I was motorcycling through Ireland for a whole summer month, and I had rain every day. This day was quite nice, though, but after I put up my tent in the evening near Blackrock Bay there was a strange light coming from the sea. I went to the rocks at the water, placed the camera on my tripod and used a dark neutral density filter to have a long exposure time, making it able to watch the oncoming clouds that quickly became a thunderstorm.
