Flash Modes
The camera supports the following flash modes:
Flash modeDescription
Front- cur tain  sync This mode is recommended for most situations.
 In 
programmed auto and aperture-priority auto modes, 
shutter speed will automatically be set to values 
between 
1/250 and 1/60s (1/8000 to 1/60s when an optional 
flash unit is used with  Auto FP High-Speed Sync; 
0 329).
Red-eye 
reduction Red-eye reduction lamp lights for approximately one 
second before main flash.
 Pupils in subject’s eyes...

192
Rear-curtain sync In shutter-priority auto or manual 
exposure mode, flash fires just before the 
shutter closes.
 Use to create effect of a 
stream of light behind moving objects. In 
programmed auto and aperture-priority auto, slow 
rear-curtain sync is used to capture both subject and 
background.
 Use of tripod is recommended to 
prevent blurring caused by camera shake.
Flash off The flash does not fire.

The camera supports the following i-TTL flash control modes:
• i-TTL balanced fill-flash for digital SLR : Flash emits series of nearly invisible 
preflashes (monitor preflashes) immediately before main flash.
 Preflashes reflected from objects in all areas of frame are picked up by 
RGB sensor with approximately 91K (91,000) pixels and are analyzed 
in combination with range information from matrix metering system 
to adjust flash output for natural balance between main subject...

Flash compensation is used to alter flash output by from –3 EV to 
+1 EV in increments of 1/3EV, changing the brightness of the 
main subject relative to the background.
 Flash output can be 
increased to make the main subject appear brighter, or reduced 
to prevent unwanted highlights or reflections.
To choose a value for flash compensation, press the  M (Y ) 
button and rotate the sub-command dial until the desired value 
is displayed in the control panel.
 In general, choose positive
