Re: [TCML] Ultra-high speed movie of lightning arc channel formation

[David Kronstein <david_kronstein@xxxxxxxxx>]

I built a high-speed digital camera like this as a project, and while 
it's probably not as fast as the camera they used, I may be able to 
shoot something interesting.  It basically records a constant 80 
megapixels per second, so you can trade resolution for speed, eg. 
640x480 247fps, 320x240 940fps. I doubt it's possible to see streamer 
prorogation, at least at any meaningful resolution, but I'm sure the 
video would still be interesting.

Seeing streamer prorogation would probably require a rotary mirror film 
camera, those can record millions of frames per second, although only 
for ~100 frames.

I'm currently getting my Tesla coil up and running again, I'll be sure 
to get some videos once it's running.
