Capture lightning in a photo

“I shoot this last summer. At first my idea was to capture the true thunderstorm timelapse after I failed capturing the lightning with my old Samsung phone and my iPad by just “shooting at the right moment”. So I put my Hero on the tripod and installed it on my window. The interval I used was the shortest one (I can’t remember but it probably was 0.5 or even 1 sec). So in fact every second or half it took a full-res photo. Then I just fell asleep while being tired of waiting and somehow managed to get up 4 hours after. I saw that my GoPro already discharged. After a few days I had time to look what I got. There was 450 or smth like that amount of photos. I scribbled through all of those and found THIS gem, was really happy that this was the first time in my life I captured lightning that big enough (thunderstorms are unfortunately pretty rare in my loc, last time before this there was thunder probably in 2013 last time, when I had no GoPro at all and all I was able to do is to take some “creepy” “white sky” photos and no lightning strikes”
