Using Your Document Camera
12
Glare
Glare can ruin a good picture. Glossy pictures
can reflect light from the ceiling lights in the
room - not the lights attached to the document
camera, but overhead fluorescent lights. Good
Examples of Bad Examples
13
Solutions

• Move the document camera
• Turn off overhead lights
• Wedgies!

Since it is not always convenient to move the
document camera or turn off the lights in the
room, wedgies are an ideal and simple answer.
14
Wedgies

• Use something to wedge under one side of the
  document camera to make the glare not reflect
  into the lens of the camera. The following are a
  few suggestions for wedges
• Block of wood
• Door stop
• Soda pop screw top
• Book
• What else can you think of using?

The Problem
The Solution
16
Tricking
Most document cameras have an auto iris feature
that can be useful. The auto iris looks at the
entire picture in the camera's field of view. It
tries to figure out what is the brightest part of
the picture. It will then adjust the iris or
close the iris to let less light into the
lens. The background of most document cameras is
white. When the upper lights are turned on, the
white background become blinding to the camera
lens. Therefore, the document camera closes the
iris down to allow in less light. However, not
only is the white background dimmer, but so is
the image you are trying to show. Since you now
know HOW the document camera works, you can work
to TRICK the document camera by placing a dark
background behind what you are trying to
showcase.
17
The Problem The Main Idea of this
picture is the remote control. However, the iris
of the camera has closed down so much you can
barely read the words on the buttons.
Some Solutions Using darker backgrounds of
different materials.

Zooming Since you know that the iris of the
camera will close and make your image or picture
dim, make sure you zoom in close enough to fill
the screen with the subject.
The Problem The main idea of what is under
the document camera is the photograph, not the
white background of the document camera.
The Solution By filling the screen with the
photograph, you do not have to worry about the
iris of the camera closing too much
