This is just a small version of the original full frame scan.

* though to be honest, my success rate with lightning photography in the Film era was pretty low, so I didn't have a huge amount of material to sift through.

Quick like lightning. Thank ya, senor. From my early film days I think I've a grand total of two that are of any worth (and a fair collection of bright clouds to accompany it). Digital days certainly brought new life to *that* particular quest innit. Cheers - that shot is fantastic regardless.

Ha. Somewhere (and I really don’t know where), I have a photo of a laser show on the side of a mountain.

It was accidentally (and somehow perfectly) illuminated by a lightning bolt at just the right time.

The annoying thing is that it looks like a perfectly normal photo taken on an overcast day...

Reviving again, this old thread. It’s very interesting a subject and I’m super curious what this lightning Photo you took looks like, Is there a new link to share perhaps?

I’m keen to try out the LX in some interesting night / light scenarios!

Thanks
