TTL auto flash mode

TTL auto flash mode: 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. When performing Balanced Fill-Flash, however, 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.
