Manual mode
In Manual flash photography, you select the aperture and flash output level.
This allows you to control the exposure and flash shooting distance when the
correct exposure is difficult to obtain in the TTL auto flash mode. The flash
output level can be set from M1/1 (full output) to M1/64 to suit your creative
preferences.
You can calculate the correct aperture by using the guide number table and the
shooting distance. Then, set the same aperture manually on the lens. In this case,
set the camera’s exposure mode to Aperture-Priority Auto (A) or Manual (M).
No limitation on usable cameras.
Refer to your camera’s user’s manual for details on camera and lens aperture settings.
The shutter might not be released if the camera’s exposure mode is at a setting other
than Aperture-Priority (A) or Manual (M) and the SB-600 is in Manual mode, depending
on the camera in use. For details, refer to your camera’s user’s manual.
•In the Manual mode, there is no warning ready-light to indicate that the light may have
been insufficient to obtain a correct exposure.

Determining the aperture, flash output level and
shooting distance in the Manual mode
In the Manual mode, use the guide number table and the following equation to
calculate the aperture, flash output level and shooting distance to obtain the
correct exposure.
The guide number (GN at ISO 100; m/ft) indicates the amount of light generated by the
flash. The larger the number, the greater the flash output.
