Most people are familiar with tripods. They have three legs and are great for setting up at a location and taking photos from that one spot. Monopods, on the other hand, have only one leg, so they can be quickly moved from place to place.
But with only one leg, monopods aren’t very stable. This one has a spike at one end that can be pushed into the ground for timed photos. Or you can take fixed-height orbital photos, which is useful for projects like Print Your Head in 3D in which you take a series of photos, create a digital mesh online, and then print out your subject on a 3D printer.
