TYPE OF TTL AUTO FU\SH
TTL auto is recommended for most common flash shooting
situations. With the Nikon Speedlight set for TTL auto flash (see
chart on page 108 for compatibility), Automatic Balanced Fill-
Flash or Standard TTL Flash is performed.
Using Standard TTL Flash control, a Speedlight tends to give
more illumination than needed on the main subject, resulting in
an unnaturally bright subject with a dark background. With
Automatic Balanced Fill-Flash, flash output is automatically
compensated to balance with ambient light, resulting in a better
exposure for both subject and background.
The type of TTL auto flash performed by the N90 depends on
the speedlight and lens combination in use, as well as on the
metering system and exposure mode you are selected.
