Flash Photography - Canon EOS-1DS Mark III Instruction Manual

Flash Photography
Using an EX_series $peedtite
An EX=series Speedlite (sold separately) makes flash photography as
easy as normal shooting without flash. You can easily do the flash
operations below. For detailed instructions, see the EX=senes
Speedlite's instruction manual.
• E-TTL II Autoflash
E-TTL II is an autoflash exposure system incorporating improved
flash exposure control and lens focusing distance information,
making it more precise than the previous E-TTL system (evaluative
flash metering with preflash). The camera can execute E-TTL II
autoflash with any EX=senes Speedlite.
High-Speed Sync (FP flash)
With high=speed sync, you can set a flash sync speed faster than 1/
250 sec.
, FE (Flash Exposure) Lock
Press the camera's
<FEL>
button to lock the flash exposure at the
desired part of the subject.
Flash Exposure Compensation
In the same way as normal exposure compensation, you can set
exposure compensation for flash. You can set the flash exposure
compensation up to +3 stops in 1!3=stop increments.
With the camera, set it by pressing <_o_> and turning the <O> dial
, FEB (Flash Exposure Bracketing)
The flash output is changed automatically for three successive shots
(only with FEB=compatible Speedlites). Set flash exposure
bracketing up to _+3stops in 1/3=stop increments. During FEB
shooting, the <$_> icon will blink in the viewfinder.
, E=TTL II Wireless Autoflash with Multiple Speedlites
As with wired, muWple Speedlites, wireless E-TTL II autoflash with
multiple Speedlites (those compatible with wireless flash) provides
all the above features. SopMsticated lighting effects can be obtained
since connection cables are unnecessary.
