Here are two shots of our anniversary clock. The first was shot using a small MagLite flashlite focused to it's narrowist beam for illumination (the room was dark). The second used a laser rangefinder pointed at the pendulum for illumination. A laser rangefinder is basically a laser tape measure. It projects a "target--a circle with crosshair" on the object being measured and reports the distance from the instrument to the target.

In both of these photos, the clock pendulum was rotating normally. The lights were pointed at the pendulum. In the photo using the laser, you can see the reflection of the rotating pendulum in the base of the clock. (Actually, that's the nuclear reactor that powers the clock!).

Nikon D100, Sigma 28-70mm lens, tripod mounted, Aperture f8, shutter set to bulb and exposed for about a second. A remote cable release was used.

Cal, the second shot looks like a nuclear powered hour-glass figure!

Very interesting combination of techniques.

Aloha
