Tilting/Rotating flash head
• The SB-25’s flash head tilts and rotates as shown at right.
• The flash head locks at the front/horizontal and vertical
(90° upward) positions. To release, use the tilting or rotat-
ing lock release lever.
LCD panel
• The LCD panel cannot be used to compute flash shooting
distance when the flash head is tilted upward or rotated
away from the horizontal/front position. In these cases, the
shooting distance indicator bars
do not appear in the
LCD panel.
• The shooting distance indicator bars blink when the flash
head is tilted downward to the -7° position. This position
is used to shoot a subject within 1.5m (approx. 5 ft.).
Tilting: up to 90° — front — down to –7°
Rotation: to right 90° — front — to left 180°
For F90-Series/N90 users
In bounce photography with the flash head tilted or
rotated, the SB-25 does not fire Monitor Preflash(es),
even for 3D Multi-Sensor Balanced or Multi-Sensor
Balanced Fill-Flash operation.

Built-in diffuser card for bounce flash photography
• Use the diffuser card to create a catchlight for the sub-
ject’s eyes, an effect that is not always available in bounce
flash photography.
• The diffuser can be used to provide supplemental light to
the face or front of the subject, thereby brightening shad-
ows created by top-lighting or bounced flash from the
ceiling.
