Close-up flash operation in TTL Auto Flash t Mode

When shooting subjects closer than 0.6m (2 ft), use your SB-28 off camera and utilize its built-in wide flash adapter.

1Connect 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.

2Set the exposure mode to Aperture-priority auto (A) 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.

3	Set the aperture.
	—Calculate the aperture (f/stop) by using this equation and table.
		coefficient
	f/stop = ————————————
	flash-to-subject distance
	ISO film speed and coefficient
	ISO film speed		100 or lower	125–400	500 or higher
	Coefficient*		4 (13)	8 (26)	11 (36)

*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:

4	13
f/stop = —— (in meters) = 8,	f/stop = —— (in feet) = approx. 8
0.5	1.6

Therefore, you should use f/8 or a smaller aperture, such as f/11.
