soft reflector on one side, black on the other, or black on both sides. Can be
used on windows as ND cutting 2 stops.
What does Rosco Sun 85 do? Answer - A color correction gel that lowers the
color temperature of daylight to balance with 3200k sources.
What does CTB do? Answer - Color Temperature Blue is a color correcting gel
that converts light from 3200k to 5600k. Typically found in full, 1/2, 1/4, and
1/8.
What does the CTO do? Answer - Color Temperature Orange is a color
correcting gel that converts light from 5600k to 3200k. Typically found in full,
1/2, 1/4, and 1/8.
What is the difference between a single and a double net? What is a triple?
Answer - Nets are non-electrical dimmers used in front of lights to cut light
transmission without changing the quality or color of the light. A single net has
a green or white trim and reduces light by 1⁄2 stops while a double net has a red
trim and reduces light by one full stop. A triple cuts light by 11⁄2 stops, but may
create a moiré pattern on the subject.
How much light does a Lavender reduce light by? Answer - A lavender reduces
light by 1/3 stop and has a purple trim.
,What is a Butterfly Kit and what does it include? Answer - A butterfly kit
includes four lightweight frame sides, four corner connectors, and two ears
used to mount the completed frame on stands. A complete basic rag set
includes a solid, a single, a double, a silk, and a grifflon. Butterfly frames 12'
and up are considered overheads.
What is the difference between taffeta and china silk in terms of lighting?
Answer - China silk is real silk fabric which is expensive and delicate. Taffeta silk
aka poly silk is synthetic silk which is more economical and durable. (Uva 90)
Taffeta softens and diffuses direct light while China silk softens light without a
great reduction of intensity. Taffeta is also heavier and cuts more light.
How does one store silk? Answer - Silk must always be stuffed or wrapped in a
ball. This is to prevent creases that would otherwise cast shadows on the
subject.
What is Bobbinet and what lengths does it come in? Answer - The net we use
to make our scrims. Light weight cotton gauze with hexagonal weave; 1/8" to
3/16" openings. Up to 31' in width.
What is the practical difference between bleached and unbleached muslin?
Answer - Bleached muslin is white in color and reflects a white bounce and
transmits a diffused white light. Unbleached muslin has a slightly yellow hue
which creates the same lighting effects but with a lighter color temperature.
What sizes do fingers and dots come in and what are they used for? Answer -
Standard dot sizes are 3", 6", and 10" in diameter. Standard finger sizes are
2"x12" and 4"x14". Used to alter or correct and isolated, internal segment of
light without affecting the overall pattern. Commonly used for table top setups.
What size do flags and cutters come in? Answer - Flags are usually closer to
being square in shape while cutters are longer and narrower. Many flag sizes
, are available, but the most common are:18"x24", 24"x36", 48"x48". Cutter
standard sizes: 10"x42", 2"x36", 18"x48", 24"x 60", 24"x72".
What size do empty frames come in? Answer - Standard open frames: 18"x24",
24"x36", 48"x48"
What is Grifflon made out of? Answer - Grifflon is an extremely durable
material made of three- ply, high-density rubber with a rip stop layer. It takes
direct light and bounces it back onto the subject.
What does a reflector do? Answer - A reflector or mirror board redirects light
using a mirror. A reflector board also has a soft side, which diffuses the light.
What is ND and how does it work? Answer - A Neutral Density filter subtracts
light without changing the color temperature by absorbing the light of all colors
equally. Great for reducing light on windows. ND.3 reduces light one stop, ND.6
reduces light 2 stops, ND.9 reduces light 3 stops.
What is the difference between Minus Green and Plus Green? Answer - Plus
green adds green to lights to match their color to that of fluorescent bulbs.
Minus green is a magenta gel used to take the green out of fluorescent lights.
Why is green screen better than blue screen? Answer - Green screen is
preferable mostly because green occurs less in wardrobe.
Black single Answer - Cuts light a half stop
White single Answer - Cuts light half stop with white return
Black double Answer - Cuts light full stop
