That's an amazing photograph...!
I've been sat in my chair here for ages, wondering how he got it...?
...hours of anticipation of something unusual happening...?
...sheer luck...?
...a camera set on a tripod, with a flash/light detector attached to the shutter...?
I never cease to be amazed at photographs of lightning...
It must take hours of careful setting up all the equipment in the anticipation of getting a successful photograph of a specific lightning event...?
This chap was VERY lucky to capture both an active Tornado and a flash of lightning at the same time...!!!
What are the chances of that happening during the average week with your Brownie camera and a roll of black and white film...LOL...!

P.S. A
genuine? photograph like that should be covered by Copyright...LOL...!
