Set the camera's shooting mode to <
Tv> (shutter-priority AE), <
Av> (aperture-priority AE), <
Fv> (flexible-priority AE), or <
M> (manual exposure) to use E-TTL II/E-TTL autoflash for that mode.
Tv |
Enables you to set the shutter speed manually. Based on your shutter speed, the camera sets an aperture to provide standard exposure.
- If the aperture value blinks, adjust the shutter speed until it stops blinking.
|
Av |
Enables you to set the aperture manually. Based on your aperture, the camera sets an shutter speed to provide standard exposure.
- If the shutter speed blinks, adjust the aperture until it stops blinking.
|
Fv |
Enables you to set the shutter speed or aperture manually.
- If the aperture value blinks when you set a shutter speed, adjust the shutter speed until it stops blinking.
- If the shutter speed blinks when you set an aperture, adjust the aperture until it stops blinking.
|
M |
Enables you to set both the shutter speed and aperture manually. Light from the flash provides standard exposure for the main subject, but exposure for the background varies depending on your specified shutter speed and aperture. |
NOTE: If you use the <DEP> or <A-DEP> shooting mode, the result will be the same as using the <P> (Program AE) mode. |
