21Simply set the camera’s shooting mode to <X> (shutter-priority AE),<W> (aperture-priority AE), or <q> (manual exposure) and you canuse E-TTL II/E-TTL autoflash suitable for each shooting mode. If you use the <Z> or <Y> shooting mode, the result will be the same asusing the <V> (Program AE) mode. 1/X sec. is the camera’s maximum flash sync speed.E-TTL II/E-TTL Autoflash by Shooting ModeXSelect this mode when you want to set the shutter speed manually.The camera will then automatically set the aperture matching theshutter speed to obtain a standard exposure based on the metering ofthe camera. If the aperture display blinks, it means that the backgroundexposure will be underexposed or overexposed. Adjust the shutterspeed until the aperture display stops blinking.WSelect this mode when you want to set the aperture manually.The camera will then automatically set the shutter speed, matching theaperture to obtain a standard exposure based on the metering of the camera.If the scene is dark, a slow sync speed will be used to obtain astandard exposure for both the main subject and background.Standard exposure of the main subject is obtained with the flash light,while a standard exposure of the background is obtained with a longexposure using a slow shutter speed. Since a slow shutter speed will be used for low-light scenes, using atripod is recommended. If the shutter speed display blinks, it means that the backgroundexposure will be underexposed or overexposed.
