I found this slo-mo lightning video really interesting.
Quite different to what you might imagine.

i've seen something like this, caught it on video too.

What kind of speeds would you need to do this? VERY cool!

I've always wanted to do some high speed video, although high speeds camera's can range into the $10,000's

Btw some more interesting stuff on this, including slow-mo TC clips, can be found on ZTR

Hi guys,

Yeah I'm certainly a fan of that guy's videos.

He has recorded some pretty bizarre phenomena like multiple lightning strikes triggering each other, stepped leaders nearly reaching ground and then deciding to turn back into the cloud they came from and those mysterious cones of light emanating from the tips of leader 'fingers'.

There are some videos featuring nice leader growth from grounded objects as well. During growth and propagation of the leaders numerous small, very rapid discharges (''recoil leaders'') occur in the previously ionized paths similar to those post-discharges in Lichtenberg figures.

I especially like this one, it's black and white but very magical. I like how the arc fades away almost completely at 1:55 and then violently reignites sending those plasma balls in apparently random directions across the cloud. Best watched in fullscreen and HQ, of course.

Leader emerging from ground, note the cones of light projected from the tips of leader branches as they move upward.

Cheers,

Marko

>_< I bought a Medium speed camera (300 - 1200fps) and i have been waiting for weeks to get a thunderstorm. But in the mean time I have been re-filming a lot of older experiments but in slow motion!
