A very stormy weather stabilized over Warsaw in the beginning of June 2007. Almost every evening, a thunderstorm developed somewhere nearby. A particularly picturesque one on 9th June was actually preceded by a nice rainbow! Later, I took advantage of the storm proximity and elevation at 10th floor at my parent's apartment block. Here are some of the pictures. All were taken with Canon 20D, zoom lens set at 17mm, ISO = 100, T = 30s and A = f/11. Next day, the sky looked quite disturbed after the fireworks.
