Thanks guys!

Taking images of lightning is really just one of those trial and error things. Believe me some of my early attempts were dreadful!

If I could suggest one thing it would be to always expose for the brightest and closest bolt you think you might get. You may end up underexposing a few of the weaker ones but at least you wont blow the hell out of that potential wall hanger shot! I used to spend a lot of time trying to recover blown out images, now I just tend to bin the underexposed ones.

I'm certainly no expert on the art of photography but happy to help in any way.
