A Flash Control
The following types of flash control are supported when a CPU lens is used in combination
with the built-in flash or optional SB-900, SB-800, SB-600, and SB-400 flash units (0 67, 172).
• i-TTL Balanced Fill-Flash for Digital SLR: Information from the 420-pixel RGB sensor is used to
adjust flash output for a natural balance between the main subject and the background.
• Standard i-TTL Fill-Flash for Digital SLR: Flash output is adjusted for the main subject; the
brightness of the background is not taken into account.
Recommended for shots in which
the main subject is emphasized at the expense of background details, or when exposure
compensation is used.
Standard i-TTL flash control is used with spot metering or when selected with the optional
flash unit.
i-TTL balanced fill-flash for digital SLR is used in all other cases.
