Adam Block lightning picture.

Taken by Adam Block in July 1998.
This picture was a twenty second exposure using Fuji
800 film with a 50mm camera lens. To most people's surprise, good
lightning shots are not difficult to take. You need to have a manual
camera with a bulb setting, which you set on a stable surface or
tripod. All that is then
necessary is to keep the shutter open until at least one lightning
flash has occurred, and then release. You can also keep the shutter
open for any number of lightning bolts of any kind.
However, certain conditions make taking such pictures easier.
If the sky is not especially dark, then one must shorten the
length of an exposure while waiting for lightning.
Also, if the storm is very close the lightning will be seen
over the entire sky, so having the storm at a distance makes it
easier to capture many strokes (and a bit safer as well).
This particular storm was around fifteen to twenty miles away, and you
can see how well the lightning illuminates the ground.
