Using E-TTL II and E-TTL Autoflash in the Shooting Modes
X
Select this mode when you want to set the shutter speed manually.
The camera will then automatically set the aperture matching the shutter
speed to obtain a standard exposure.
If the aperture display blinks, it means that the background exposure will
be underexposed or overexposed. Adjust the shutter speed until the
aperture display stops blinking.
W
Select this mode when you want to set the aperture manually.
The camera will then automatically set the shutter speed matching the
aperture to obtain a standard exposure.
If the background is dark, such as in a night scene, a slow sync speed will
be used to obtain a standard exposure of both the main subject and
background. Standard exposure of the main subject is obtained with the
flash, while a standard exposure of the background is obtained with a long
exposure using a slow shutter speed.
Since a slow shutter speed will be used for low-light scenes, using a
tripod is recommended.
If the shutter speed display blinks, it means that the background
exposure will be underexposed or overexposed. Adjust the aperture until
the shutter speed display stops blinking.
q
Select this mode if you want to set both the shutter speed and aperture
manually.
Standard exposure of the main subject is obtained with the flash. The
exposure of the background is obtained with the shutter speed and aperture
combination you set.
