I must admit that I have never been one to use a monopod. I use a tripod for landscape work, but for general photography I have never really used a monopod. Why? Well because I found that they actually caused problems with camera movement rather than solve it. I always found that the camera wavered around a bit and I felt that I could hold the camera steadier myself without any aid.
Well I now think that like a lot of things in photography if you use the right technique, then you will benefit from that growth in expertise. In the case of a monopod, then it is about setting it up properly.
The first thing to do is to make sure your tripod is sturdy enough. you will be extending it out, so you don’t want it to be too flimsy and bend. That defeats the object. Ensure you have a ball head on the top of the monopod, as you will need to angle your camera once you have set the monopod set up. The next stage is to ensure that we make the monopod as steady as a tripod. We do that by making a tripod using our own legs and the one leg of the monopod.
Place the monopod foot about four or five feet in front of you, so that when you tilt the head back to bring the camera to your eye, it forms a 45 degree angle with the ground. Note that you will have to increase its length by quite a bit to get the 45 degree tilt and still have it at eye level.

You now have a sturdy tripod created from the monopod and your own legs.
