Introduction
Thank you for choosing the Impact Luxbanx Duo softbox. All Luxbanx softboxes
are designed to control and soften light for your specific photographic needs.
Duo softboxes are compatible with continuous light sources (including quartz,
tungsten, HMI and other “hot” lights, as well as LED or fluorescent lights) and
flash (strobe) lighting sources. Be sure to read and follow the included power
and wattage guidelines for lights that can be used with the softbox you have
purchased.
Luxbanx Duo softboxes come in four shapes: square, rectangular, strip (a long,
narrow rectangle), and octagonal. In addition, softboxes come in extra-small,
small, medium, large and extra-large sizes. A speed ring (not included) is
required to mount the softbox to a light. Each softbox has a front diffuser, which
can be attached using touch fasteners. The diffuser can be removed to produce
more intense light with increased contrast. Duo softboxes have a bright-
textured silver interior finish, which produces bright light with less light loss
than a white interior. The removable internal baffle will soften and diffuse light
when installed in the softbox.
The size and shape of the softbox is related to the lighting effect produced —
the larger the softbox, the softer the light. The distance from the softbox to the
object being photographed also affects the quality of light produced — when
the softbox is close to the object, the light will be more intense, with more
contrast. When the distance is greater, the light will be more diffused, with less
contrast. The removable interior baffle will also soften and diffuse light — you
can add or subtract a degree of contrast through inserting or removing the
baffle.
Generally, the larger the object you’re photographing, the larger the softbox you
should use.
A large rectangular or octagonal softbox will give more even light
for a full-length portrait than a small softbox. The shape of the softbox affects
the light produced as well: for a slender object,
when photographing a slender
object, use a strip softbox that has a similar shape to produce more even
light than an octagonal softbox.
