The SB-500 has 2 flash control modes—manual flash control and i-TTL
flash control.
Flash control modes cannot be selected on the SB-500. The setting
of the camera on which the SB-500 is mounted automatically
applies.
i-TTL Flash Control
Information obtained by monitor pre-flashes and exposure control
information is integrated by the camera to automatically adjust flash
output levels.
• To take pictures using the SB-500 set in i-TTL flash control, see
“Basic Operations.” (0B-9)
• Either the i-TTL balanced fill-flash or the standard i-TTL flash option
is available depending on the camera settings. i-TTL flash control
options cannot be selected on the SB-500.
i-TTL balanced fill-flash
The flash output level is automatically adjusted for well-balanced
exposure of the main subject and background.
Standard i-TTL flash
The main subject is correctly exposed regardless of background
brightness. This is useful when you want to highlight the main subject.
