Lightning Photography Techniques

[random]

Hi guys,

I'd like to hear a bit more about preferred techniques for lightning photography, now that I'm back up in Brisbane, and this weekend is supposed to be another 'good' one.

Up til now I've been doing exposure times of between about 4 and 10 seconds, taking lots of pictures, then picking out the ones where lightning actually hit.


Any other techniques to try out?


{edit: these were taken a few weeks ago, tripod, exposure around 4sec. I'd taken a few more with exposures around 10sec as well}
