Manual flash photography (MANUAL)
Manual flash firing mode keeps the flash power level consistent regardless of the brightness of the subject or the settings of the
camera.
TTL level memory function
During TTL flash photography, a measured flash power level is automatically set as the flash power level in manual flash firing
mode. This enables you to adjust the flash power level in manual flash firing mode on the basis of the flash power level measured
during TTL flash photography, and to omit a series of operations necessary for determining the flash power level.
To change the TTL level memory function setting, select [External Flash Set.] - [Ext. Flash Cust. Set.] - [TTL Level Memory] from
the menu of the camera attached with this flash unit. By default, [On] is specified for the TTL level memory function.
Notes on using the TTL level memory function
During multiple wireless flash photography (group flash photography), the guide number varies depending on the flash
settings of individual flash units or the availability of the built-in wide panel. To retain an appropriate flash power level, specify
a different wireless group for each flash unit.
If a flash unit that does not support the TTL level memory function is used for multiple wireless flash photography (group flash
photography), an appropriate flash power level may not be retained.
In manual flash firing mode, the flash power level measured during TTL flash photography is retained. If you change the
settings that affect the flash power level, such as the flash power level setting, after photographing, the changed settings will
not be retained. When you have made such changes, perform TTL flash photography once again.
If the flash power level measured during TTL flash photography is lower than the levels available in manual flash firing mode,
the photographed images may appear over-exposed.
Work with the menu of the camera attached with this flash unit to specify [Manual Flash Firing] for the flash control
mode.
For details on the external flash settings of the camera, refer to the operating instructions supplied with your camera.
1
Press the LEVEL -/+ button on the flash unit to select the flash power level of your choice.
You can specify the flash power level in the range from 1/1 (brightest) to 1/128 (darkest).
You can view the current setting by selecting [External Flash Set.] - [Ext. Flash Firing Set.] - [Flash Power Level] from the
menu of the camera attached with this flash unit.
Decreasing the flash power by one level (e.g. 1/1 → 1/2) is equivalent to increasing the aperture by one level (e.g. F4 →
5.6).
2
Press the shutter button on the camera to take a photo.
Wait until the TEST button on the flash unit lights in orange (ready to fire), and then press the shutter button.
