Canon Speedlite 420EX - Manual (Page 32)

Flash in Full Auto Mode aesaumaiìaiaiu^^
With the 420EX attached to a Type-B camera set to <P> (Program AE),
flash photography will be fully automatic and as easy as normal AE
photography without flash. The camera sets the shutter speed and aperture
automatically to suit the lighting situation, whether it is dark or daylight (fill
flash). TTL autoflash thereby sets the flash exposure automatically.

Take the picture.
• Check that the <'/> icon is lit in the
viewfinder, then take the picture.
Check that the flash exposure
confirmation lamp lights.
• When a correct flash exposure has
been obtained, the lamp lights for
about 3 sec.
If it does not light, underexposure
may have occurred. Check that the
<PILOT> is lit, then move closer to
the subject and take the picture
again.
