during the last days the weather was really bad as there was a bad tempest in the evening.
Some days ago when I visited my family in Franconia I took my timer for my SLR with me which allows me to extend the exposure time to more than 30 seconds. So, when I noticed the clouds coming, I prepared my camera with the tripod on the balcony, adjusted the focus (which has to be done manually in this case) and waited for the first flashes. At first I had to perform a series of test shots to find some good settings, but afterwards the results where quite good for the first shots.
Have a wonderful time!
