Close-Up Flash Photography in TTL Auto Flash Mode — To Flash On A Very Close Subject
Optional TTL Remote Cord SC-17 or SC-24 lets you perform
TTL Auto Flash shooting on a subject closer than 0.6m (2 ft.).
Hints and Notes
• Connect the SB-25 to the camera, using the SC-17 or
SC-24*.
* Used for F4-Series with the DW-20 or DW-21 attached.
• Position the SB-25 so light from the head covers the sub-
ject.
• Mount the built-in flash adapter.
The zoom-head position is automatically adjusted.
Confirm the LCD panel shows with indica-
tion.
• Use aperture-priority auto or manual exposure mode.
• Choose position (flash mode selector) for TTL Auto
Flash operation.
For further instruction, see the TTL Auto Flash Mode
section relating to your camera type.
• Determine the aperture or f/stop value using the following
equation and chart, then set on the lens. The SB-25’s LCD
panel cannot be used to compute shooting distance.
[f/stop] ≥
[coefficient]
[flash-to-subject distance]
For example, to shoot a subject located 0.5 m away with
an ISO 100 film and a wide-flash adapter:
[f/stop] ≥
4
= 8
0.5
You can then use an aperture of f/8 or smaller (a larger f-
number). As far as conditions allow, you should choose
the smallest aperture (as large an f-number) possible.
• With a very light- or dark-toned subject, take additional
shots with other exposure compensation conditions to
ensure a correct exposure.
See “Flash Exposure Compensation” on pages 106 and
107, and “Exposure Compensation with Camera’s Dial” on
pages 108 and 109.
