USABLE FLASH MODES WITH YOUR CAMERA

modes—TTL Auto UD , Non-TTL Auto El, Manual BJ or
Repeating-Flash SS . When the power switch Is on, the flash
mode Indicator confirms your selection in the LCD panel.

In this mode, the camera’s TTL flash sensor measures all the
light which passes through the camera’s lens and reflects off
the film surface. This includes both ambient light and light from
the SB-24 flash. The flash shuts off at the moment the sensor
detects the correct exposure. Because the sensor detects light
passing through the lens, it automatically adjusts for most flash
shooting situations, including bounce flash, diffusion filters and
colored or neutral-density filters used on the lens or on the flash
head.
The SB-24's automatic flash operation depends on the Nikon
SLR model used. The chart on the following page indicates the
automatic modes available for each SLR model shown.
Subsequent sections of this instruction manual explain each of
the different automatic modes.
Available flash features also vary depending upon the type of
Nikon lens used and camera on which it is used. The newest AF
Nikkor lenses include built-in computers, and used with the
newest Nikon SLR models (F4, F-801/N8008, F-401s/N4004s)—
which incorporate a computer and multi-segment light meter—
provide the most advanced flash operation, known as Matrix
Balanced Fill-Flash.
