film in the camera to test the TTL function!
i-TTL and D-TTL flash mode
The i-TTL flash mode is supported by cameras of Group E, the D-TTL flash mode
by cameras of Group D (see Table 1). i-TTL and D-TTL flash modes are advan-
ced variants of the normal TTL flash modes used with analogue cameras. Before
shooting, the flash unit fires a series of barely visible measuring preflashes. The
camera evaluates the reflected preflash light so that the subsequent flash expo-
sure is optimally adapted to the prevailing photographic situation. According to
the evaluation, the following flash exposure is adjusted by the camera to the
shooting situation (for more information see camera's operating instructions).

i-TTL BL and D-TTL 3D flash mode
These digital TTL flash modes are only supported by cameras of the Groups E or
D if lenses are used that transmit distance data to the camera (for example,
„D–AF Nikkor lens"). When shooting this data is taken into consideration in
addition in adjusting the flash exposure.
