The Basics

A document camera is similar to an overhead projector however it allows you to show things in all three dimensions. So whether it is the overhead that you used in the past or something that a student brings in to share with the class you can easily share it with the rest of the group. Simply put it under the camera and turn it on.

Adjustments

There are only a few adjustments on a document camera that you have to worry about. Depending on the model that you have will determine the adjustments that you have.

Some of the basics are;

Auto white
One of the hardest things for a camera to figure out is what true white looks like. Turning this on or off will help
Light
Depending on the lighting in your classroom you may or may want to turn the light on to see certain details of an object.
On screen Iris
This is the size of the eye in the camera, if you increase it more light will be let into the camera.
Focus
This brings an object in and out of focus. Remember as you move the object the focus point will change.
Zoom
Do you want to focus in on the corner of a dollar bill use the zoom to do this.
Rotating the Camera
You can also move the head of the camera to change the orientation of the screen or the location that the camera is pointing at.
