Flash Photography - Canon EOS 1D Instruction Manual

Flash Photography

EX-series Speedlite
An EX-series Speedlite (optional) makes flash photography as easy as
normal shooting without flash. You can easily do the flash operations
below. For detailed instructions, see the EX-series 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-series Speedlite.
• High-Speed Sync (FP flash)
With high-speed sync, you can set a flash sync speed faster than 1/
300 sec.
• FE (Flash Exposure) Lock
Press the camera's <I> 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 with the <Q> button and <5> 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 ±3 stops in 1/3-stop increments. During FEB
shooting, the <r> icon will blink in the viewfinder.
• E-TTL II Wireless Autoflash with Multiple Speedlites
As with wired, multiple Speedlites, wireless E-TTL II autoflash with
multiple Speedlites (those compatible with wireless flash) provides
all the above features. Sophisticated lighting effects can be obtained
since connection cables are unnecessary.
