Wonderful! But how the bloody hell did ya do it B?

I made a transparent electrode of salt water between 2 glass plates, connected one electrode of my high-voltage generator to the salt water, the other to the oak leaf on the glass, and let the camera take a long-time exposure through the glass.
Warning, if you want to imitate this: This kind of photo takes serious high voltage. My generator outputs about several ten thousand V peak, and, more importantly, has a
pulse energy of up to 1 Joule – that can be lethal

I’ve seen this type of photography on a science documentary. Don’t they call it “Curlian Photography”.

Steven,
this is somewhat similar to Kirlian photograohy, but it is not the same:
Kirlian is done with high-frequency high voltage, such as from a Tesla transformer (take a look at www.teslamania.com). The high voltage in this photo here is from a spark inductor (with some fancy electronic triggering electronics that I built many years ago), which outputs pulses of HV. You have to be much more careful with those, i.e., don’t touch, but they are friendlier to electronics (like in a camera), as long as the camera is some distance away
