I enjoy capturing lightning. Or at least trying to. :elkgrin:
My experience has been it takes the right storm formation to make it easy. If the lightning is imbedded in the rain then it's tough to get a clear shot. When an approaching storm has the lightning out in front of the rain, it's pretty easy.
I just set up a tripod and set the exposure for about 15 seconds, F8, manual focus to infinity and then sit back and remotely trigger the exposures one after the other as the storm moves in. With an active storm, your bound to catch something.
These were from last year's Tucson Monsoon.
