3 Setting Speedlite FunctionsN
Shutter synchronization
Normally, set this to [First-curtain synchronization] so that the
flash fires immediately after the exposure starts.
If [Second-curtain synchronization] is set, the flash will fire right
before the shutter closes. When this is combined with a slow shutter
speed, you can create a trail of light such as from car headlights at
night. With 2nd curtain synchronization, two flashes will be fired:
Once when you press the shutter button completely, and once
immediately before the exposure ends. Also, with shutter speeds
faster than 1/30 sec., 1st curtain synchronization will automatically
take effect.
You can also select [High-speed synchronization] (e). For
details, refer to the Speedlite’s instruction manual.
Wireless functions
Wireless flash shooting with multiple Speedlites is possible with
optical or radio transmissions. For details, see the wireless
Speedlite’s instruction manual (for Speedlite 90EX, etc.).
Flash exposure compensation
See “Flash Exposure Compensation” on page 154.
Flash mode
You can select the flash mode to suit your desired flash shooting.
[E-TTL II flash metering] is the
standard mode of EX-series
Speedlites for automatic flash
shooting.
[Manual flash] is for advanced users
who want to set the [Flash output
level] (1/1 to 1/128) themselves.
Regarding other flash modes, refer to
your Speedlite’s instruction manual.
