Measurement procedure
1) Attach a normal EF 50mm f/1.8 lens to the known-good camera and connect
the camera to the computer. Start up the digital section adjustment software.
2) Select "Color matrix adjustment."
3) Select "White balance setting", adjust the white balance to the color viewer. Put
the camera close to the color viewer and press "Release." By releasing, the
white balance
will be memorized.
4) Select "Color setting"
5) Set the camera as follows(It will be set automatically):
•
Shooting mode: Aperture-priority AE

5) Place the color bar chart on the color viewer, and adjust so that the chart is
correctly positioned. For details, see the adjustment screen. After
everything is set, click "Cancel."
6) Select "Image evaluation," and click "Release." When you click "Release," the
image will appear. Select the center of each color.
7) Put the cursor over the graph's point, and right-click the mouse to select "Set."
That point will then be saved. Repeat this step for all seven color bars.
*If the "Y" level is not 178±10 counts, adjust the exposure setting.
If you selected "Set" by mistake, right-click the mouse and select "Clear."
The points you set will become the color bar chart's characteristics. This point-
matching adjustment will be done later.

level of the white on the color bar is 178±10 counts during
measurement.
