Nikon Autofocus Speedlight SB-24 - Manual (Page 70)

TTL AUTO HD FLASH WITH NIKON F-401s/N4004s
The SB-24’s flash light output control is performed in the same
manner as the camera's built-in TTL flash. The SB-24’s light
output amount, however, is more powerful than the camera’s
built-in TTL flash.
Although the SB-24's shooting distance range is greater than
that of the built-in flash, TTL auto flash shooting operation with
the SB-24 is same as with the camera's built-in flash.
SHOOTING BRIGHT AND DARK SUBJECTS
Depending on the camera’s exposure mode, you can perform
Programmed TTL auto flash or TTL auto flash operation.
Balanced fill-flash is not possible, however, at brightness levels
darker than EV10. The camera’s computer automatically detects
brightness and chooses the appropriate flash mode.
Note that the camera’s viewfinder ready-light LED biinks to
indicate you should use a flash only when the optional flash unit
** attached on the camera is turned off. * •
• With the F-401S/N4004S camera, for correct exposure
in TTL auto flash mode, use film with a speed of ISO 25
to ISO 400.
• With the F-401 S/N4004S, l£3 mark will not appear.
