TTL AUTO FLASH—Automatic Balanced Fill-Flash and Standard TTL Flash
Types of TTL Auto Flash
TTL auto is recommended for most flash shooting conditions.
With a compatible Nikon TTL Speedlight set for TTL auto flash
operation (see chart on page 124 for compatibility), you can
choose from either Automatic Balanced Fill-Flash or standard
TTL flash.
Standard TTL flash, while automatic in operation, does not
automatically compensate for complex lighting conditions. With
Automatic Balanced Fill-Flash, working together with the 3D
Color Matrix or Center-Weighted Metering, flash output is auto-
matically compensated to balance the ambient light exposure
setting. The result is improved overall exposures and a better
balance between ambient light and the fill-flash.
The type of TTL auto flash performed by the F5 depends on the
Speedlight and lens combination in use, as well as the metering
system and exposure mode selected.
