13 Correct exposure indication
The correct exposure indication „OK“

only lights up
if the shot was correctly exposed in TTL flash mode
(3D-TTL, D–TTL, i-TTL, etc.) or automatic flash mode.
If no „OK“ exposure indication

appears after the shot, then the shot was
underexposed. You will need to repeat the shot with the next smaller f-number
(for example, f/8 instead of f/11), or the distance to the subject or reflecting
surface (for example with bounce flash) will have to be reduced. Note the maxi-
mum flash range indicated on the display of the flash unit (see 16). For informa-
tion on the correct exposure indicator in the camera viewfinder, see also 15.
14 Underexposure warning in TTL flash mode
In certain modes („P“ and „A“, for example), some Group C, D and E Nikon
cameras (see Table 1) respond to an underexposed flash shot with a warning on
the display of the flash unit, indicating the amount of underexposure in
f-stops (see the camera’s operating instructions).
If the correct exposure indication „OK“

does not light up on the flash unit
after a flash shot is taken, or if the flash symbol blinks in the camera viewfinder,
then the display of the flash unit will briefly indicate the underexposure in f-stops
ranging from -0.3 EV to -3.0 EV in one-third increments.
In borderline instances the flash unit will not display an „OK“, or the flash sym-
bol will blink in the camera viewfinder, even though the exposure is correct. In
this instance, no indication will appear on the LC display of the flash unit.
To enable underexposure warnings, the TTL mode (or 3D-TTL, D-TTL,
i-TTL, etc.) must be set on the flash unit.
