When I was on excersize with the army in Germany there was a fantastic lightning storm, we were camped in pitch black in the middle of nowhere. I set my old 35mm SLR camera up on a tripod and pointed it down the valley, I set it to manual shutter and pressed the button and held the shutter open till after the flash then released it and wound on for the next pic. The pictures all came out perfect, they showed the lightning bolts and it also showed the whole valley where it had been illuminated. I lost those pictures along with a lot of irreplacable family ones when I seperated from the wife in 83. I'm damn sure she threw them out but can't prove it.
