I stepped outside of my house last weekend to an amazing sunset during a thunderstorm. I grabbed my gear and ran up on a hill (most of the lightning was in the distance), set my camera on a tripod and focused on the storm just as it started raining on me. I quickly set my shutter speed to 1/3 of a second so as to increase my chances of catching lightning and set my intervalometer to take a shot every second
I spent the next 3 minutes holding my shirt over my camera to protect it from the rain. I think it was worth it.
