Checking the correct exposure before shooting
You can determine whether the subject will receive the correct exposure by test
firing the SB-80DX before actually taking the picture.
l
TTL auto flash mode
m Press the SB-80DX’s MODE button until “A” (Non-TTL auto flash) appears on
the LCD panel. Set the same aperture on the SB-80DX as set in the TTL auto
flash mode. Press the h button to fire the flash. If the ready-light blinks
after firing, this indicates the light may have been insufficient for correct
exposure. In this case, set a wider aperture on the camera or lens, or move
closer to the subject.
l
D-TTL auto flash mode
m Press the SB-80DX’s MODE button until “B” (Auto Aperture flash) appears
on the LCD panel. Set the same aperture on the SB-80DX as set in the D-TTL
auto flash mode. Press the h button to fire the flash. If the ready-light
blinks after firing, this indicates the light may have been insufficient for correct
exposure. In this case, set a wider aperture on the camera or lens, or move
closer to the subject.
l
Non-TTL auto flash mode
m Make the necessary settings on the SB-80DX and camera, and press the
h button. If the ready-light blinks after firing, this indicates the light may
have been insufficient for correct exposure. In this case, set a wider aperture
on the camera or lens, or move closer to the subject.
l
Auto Aperture flash mode
m Make the necessary settings on the SB-80DX and camera, and press the
shutter release button slightly, then press the h button. If the ready-light
blinks after firing, this indicates the light may have been insufficient for correct
exposure. In this case, set a wider aperture on the camera or lens, or move
closer to the subject.
l
Manual flash mode
m In manual flash mode, checking the correct exposure cannot be performed
by test firing. Calculate the correct flash output level, aperture, and flash
shooting distance by referring to “Determining the aperture and flash output
level in the Manual mode” (p. 44).
