Here is a exposure made at night using the Rolleiflex Automat (75mm F3.5). It was fun to make this, no light meter, guessing the exposure and counting 1-1 thousand, 2-1 thousand. I did 30 to 60 secs at f22 on Tri-x and used a small carbon fibre tripod. Dead of night photos. Very basic and fun photography. Made me want to do the "Edmonton at Night" series I thought of years ago.
