Flash Shot With Speedlite 550Ex - Canon EOS 10D Digital Instruction Manual

Flash Shot with Speedlite 550EX

With Speedlite 550EX, flash shooting is as easy as any AE mode, and you can use the
following features:
●E-TTL autoflash
With E-TTL autoflash (preflash evaluative metering),
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 situations 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 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 exposure lock 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)
●
As with AEB (autoexposure bracketing), flash exposures can be bracketed up to +/–3 stops
in 1/2-stop increments.
● E-TTL wireless autoflash with multiple Speedlites
E-TTL autoflash can also be implemented with multiple wireless Speedlites. All the features
listed above can be used, and no connections codes are required. Sophisticated lighting
effects can be obtained as easily as using a Speedlite directly attached to the camera.
•
In difficult focusing conditions, the AF-assist beam is emitted from the 550EX
Speedlite, and automatically linked to the active AF point
•
With an external, EOS-dedicated Speedlite, the camera will be a Type-A camera
(compatible with E-TTL autoflash).
