My film camera has a wide angle lens but my dslr does not. The first would have made it easier to capture a larger slice of the sky instead of randomly pointing in a general direction hoping lightening would fill my frame. But I didn't think to drag it out at the time. And in that case, it would've been another month before I had the film developed. Pros vs cons. Either way, I do not condone standing outside during an electrical storm with a metal tripod.
The first image was left open the longest, probably 90 seconds. You can tell by the cloud movement. The second was more like 30 seconds since I felt I captured that bolt and that was all the light I needed. The third is probably somewhere in between. White balance was on auto so that's where the crazy purple hue comes from. I kind of liked it though and left it as is.
I follow a number of photography sites and thought this was an interesting video on night photography worth sharing. I've yet to shoot anything leaving my lens open for hours at a time, but I keep telling myself it'll happen one of these
