After a barmy hot day in Prague (38° C/ 101° F), along came the inevitable lightning and downpour.  Luckily, my Canon 7D had miraculously risen from the dead so I was able to capture a few of the good lightning strikes over the Church of Mother of God before Týn.

The photos were taken with a stock Canon EFS 18-55mm at f5.6, ISO 100 for around 13″.
