Canon EOS 10D instruction manual Flash Shot with Speedlite 550EX, High-Speed Sync FP Flash

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).
