Lightning can sometimes be a couple of seconds long. If you're ready 
with a responsive camera, you can catch it. The light comes to you at 
light speed, but the rest is a lot slower. There is the usual small 
exploratory strike from the ground to the cloud, and then the big 
discharge from the cloud to the ground. This discharge takes some 
time, and can be caught with quick reflexes. The same goes for cloud 
to cloud discharges.
