Preparing to photograph a lunar eclipse requires much more knowledge and research efforts than preparing to watch a moon eclipse. When you decide to watch a moon eclipse, basically what you need to do is just going outside at looking for the moon in the sky.

Photographing a lunar eclipse, however, requires much more detailed knowledge on the direction, altitude and time of every phases during the moon eclipse. You need to plan ahead, pick a location, set up your camera, pointing your camera to the correction direction and wait for it to happen. Besides, you need to carefully set up a timer and adjust your camera exposure (ISO speed, shutter speed and aperture) during the entire moon eclipse. If you want to photograph the whole period of lunar eclipse, you may have to continue photographing for at least 4 hours, which may be an extreme task especially in winter season.

2000 Total Eclipse Over Maui 
The Multiple Exposure technique was used during the total lunar eclipse of 2000 July 16 from Maui. A Nikon 8008 in multiple exposure mode was used to capture the entire eclipse on one frame of film. 
The basic exposure of 1/125 second at f/5.6 was increased to 1/8 second within 15 minutes of totality and then set to 4 seconds throughout totality. A second exposure (metered) captures morning twilight and silhouetted palm trees.
