I set up the camera (XE1) with the XF23mm to provide a semi wide view of the environment on my tripod. I set the camera on 'B' or BULB and used the Triggertrap app (and dongle) on my iPhone to trigger the shutter. I used apertures of between f8 and f4. Exposure time was a bit of a guessing game and varied with the number of lighting strikes at any given time. Successful captures ranged between 30 seconds and three minutes exposure time at ISO 200 .
After half an hour or so the storm front dispersed so I went home, again we escaped any severe weather but we did get some much needed rainfall - 6mm collected in our rain gauge overnight.
