Flash Photography With An Ex- Series Speedllite - Canon EOS ELAN7E Instructions Manual

Flash Photography with an EX-Series Speedlite
With a Canon EX-Series Speedlite, flash photography is easy as using the
built-in flash. You can also use the advanced features below.
¢ This section applies when Speedlite 420EX is attached to the camera.
¢ E-TTL Autoflash
With E-TTL autoflash (preflash evaluative
metering), an optimum flash exposure is
obtained for the subject in focus. In the
aperture-priority AE mode, a slow sync
speed is set automatically in low-light
conditions to obtain a natural-looking,
balanced exposure between the subject
and background.
¢ High-Speed Sync (FP Flash)
High-speed sync (FP or focal-plane flash) enables flash synchronization
with all of the camera's shutter speeds from 30 sec. to 1/4000 sec.
¢ FE (Flash Exposure) Lock
FE lock obtains and locks the correct flash exposure for any part of the
subject. This is the flash equivalent of AE lock.
¢ Flash exposure compensation
Like normal exposure compensation, flash exposure compensation can
be used to set the flash output up to +2 stops in 1/2-stop increments.
¢ FEB (Flash Exposure Bracketing) (with 550EX or MR-14EX)
As with AEB (auto exposure bracketing), flash exposures can be
bracketed up to +3 stops in 1/2-stop increments.
¢ E-TTL wireless autoflash with multiple Speedlites
With a master Speedlite (550EX, ST-E2, or MR-14EX) and the 420EX set
as the slave unit(s), all the features listed above can be used for E-TTL
wireless autoflash. Since no connecting cords are required, flexible and
sophisticated lighting effects can be obtained.
El - E-TTL is an abbreviation for Evaluative-Through-The-Lens.
* With autofocus, the flash exposure is always based on the aperture, and E-TTL
autoflash metering is weighted at the active focusing point assumed to be
covering the main subject.
* When it is difficult to autofocus, the Speedlite's AF-assist beam is emitted
automatically.
