For the past week or so we've been treated to late afternoon and evening thunderstorms with dramatic cloud formations often accompanied by lightning strikes. Last night we had a dry storm with lightning. I set up my X-Pro2 on a tripod to try to capture some of the strikes. With an aperture of f/11 and ISO 200 (This is when I wish Fuji had a lower 100 as the base ISO.) I ended up with a shutter speed of 4 seconds. When photographing lightning you need to keep snapping away with a slow shutter speed. In this case, I was using a 4 second exposure. I usually time my exposures by waiting several seconds after a strike and then opening the shutter for a time exposure. Then you've got to be lucky.
