Summer Lightning.  Close but no cigar!  I shot this one out my bedroom window.  Since a rangefinder trips the shutter 10 times faster than an SLR, I gave it an experiment in catching a lightning bolt.  I got the shot shown here, but the lamp post was in the way.   I braced the camera on a beanbag on the windowsill.   Shutter speed was around 15th of a second, aperture wide open.  Leica M6 and Summicron 35mm F2.  Film--Velvia.
