TTL auto flash: D
In this mode, the flash illumination that is reflected back from the subject is
detected by the camera’s TTL auto flash sensor and the camera automatically
controls the flash output level to give the correct exposure.
Automatic Balanced Fill-Flash: Do
Press the a button to display Do on the LCD panel, and Automatic
Balanced Fill-Flash is performed. The flash output level is automatically
adjusted for a well-balanced exposure of the main subject and background.
(While performing Balanced Fill-Flash, no o appears with cameras in Groups
III and IV.)
• Do indicates “i-TTL Automatic Balanced Fill-Flash” in the i-TTL mode.
Standard TTL flash: D
Press the a button to display D on the LCD panel, and Standard TTL
flash is performed. The main subject is correctly exposed regardless of the
background brightness. This is useful when you want to highlight the main
subject.
• D indicates “Standard i-TTL flash” in the i-TTL mode, “Standard TTL flash for Digital
SLRs” in the D-TTL mode, and “Standard TTL flash” in the TTL (film-based) mode.
t Notes on TTL mode indicators
Comparison tables are provided on pages 108-110 to show the SB-800’s TTL
mode indicators and the corresponding ones used in the current Speedlight
instruction manuals.
• For details on shooting procedures in the TTL auto flash mode, refer to “Basic operation”
(p. 17).
t Flash shooting in the 1/300 TTL High-Speed Flash sync mode
(F5 only)
The farthest flash shooting distance cannot be read on the SB-800’s LCD
panel. In this case, use the guide number table and equation (p. 106) for
calculating this distance, according to each zoom-head position.
