveys the concept of the modern electrical age with the barrage of electrical interference in our lives. So much is happening and demanding our attention that it is difficult to “think”.
Believe that?. Me neither. I just like making pretty spark photos….
By the way, no photoshopping anywhere on this site. It’s all what the camera sees. Check out the Modern Thinker page for the construction of this.
Above shows “Tesladownunder car theft protection”.
Above shows a Tesla coil with rotating long breakout point looking dramatic on time exposure of 22 seconds. The “Eye of Sauron”. The two photos above have been seen by perhaps 500,000 people worldwide now since Feb 2007 and resulted in well over 100,000 hits to my site. It was featured on some big sites and hundreds of blogs and was also popular in Russia and Japan.
Above is an animated gif showing the effects of rotating the rod on top. In real time it takes 7 seconds per rotation.
Above is my recreation of Tesla and his wireless light globe compared with the original.
No photoshopping – ever.
Above, the Dalek cage. Just what you need to get up close and personal with lotsa volts. And you can even use a phone in it.
Above: How about red sparks?
Above: There are lots of other colors to see in multi-colored sparks. These are single photographic exposures through clear and colored filters in turn.
Above, swimming with 100,000 volts. Sure it’s safe. Tin hats protect you.
Above, Tesla coils with sparks from 2 inches (5cm) to 11 feet (3.3m).
Above, a briefcase Tesla coil and sparks in a light globe.
Above, Tesla coils sparks onto my tongue, driving a string of up to 30 fluoro tubes and apologies to Michelangelo’s Creation.
Above, some unusual solid state Tesla coils on the left using SIDACs instead of a spark gap, centre using a Royer circuit and on the right a vacuum tube based coil and its sparks.

This is a Tesla coil with high voltage sparks coming from the end of a rotating rod. It looks dramatic in a long exposure exposure of 22 seconds. The first thing that came to my mind on seeing the photo was the Eye of Sauron.
