ADI, pre-flash TTL, and manual flash control are available. Flash
control is changed in section 2 of the recording menu (p. 64). The
flash control used depends on the lens and flash combination.
ADI (Advanced Distance Integration) flash metering - combines
distance information from D-series lenses with information from a
pre-flash exposure. ADI metering is less influenced by subject
reflectance.
The camera automatically switches from ADI metering to pre-flash
TTL when the autofocus system is prevented from focusing. When using the Macro Twin Flash
2400, Marco Ring flash 1200 or a wireless or off-camera flash unit, flash control is set to pre-flash
TTL.
When using the Program Flash 2500(D), switch both the flash unit and camera to ADI metering.
Pre-flash TTL - calculates flash exposure with a pre-flash only. This mode must be used with
close-up filters or filters that reduce the amount of light entering the camera such as neutral density
filters. Pre-flash TTL must be used when a diffuser is attached to the built-in flash, the wide-angle
adapter with the Program flash 3600HS(D), bounce flash with the Program Flash 2500(D), or an
external flash unit.
Manual flash control - fires the flash at full power, 1/2, 1/4, 1/8, or 1/16 power. The power ratio is
selected in section 2 of the recording menu (p. 64). See the following page for more on manual flash
and power ratio. Because no pre-flash is used, it can be used to fire slave flash units. Manual flash
cannot be used with wireless.
