To Set TTL Flash
1.
Activate the flash by turning its Power switch to
ON
.
2.
Select the type of TTL to be performed. Basically, you
only have one choice: whether to cancel the
“balanced fill-flash” mode (you can do so on a D300
only by selecting Spot metering on the camera); see
“Summary of i-TTL Flash Modes,” on page <604>).
3.
Set the camera to Single Servo AF (flash only operates
when the camera achieves focus; this isn’t technically
required, but I like to tell people to use it as a
reminder that focus has to be achieved for flash to
operate).
4.
Set the camera’s exposure mode, if you haven’t
already. In Aperture-priority (A), Shutter-priority (S),
and Manual (M) exposure modes, make any necessary
aperture or shutter speed selections.
Note: In Program exposure mode you can usually override the
camera’s selection of aperture and shutter speed
combinations by turning the D300’s Rear Command dial
(when the camera is active). But note that the maximum
aperture you can use is restricted in Program exposure
mode (the actual value depends upon ISO setting; see
“Allowable Apertures in Program Mode,” on page <598>.
Note: The D300 may warn you of several possible errors when
you partially press the shutter release to verify settings:
- The lens must be set on its minimum aperture, or else the
error message
FEE
appears in the viewfinder.
- Any
HI
visible in the viewfinder indicates that
overexposure (of the background exposure) is likely.
- The shutter speed will be automatically reset to 1/250 if
you selected a faster shutter speed in Shutter (S) or Manual
(M) exposure mode. (If FP is set, however, the camera will
use any shutter speed.)
- In Manual (M) exposure mode, under and overexposure is
indicated solely by the analog exposure display. If the
exposure bar goes to either side of the
$
point, the ambient-
only lighting exposure will not be correct.
