Just set the camera's shooting mode to
<Av>
(aperture-priority AE),
<Tv>
(shutter-priority AE), or
<M>
(manual) and you can use E-TTL II/E-TTL
autoflash.
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
Tv
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.

The camera will then automatically set the shutter speed matching the aperture to obtain
a standard exposure.
If the background
is
dark like 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
Av
main subject is obtained with the flash, while a standard exposure of the background is
obtained with a slow shutter speed.
e Since a slow shutter speed will be used for low-light scenes, using a tripod is
recommended.

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.

<DEP>
or <

be
the same as using the
<P>
(Program AE) mode.
