Free hand shots (forgot the tripod). Two things to my advantage: build-in image stabiliser (Canon) and breathing technique I learned once with riffle shooting.
Blur South Africans experience every now and than a load shedding. No street lights but only the lights of movement in the street. The first picture (exposure time 1/4 sec) shows a car that did not stop for a STOP-sign; probably the driver did not see it with the obvious excuse of load shedding. The second (1 sec exposure) shows two cars just before a frontal crash (no injuries BTW); the fast moving one also did not see (seemingly) a STOP-sign. The third one (4 seconds with camera holding against a wall) shows the rear light of a taxibus hobbling through a dip in a gravel road.
