A monopod will also reduce the fatigue you may experience when holding a heavy camera or using heavy lenses. Fatigue in such situations can be significantly reduced with a monopod, especially when you have long periods of time in between each shot. You may need to purchase a tripod mount ring to attach your monopod to your lens if your monopod didn't come with one. Monopods can be set up a monopod with a few simple motions. If you are photographing a fast-moving sporting event or want to observe wild animals that will be frightened away by too much noise or movement, a monopod will give you an advantage over a tripod. This is especially true when you're photographing on slanted grounds, because a tripod's legs will need to be readjusted every time you move. You will have more freedom with aperture and shutter speed if you steady your camera with a monopod, as opposed to just holding it. A tripod, which keeps the camera completely still, is still the best method of taking photographs in these conditions. The biggest benefit of a monopod over a tripod in these such conditions is its ease of use and portability. Bring a monopod instead of a tripod when you know you will be working in crowded conditions. Monopods require far less width than tripods. Set the timer on your camera, and then hold the monopod with two hands and raise it up. In situations when you want to get a shot from a higher position, such as a dance floor, a large crowd, or a bird nest, this can be an effective way to do so.

Summary:
Mount your camera lens on a monopod to lessen shake when using a long lens. Use a monopod when you don't have time to set up a tripod. Take low-light photographs using a monopod. Use a monopod in crowded situations. Use the monopod as a reach extender for high up shots.
