OK, you people remind me of the time I was going to beat up the school bully. I had quite a fan club behind me that day but fell flat on my butt with that effort as well!
Brandon, Khogan, Eric F, Soumya, et. all; Don Ellis has a great method that also works well when a fast getaway is not an issue. With me, the exit is ALWAYS the main issue.8)
The traditional tripod has nothing to do with your body. You can breath, scratch, frown, and flow blood to your heart's content without involving the camera in most circumstances. The monopod, however, must by design become a part of your body and only practice will determine the maximum gain in stops you can achieve.
Let's step through the three points:
As with Don's method, the most important part of the monopod is the foot. We will have three points, but the foot will be the most stable. Mount your camera, extend the monopod, and step on the "foot" with your right shoe. You can reverse this to the left if you want after the illustration. Assume a comfortable stance, six inches between your feet, toes pointed forward (important), with the knees very slightly bent. You have point one under your right foot.
Place your elbows against your ribs (lightly) as you grip the camera on both sides keeping the camera vertical with your subject. Some people even feel better with the thumb of one hand pressed lightly against a cheekbone for additional stability. This is point two.
Point three will determine your ultimate success and will require the most "feel". Move your left foot slightly forward, three or four inches, and press your left knee to the right against the vertical beam of the monopod. By having the toes straight forward, you will notice the left knee is already pointed slightly toward the right and will make ready contact with the beam. You can vary the pressure you apply with your left knee against the beam to give the most stable feel to your hands. Avoid using your hands to apply pressure against your left knee. Your hands should already be locked in place on the camera with the determination not to move. The only variable part of this "body tripod" should be your left knee against the vertical beam of the monopod, pressing toward the right. You will know when the amount of pressure feels right for you.
This will, as I said, take a little practice. If done correctly, you should feel very good even right at first. Don't be discouraged by normal body sway and the effects of breathing. You will quickly learn to control these as you practice. I have found that it is better to compose and focus, etc., before you apply the left knee pressure. The less time spent in the actual firing position, the better due to natural fatigue caused by an un-natural body position.
The ideal situation for the monopod is the example in Don's post. The photographer can brace against the table in this photo and have two very stable points; the foot at the bottom and the table in the center of the beam. Just remember that the monopod, like the tripod, must have three points.
I hope this will help even though it is long winded. Verbal pictures are all I had tonight as the professional model went to bed early.:O
