1.5 Checking and Adjusting the AE, E-TTL, and Exposure
Checking the Exposure Level
If the EOS D60's camera metering sensor (SPC) output and the shutter
adjustment are correct, the camera will obtain correct exposure. And if the digital
section's ISO setting is adjusted correctly, the digital section should obtain the
correct exposure. If the user wants the exposure level to be increased or
decreased, check the total exposure level, then refer to it when making the
exposure level adjustment with the camera.
To check the total exposure level, you will need the adjustment software or an
image-editing program like Photoshop. The procedure using the adjustment
software is explained below.
* This procedure is for checking if the exposure level is correct as it would be with
film in a film-based camera.
Total Check
1) Connect the camera and start up the digital adjustment software.
2) Select "
Test shooting "
3) Set the camera settings as follows. Take pictures while changing the ISO speed
and shutter speed.
Camera settings
•
Camera mode: Aperture-priority AE
•
Aperture: f/8.0 (f/5.6 is acceptable)
•
Shutter speed: Auto
•
ISO: All ISO speeds
•
White balance: Tungsten
•
Image size: JPEG, L size
4) Press the shutter button.
5) The image will be captured. Drag (select) the mouse at the center of the image.
6) The image's RGB and YCrCb will be displayed. Check that the RGB's G value is
120 count +/-10 count. This 120 ount is the same at all ISO speeds. If you use
an image-editing program like Photoshop, do the same as above by selecting
the image center to display the RGB outputs. If the G value is the same, it is
okay.
Part 4: Electrical Adjustments
4-7
The light source (EF8000, 5000) must be maintained as indicated
in "Light Source Maintenance." It must produce the correct
brightness (LV 9 = 64cd/m2) especially if you will check the
exposure level.
The user may request that the exposure level be increased or
decreased. In such a case, first check the exposure level and do the
adjustment with the camera.
