CLOSE-UP FLASH PHOTOGRAPHY IN TTL AUTO FLASH MODE-
When used with the Nikon F4, F-801/N8008, F-501/N2020,
F-401S/N4004S, F-301/N2000, FA, FE2 or FG, optionai TTL
Remote Cord SC-17 or SC-24, iets you perform flash shooting
with a subject closer than 0.6m (approx. 2ft.).
1. Connect the SB-24 to the camera using Remote Cord SC-17.
(See SC-17 instruction manuai.)
2. Position the SB-24 so light from the fiash head covers the
subject.
3. Regardless of the lens in use, set the angle of coverage at
the 24mm position.
4. To determine aperture, use the following equation: i
A
f/stop - fiagh-to-subject-distance ^ _
Where A corresponds to the film in use according to the table
below:
ISO film speed 25 32 40 50 64 80 100 125 160
A 2 2.2 2.5 2.8 3.2 3.5 4 4.4 5
ISO film speed 200 250 320 400 500* 640* 800* 1000*
A 5.6 6.3 7.1 8 8.9 10.1 11 13
For example:
When using ISO 100 film and the flash-to-subject distance Is
0.5m (1.6ft), divide 4 by 0.5 to get f/8. That means you can use
an aperture of f/8 or smaller. Use the smallest aperture possible.
5. Set the flash mode selector to TTL, then turn on the SB-24
and take the shot. '
• Exposure compensation is possibie with the camera's
