Close-Up Flash Photography In Ttl Mode - Nikon Autofocus Speedlight SB-22 Instruction Manual

CLOSE-UP FLASH PHOTOGRAPHY IN TTL MODE

When used with the Nikon F-501/N2020, F-401/N4004,
F-301/N2000, FA, FE2 or FG cameras, the optional TTL
Remote Cord SC-17 lets you perform flash shooting
with a subject closer than 0.6m,
1. Use the SC-17 to connect the SB-22 and camera.
(See SC-17 instruction manual.)
2. Position the SB-22 and tilt the flash head down so
light from the flash head covers the subject.
3. Regardless of the lens in use, use the wide-flash
adapter.
4. To determine aperture, use the following equation:
f/stops
flash-to-subject distance
where A corresponds to the film in use according to
the table below:
ISO film speed 25
A
2 2,2
*For F-501/N2020 and F-301/N2000 only.
A
32 40 64
50 80
2,5 2.8 3.2
3.5
If you are using ISO 100 film for example, and the
flash-to-subject distance is 0.5m, divide 4 by 0.5 to
get f/8. That means you can use an aperture of f/8 or
smaller. Use as small an aperture as possible.
5. Set the flash mode selector to TTL, turn on the
SB-22 and take the shot.
With very light- or dark-toned subjects, make expo­
sure compensation with the camera's exposure com­
pensation dial.
