Thanks for directing me to this post from your other one. You wrote a very detailed post about the technique. Well done! I used to do a lot of long exposure shots back in the day when I was using a 4x5 large format camera. Everything was totally manual of course back then. A couple of years ago when I was back in Scotland I went chasing The Northern Lights, but only had a flimsy tripod. I didn’t think I had captured anything, because all I saw was a faint glow in the sky, but when going through a file from that year a couple of weeks ago and processing it in Adobe Raw, I was amazed to see that there was something there! Not enough to be a spectacular Northern Lights shot , but still maybe something I could write a post about!
