This image was taken in during a thunderstorm in Toronto (Canada) during the summer of 2018! This storm definitely had better quantity and "quality" of lightning (if you can call it that), than usual! When it comes to lightning, the best technique I have found is to set up a shutter speed of roughly 4-8 seconds. This ensures that you don't have to worry about missing a bolt in between shots, as your "closed shutter time" is roughly 25-12 % respectively, of your total open shutter time. The downside to this is if the lightning is "weak" then it will be less significant in your shot. Weak lighting requires a faster shutter time. If you use a faster shutter time, you'll take more shots, but have greater chance of missing a bolt in between shots. Also, you will end up with way more "empties" to sort afterwards. I used an aperture of f/8 and an ISO 100 to balance out the exposure from the city lights. If anyone else uses a different technique, I'd love to learn about it!
