POTD: Clockworks #4

Clockworks #4
Lewistown, Montana

This gear and arm was almost constantly in motion, making it challenging to get a photo of it that was not blurred due to the shutter speed required to get a properly exposed image in the dim light of the clock tower. Fortunately they paused momentarily when the arm was at it apex, giving me just enough time to get the job done. (For the geek inclined camera buffs out there, I used a shutter speed of 1/8s and an ISO speed of 12,800. I must admit that the shutter speed was also limited by my refusing to shoot with a tripod in most situations. Thank goodness for image stabilization and a reasonably steady hand!)
