TTL flash With the TTL flash system, the camera measures the flash of a speedlight reflected from the subject to obtain the proper level of flash illumination. TTL flash-exposure compensation Example: Before compensation Example: After compensation In flash photography when the main subject is far away or near the edge of the viewfinder frame, overexposure may occur, as the reflected light may be insufficient. This may cause excessive flash illumination. Flash photography with a bright background may also give unnatural results. In such a situation, shooting with the TTL flash-compensation button held pressed can automatically reduce the level of flash illumination for more natural and better ex- posure results. When the TTL flash-compensation button Nikon is used, the illumination of the speedlight is automatically compensated (reduced) by 1 EV to the - side. • There is no indication regarding the flash-exposure compensation when you press the TTL flash-compensation button. • If exposure compensation is made by the camera, the level of flash illumination is controlled by adding this compensation level. • The flash-exposure compensation function of the speedlight is disabled in TTL mode. 33
