Nikon os Speedlight SB-102 - Manual (Page 27)

Non-TTL Automatic Flash Exposure Compensation
When shooting in the non-TTL automatic flash exposure
mode, exposure compensation can be made by stop­
ping down or opening up the lens. To compensate for
a dark subject, use a 1/2- to 2-step smaller aperture
(a numerically larger f-number). To compensate for a
light subject, use a 1/2- to 2-step larger aperture (a
numerically smaller f-number).
Ready-Light
After its power switch is turned on, the ready-light on
the SB-102 will light to indicate that the SB-102 has re­
cycled and is ready to fire. If you are using either a
Nikonos-Vor Nikonos IV-A camera, its viewtinder ready-
light will also light at the same time to let you know the
flash unit is ready for the next shot.
In addition, the viewfinder ready-lights of the Nikonos-V
and Nikonos IV-A blink to warn of improper settings. If
this happens, check that the camera and flash unit are
securely connected, and the shutter speed/shooting
mode and ASA/ISO film speed on the camera are
correctly set.
• The ready-light will light up when the SB-102 has recycled to 80% of
its full capacity. Therefore, if you want to shoot a subject at either the
minimum or maxim um camera-to-subject coupling distance in the
non-TTL automatic mode or one of the manual modes, it is best to wait
until a few seconds after the ready-light has lighted.
•/As the voltage of the batteries decreases with use, the GN of the flash
unit decreases slightly.
• The voltage of NiCd batteries decreases rapidly when their power is
almost exhausted, increasing the recycling tim e. W hen this occurs,
stop using them immediately and recharge them or they may be
damaged.
• W hen using alkaline-manganese batteries, if recycling takes 30
seconds or longer, replace the batteries with a fresh set.
• The ready-light goes out when the flash unit is turned off.
• W hen the exposure meters of the Nikonos-V and Nikonos IV-A are not
activated, the cameras' viewfinder ready-lights will not light even if the
speedlight is turned on (except when the shutter speed/mode selector
dial or shutter speed dial is set at M90 or M). Always confirm that the
viewfinder ready-light is lighted before shooting.
• W hen the shutter speed/mode selector dial or shutter speed dial of the
Nikonos-Vor Nikonos IV-A is set at M90 or M, the viewfinder ready-light
lights when the flash unit's ready-light lights.
Warning Function: Beyond Auto Shooting
Range
In the TTL and non-TTL automatic modes, the ready-
lights on the flash unit and in the camera’s viewfinder
blink for approximately 2 seconds if the flash unit has
fired at its maximum output to indicate that the light
output may not have been sufficient for correct expo­
sure. If this happens, recheck the flash-to-subject dis­
tance. If it is beyond the coupling distance range, use
a larger aperture (a numerically smaller f-number), if
possible, or move closer to the subject.
Because the voltage of batteries (especially alkaline-
manganese batteries) decrease rapidly with use, the
GN of the flash unit will decrease slightly. The flash
output of the SB-102 also varies according to the
amount of ambient light and the subject's reflectivity.
