Flash Photography with an EX-Series Speedlite
Q • About automatic reduction of flash output
If an EOS-dedicated Speedlite is used for a subject backlit by an overhead
light, the flash output is reduced automatically to avoid having an unnatural¬
looking exposure. This is called automatic reduction of flash output.
• In the Basic Zone modes, flash photography is as easy as with the built-in
flash.
• Using the <
DEP
> mode with flash gives the same result as the <
P
> mode.
High-Speed Sync (FP Flash)
When Speedlite 420EX is set to the high-speed sync mode <^h>, it can
synchronize at all shutter speeds, even those faster than 1/125 sec. When
high-speed sync is enabled, <^h> is displayed in the viewfinder.
High-speed sync is useful in the cases listed below.
• High-speed sync works in Creative Zone modes.
(1) When you want to use fill flash for a portrait and maintain background
blur with a large aperture.
(2) When you want to create a catchlight in the subject's eyes.
(3) When you want to use fill flash to eliminate shadows.
