Getting good lightning pictures is a matter of knowing when to take the picture. When you see the lightning, it's too late.
Here is an android app that solves that problem. It buffers the video from the cell camera so you can capture images after the fact. I've downloaded it but have not had the chance to try it out.
Yes, it is cool, and in the many years since Lucky Ben Franklin flew his kite, very little has been done to figure out any practicable means of harnessing the tremendous power (and integrated energy that is in the quads) of lightning.
There are places in the world where tremendous levels of power (and integrated energy) are possible on lightning alone, if we know how to capture (some) of the potential and current without simply exploding the object we were inflicting with the lightning bolt.
I also find it very interesting how the many branches reach out looking for the low impedance path, then BOOM!
