Nikon SB-28 - Manual (Page 62)

When shooting subjects closer than 0.6m (2 ft), use your SB-28 off
camera and utilize its built-in wide flash adapter.
1 Connect the SB-28 to your camera using the optional TTL
Remote Cord SC-17.
• For F5 cameras with a High-Magnification Finder DW-30 or DW-31, use the
optional TTL Remote Cord SC-24.
• For F4 cameras with a High-Magnification Finder DW-20 or DW-21, use the
optional TTL Remote Cord SC-24.

or Manual (M).
—For cameras with VARI-PROGRAM or SIMPLE mode, close-up flash
photography is easy by setting the camera to the Close-Up mode.

f/stop = ————————————
flash-to-subject distance
*Numbers in parentheses ( ) represent coefficients in feet.
For example, with a subject 0.5m (1.6ft) away using ISO 100 film and the wide flash
adapter in place, the suggested aperture is:

f/stop = —— (in meters) = 8,
0.5
Therefore, you should use f/8 or a smaller aperture, such as f/11.
