Non-TTL Auto flash
When using the Auto flash mode, the mon-
itor pre-flash solely determines the flash
output. To adjust the exposure you simply
change the aperture value in your camera
settings.
To use this mode:
1. Set your camera to Aperture
Priority (A) or Manual (M).
2. Press the Mode button on the
SB-800 Speedlight until A
appears on the LCD.
3. Press the + or – buttons to
adjust the aperture setting on
the flash.
4. Set the aperture on your camera
to match the setting on the
flash.
5. Make sure your camera is set to
the proper flash sync shutter
speed. Your camera does not
allow you to set a shutter speed
higher than its rated sync speed.
6. Check the ready light and then
shoot.
Guide number distance
priority
The SB-800 controls the flash output
according to aperture and subject distance.
You manually enter the distance and f-stop
value into the Speedlight, and then select
the f-stop with the camera. The flash output
remains the same if you change the aper-
ture. You can use this mode when you know
the distance from the camera to the subject.
To use this mode:
1. Set your camera to Aperture
Priority (A) or Manual (M).
2. Press the Mode button on the
SB-800 Speedlight until GN
appears on the LCD.
3. Press the multi-selector button
to highlight the distance display
then press the + or – buttons to
change the distance range.
4. Set the aperture on the camera.
5. Check the ready light and then
take the picture.
Repeating flash
In this mode, the flash fires repeatedly like a
strobe light during a single exposure. You
must manually determine the proper flash
output using the formula to get the correct
aperture (GN ÷ D = F-stop), and then you
decide the frequency and the number of
times you want the flash to fire. The slower
the shutter speed, the more flashes you are
able to capture. For this reason I recom-
mend only using this mode in a low-light
situation because the ambient light tends to
overexpose the image. Use this mode to
create a multiple exposure type image.
To use this mode:
1. Set the camera to M.
2. Press the Mode button until RPT
appears on the LCD.
3. Use the SB-800’s center Multi-
selector button to highlight the
flash output level and then use
the + or – buttons to change the
levels.
