3Refocus the subject, change the
composition as desired, and take
the picture.
•When you change the scene composi-
tion, the difference between the locked
exposure value and the continuously
metered exposure value is displayed
in the viewfinder in real-time.    
This custom function lets you lock the
exposure with the shutter button instead
of the AE lock button ( ). Pressing the
AE lock button activates autofocusing.     
• When using One-shot AF together with Evaluative metering, the exposure r\
eading is
automatically locked when autofocusing is completed after pressing the s\
hutter button
halfway.
• When using One-shot AF together with Fine Spot or Partial metering, expo\
sure setting
is locked  onlyduring continuous shooting.

(Refer to pages 84–85)
If you use AE lock to register a shadow read-
ing of your subject and then change the
scene composition to read a highlight area (or
vice versa), you can then use exposure com-
pensation (refer to page 42) to adjust the
exposure level based on the brightness range
of the scene.

7. Exposure Compensation
When taking pictures in an AE shooting mode, you can compensate the
exposure according to the subject conditions either by using the quick
control dial while looking through the viewfinder or by using the exposu\
re
compensation button and the main dial. Exposure can be compensated
up to ±3 stops in 1/3-stop increments.     
●
Using the Quick Control Dial
1Set the quick control dial switch to.
2Focus the subject and confirm the
exposure.
3Turn the quick control dial to set the
desired exposure compensation
amount.
•The quick control dial is active only
when the shutter button is half pressed
or while the six-second timer is operat-
ing.      
AL
In addition to 1/3-stop increments, the
exposure compensation amount can also
be input in 1/2-stop increments.    Custom Function 
(Refer to pages 86–87)

Exposure Compensation
•The exposure level indicator and expo-
sure compensation symbol are dis-
played in the viewfinder, and the com-
pensation amount is displayed in the
LCD panel’s exposure level indicator.
• In the LCD panel, “+” indicates overex-
posure and “–” indicates underexpo-
sure relative to the camera’s meter
reading.
• In the viewfinder display, overexpo-
sure and underexposure are indicated
respectively by exposure compensa-
tion amounts above and below the tri-
angle index at the center of the scale.
•
After setting the desired compensation
amount, it is recommended to set the
quick control dial switch to to pre-
vent accidental alteration of the setting.
• To cancel the exposure compensation,
operate the quick control dial to return
the exposure level indicator to the zero
()  position.    
1Indicates correct exposure
2 Indicates more than 3 stops overex-
posure
3 Indicates more than 3 stops underex-
posure
If CF No. 6 is used to set the exposure compensation amount in 1/2-stop \
or 1/3-stop incre-
ments, the exposure level indicator in the viewfinder display and in the\
 LCD panel appear
as shown below.

●Using the Exposure Compensation Button
Exposure compensation can also be carried out using the exposure com-
pensation button ( ) together with the main dial.   
1Focus the subject and confirm the
exposure.
2Press and release the exposure
compensation button, then turn the
main dial (while the six-second timer
is activated) to set the desired expo-
sure compensation amount.

8. Auto Exposure Bracketing [AEB]
Use auto exposure bracketing to take a sequence of pictures at different\
exposures. When this function is set, the camera automatically takes
three exposures in sequence while shifting the exposure for each picture\
.
The bracketing amount can be set in 1/3-stop increments up to ±3 stops
from the metered exposure value. When the shutter button is pressed,
three frames are exposed according to the current film winding mode
(refer to “2. Changing the Film Winding Mode” on page 67), in th\
e
sequence: underexposure  →correct (metered) exposure  →overexpo-
sure.
Auto exposure bracketing is particularly effective when using slide film\
,
which produces noticeably different results with even small exposure var\
i-
ations.       
The shooting sequence can be changed
to: correct (metered) exposure  →under-
exposure  →overexposure. This function
also lets you set the AEB step amount by
simultaneously pressing the AF mode
and shooting mode selectors while turn-
ing the main dial.      The AEB step amount can also be input
in 1/2-stop increments.   
Underexposure (–1/3)Correct (metered) exposure (0)Overexposure (+1/3)
Custom Function 
(Refer to pages 86–87)
Custom Function 
(Refer to pages 88–89)
If auto exposure bracketing is used with custom function F-12 set to mir\
ror-up mode, the
camera will operate in single exposure mode regardless of the current fi\
lm winding mode
(single exposure, continuous exposure).

Auto Exposure Bracketing [AEB]
1Open the palm door and simultane-
ously press the battery check button
and film winding mode selector.
• AEB appears in the LCD panel.     
• The display remains for six seconds
after you release the buttons.
2Turn the main dial to set the desired
bracketing amount.
•The set bracketing amount is shown in
the LCD panel as both a graphic level
display and a numerical value. The
diagram shows the case when setting
a bracketing amount of  ±1-1/3 stops. 
3When you press the shutter halfway
and then remove your finger, the
bracketing amount is displayed by
the viewfinder’s exposure level indi-
cator.
4Take pictures according to the cur-
rent film winding mode.
• The compensated exposure value for
each shot is displayed in the LCD
panel as the three frames are
exposed, and the  AEBindicator ( )
blinks continuously until all three expo-
sures are completed.

•By setting exposure compensation (see “7. Exposure Compensation” \
on page 42) after setting
the auto exposure bracketing step amount, you can take three sequential \
overexposed or under-
exposed shots while varying the compensation for each shot. The bracketi\
ng step amount is not
changed even when shifting the standard (metered) exposure.
• Auto exposure bracketing cannot be used in bulb mode or when using flash\
.
• Auto exposure bracketing cannot be set on the EOS-1 N RS in RS mode.
Auto Exposure Bracketing [AEB]
• The compensation amount for each
shot is also displayed in the viewfinder
by the exposure level indicator.
• It is possible to take one shot at a time
even in continuous exposure mode.
The AEB indicator ( ) blinks contin-
uously until all three exposures are
completed.
•
If the shutter is held completely
pressed in continuous exposure mode,
three frames are exposed in sequence
but the viewfinder’s metering level indi-
cator is not active. Film winding auto-
matically stops after three frames.
• When AEB is used in conjunction with
the self-timer, three frames are auto-
matically exposed in sequence after a
2- or 10-second delay.
5To cancel auto exposure bracketing,
repeat steps 1 and 2 to reset the
bracketing amount to 0.
•Auto exposure bracketing is also can-
celed when the lens is exchanged, the
film is replaced or rewound, bulb
exposure mode is set, flash charge
completion is loaded, the clear button
is pressed, or the main switch is set to
“ ”.

							•When the number for the maximum aperture of the lens blinks in the displ\
ay, the image
will be underexposed. Turn the main dial to a slower shutter speed so th\

play stops blinking.
• When the number for the minimum aperture of the lens blinks in the displ\
ay, the image
will be overexposed. Turn the main dial to a faster shutter speed so the\
 aperture dis-
play stops blinking.
