The exposure time on these photos range anywhere from a few seconds to over a minute, I basically put it on manual ("bulb"), held down the shutter release button, and waited for a strike. When I saw one I let go and repeated. These aren't as close up as some of the others I've taken, but I'm really happy about how many I managed to capture! You can also check them out in my photo section or as a slideshow. If you're interested, you can see my previous lightning photos here.
