Lightning's tricky. By itself, it's boring. Usually, shooting from a "close/convenient" spot makes for a boring photo. The scene needs the right amount of light so the camera can wonderfully expose most of the dynamic range our eyes can see, so that one can include foreground elements that make for a striking (haha) photo (the same applies to fireworks). I experimented at dusk, set shutter between 2"-3", almost wide open aperture, and adjusted ISO to expose the landscape as I saw it (tripod/remote/infinity)...decent captures that way. I chose that shutter speed so I wouldn't have to be so quick with the remote. As it got darker and my foreground started to become completely shadowed, it was much more difficult and eventually impossible to expose with the lightning, then I was stuck trying to expose lightning by itself, at which point, I stopped and just watched the show. It was a good learning experience; I'd never had this kind of chance before, because there was so much lightning spanning most of my visible horizon, increasing my chances of captures.
