Spiral traces of light - 2

In these photographs the spiral trace of light is obtained by a pendulum with a tinny source of light. The camera is set on a long time exposure.


Two months later I continue experimenting with pendulums, this time with a tinny flickering flashlight. The flicker seams to be very precise and I like the curved pattern obtained with the short lines that the light source creates.


The next shot took 3.5 minutes. I show here only a detail of the complete frame.


In any case, and because it was fun, I continued experimenting with the continuous flashlight as well.
