The same guidelines apply. Avoid moving the zoom lens in and out. Zooming loses its impact when you repeat it for no creative purpose. Most of the time, it's best to use the zoom control just to change the focal length between shots. Get people shots, lots of them.
Nothing is as interesting to watch as other people.
Videotape your companions, but encourage them to do something other than wave at the lens. And to make sure you can get in the picture from time to time, show a traveling companion how to operate your camcorder. Record comments about a place while you are shooting a travelogue. You or someone else can do the talking, or, even better, stand close to your tour guide and record his or her commentary. Not only will it make the tape more interesting, it will also jog your memory when you get home.
