Flash With Shutter Speed-Priority Ae - Canon SPEEDLITE 220EX Instructions Manual

Flash with Other Modes

2) Flash with Shutter Speed-Priority AE

When you want to control the
shutter speed to create a special
effect, use shutter speed-priority
AE. Set the desired sync speed
anywhere from 30 sec. up to the
camera maximum sync speed.
The camera sets the aperture
automatically to suit the back-
ground light level. The E-TTL
autoflash control system regu-
lates the flash output according
to the shutter speed you set for
optimum flash exposure.
The aperture value blinks in the viewfinder to alert you of a possible over-
exposed or underexposed background. Change the sync speed until the
aperture value stops blinking and remains displayed.
