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

●●● 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.
