setup: tripod, cam on manual exposure, f/22 (f/16 one of them), bulb mode, iso 200, manual focus on lens and put it on the infinite loop.
the point in the direction you see the storm and hold shutter button to keep it open. wait for lightning to strike and let go, or you can wait for multiple strikes if they are coming down fast enough.
i really need to get a remote shutter. any suggestions anyone? prefer wireless.
