Pentax P3 - Bulb (B) Setting for Long Exposures

USING B (BULB) SETTING
The B setting Is used for making long-time exposure
to shoot fireworks, night scenes, etc.
• As shown in the photo, align "B” in the shutter
dial with the Index (red bar). Make sure the
aperture of your SMC Pentax-A lens is set to
a proper f-stop other than A. The shutter remains
open as long as you keep the shutter button
depressed.
• The long-time exposure consumes a great amount
of battery power; it will exhaust fresh batteries in
about ten hours at norma! tempratures.
• When shooting at this setting, use a sturdy tripod
and as shown, also use the optional Cable Switch
A or Cable Release 50 (Time exposure possible).
• Be sure to use the Cable Release 50 without
twisting or bending it; otherwise the B-setting
photography may not properly be done. Always
push the head of the Release hard to release
the shutter. The Cable Release 30 is not suitable
for use.
