Any time a camcorder is handheld there is a likelihood of camera shake occurring due to unintentional hand movement or shakiness. One of the best ways to eliminate this problem is to use a tripod whenever possible. However, the situations in which it is unhandy to use a tripod, or one is not available, are too numerous to mention. Thus, the average user typically operates without a tripod with the result being tremulous or jerky films.

Thankfully, camcorder manufacturers offer a variety of methods to reduce the effect of inadvertent movements. The two most common features offered on current camcorders are electronic and optical image stabilization. Electronic stabilization, also termed digital stabilization, is the more economical means of steadying images. However, optical stabilization, or mechanical stabilization as it is also described, tends to offer superior performance. There are also other differences between these two methods of image stabilization that potential buyers should consider before making a purchase.

In order to "stabilize" an image, the camcorder must first "sense" the movement, differentiate it from intended movement of the camera, and then compensate for image changes due to unintended movement.

With electronic stabilization, the image on the CCD is compared from frame to frame. If the image moves from one frame to the next, the camcorder will stabilize the image by eliminating the portions of the image around the outer edge; the portion which varies from one frame to the next. Once this portion of the image is eliminated it is filled in by digitally expanding the center portion of the image. When a portion of the image is eliminated and the remaining pixels are left to fill in the area, the quality of the resulting image is often compromised. Because the digital zoom function used on many camcorders has a similar effect of reducing image resolution, it should never be used in conjunction with electronic stabilization.

A camcorder with electronic stabilization should be able to differentiate the movement of a subject, say a bicyclist riding across the field of view, versus the movement of an entire image or scene caused by shakiness. However, it is still best to disable image stabilization whenever panning to capture intended movement to assure that the camcorder does not attempt to stabilize such motion.

Electronic stabilization works best outdoors and in situations where lighting is very good. Because electronic stabilization adds no additional moving parts, camcorders with this type of feature tend to be smaller and lighter weight that camcorders which employ optical stabilization.

Camcorders with optical image stabilization sense movement via built-in gyrosensors which detect motion and signal adjustments to the camcorder lens which redirect incoming light to counteract small movements. This is a more complex process but does not result in the loss of image resolution as all image information is retained. Optical stabilization is thus more effective in low-light situations and when zoom is used. In addition, the optical stabilization method seldom results in false interpretation of intended versus unintended movements. On the other hand, with a more complex lens and additional moving parts, camcorders which employ optical stabilization tend to be larger and consume more power than their electronically oriented counterparts.

Image stabilization is an important feature for some buyers who wish to produce films that are smoother and absent of much of the jerkiness present in handheld shots. The difference between electronic and optical stabilization however, can be significant. Thus knowing which type of stabilization is present on any camcorder being considered for purchase is critical.

Zen masters will tell you that the most effective way of communicating is to perform direct pointing.

This morning, for example, my 5-month old and I were strolling through the house on one of our art tours, something we do regularly between 4 and 5.

We pause at painting after painting, and I recite the names of colors and point to them.

For the past two days I have paused at different works and asked, Can you show me the red?

Without hesitation she lifted her arm and touched the matching oil on canvas.

Mind you, apart from recognizing her name, this is the first time she has so specifically attached a meaning to a word.

Communication simply cannot get clearer than this.

The underlying paintings are abstract, but our exchange of ideas here is perfectly concrete.

Linguists tell us that as we climb the ladder of abstraction, the potential for misunderstanding increases exponentially. To avoid miscuing other people and making typical errors of interpretation, we should strive for concreteness.

We would say, for instance, Throw me the ball, please, and not Throw me the spherical object over there.

When we engage in communications with clients, we should also be crystal clear, especially in signaling three things:

(1) Our initial willingness and ability to help;

(2) Our belief that we have been of great help, and that we desire to help even more; and

(3) Our appreciation for their business.

I crafted a conversational path to make these three clear points. It says, for example, after we have heard a clients request, Sure, Ill be happy to help you with that.

Note how definitive, how conclusive, and how optimistic and self-confident that phrase sounds.

Let me share with you how some of my trainees will distort it, often unconsciously.

Theyll substitute, Okay for Sure, thinking the terms are synonymous.

Thats like saying pink is the same as red.

Pink may have been red, with white added to it, but pink is not a primary color; it is a DILUTION of red. It has its place but it doesnt send the same message as a bold red.

Okay is a similar dilution. It says Im kind-of ready, willing and able to help you.

Why would we willingly signal insecurity instead of security; reluctance instead of eagerness, pessimism instead of optimism, and inability instead of ability?

Peter F. Drucker, world class management guru and my MBA advisor, offered an ultra-basic definition of a leader. He said it is a person who attracts followers.

We want and need clients, and in order to attract, satisfy, and to keep them, to add them to our following, we need to show leadership behaviors.

A good place to start is by using more concreteness in our communications, and to intentionally remove wishy-washy abstractions.

Direct pointing is more than an ideal. It is a most practical way to build your business.
