Lightning could be the most unpredictable photo subject. There are a number of ways on how to successfully capture them…for now let’s focus on long shutter times. It’s impossible to click immediately once you see a flash in the sky…There are those remote controls that senses flash…but I don’t have that nor do I have the money to buy one. so the best way is to use a slow shutter speed around 20-30 seconds with an aperture of f/2.8 – f/22 at ISO 100. 🙂
