Benefits:
More and more, the majority of work
for cinematographers/videographers involves
the use of a blue or green chroma screen.
You may not realize it, but you probably
see the results every day... the local
news weathercasts, major motion pictures,
music videos, corporate videos, broadcast
commercials and, of course, "cheesy
YouTube spoofs", are all beginning
to rely heavily on this technology.
Even simply combining a quality chroma
key setup with either stock footage
or a photo-realistic "Virtual
Set" can offer clients an avenue
that allows you to be both creative,
and competitive, and the results are
spectacular. This can increase business
in a big way, especially through referrals
in the corporate realm.
History:
Reflective fabrics have been around
since the 1930's, and using a ring of
light around the camera lens has been
around for decades, especially for still,
microscopic, dental, and technological
quality control applications. Even the
process of camera-mounted lights used
in conjunction with a reflective backdrop
has been utilized in different capacities,
for many years, even prior to the advent
of "chroma key". In the late
1990's, to my knowledge, the pursued development on a highly specialized
fabric that offered better functionality
for chroma key applications. This fabric,
created through their own patented process,
was initially called "TrueMatte",
and later deemed "Chromatte TM".
It was subsequently combined with the
LED lens ring and marketed as the "Holoset"
system by Play, later becoming "Reflecmedia",
who is still active in producing an
amazing product. Their system can be
found in network and broadcast studios
around the world. Recently, Datavideo
began to market a slightly more economical
version of this approach, also using
a ring of LED's, but with a different,
yet highly effective fabric. Both are
great systems and I highly recommend
them.
Why My Own System?:
Since one of my gigs is a video production
company with the need for a quality
chroma key setup, I bought one of the
above systems and was immediately and
forever spoiled--I can't imagine going
back to the old way of doing it. The
existing, standard packages come with
roughly an 8ftx8ft retro-reflective
backdrop, as did mine. An upcoming project
this summer, however, mandates having
much more than the 8ftx8ft backdrop
material on hand, and the price of the
highly specialized reflective material
($32 per square foot at BH) would make
it non cost-effective for the size I
need, which is well over 20ft x 20ft.
After an arduous search through industry
contacts, having samples sent from all
over the world and thoroughly testing
each, I found an alternate fabric that
worked very well for this purpose (and,
man, it ain't cheap!!!!). Since it is
only available in extremely large quantities,
a bit of contemplation ensued: By pulling
in these monster rolls of wholesome
goodness, "What does one do with
the rest of it?" Fortunately, one
of my other gigs is a music product
manufacturing company, and I am very
familiar with the ins & outs of
developing a quality product. To couple
with the extra material, I decided to
produce a handful of unique LED rigs
within this principle, allowing me to,
hopefully, recoup some of my material
costs, and maybe provide an avenue for
this type of system to those who might
not otherwise be able to afford it,
since these are priced at about 1/4
to 1/3 the price of what it presently
available.
"Okay... why the weird design?"
Some of the initial enclosure tests
were die cast aluminum. That, combined
with the aesthetics of the silvery machined
knob and the glowing, circular LED's,
made it look a bit "otherworldly"
to me. Even after switching to an ABS
enclosure to avoid grounding loops,
I felt the initial motif still applied,
especially with the amber indicator.
Something had to go on top to avoid
an odd blankness, so I had it silk-screened
with a silver powder, in a design that
is a slight variation on the infamous
1990 Alton Barnes crop circle, entirely
because I thought the shape and balance
really worked well with the knob, without
losing the "found buried in the
deserts of New Mexico" vibe. I
hope my modifying it doesn't spur an
intergalactic incident by insulting
some omnipotent leader, somewhere? It's
not like much other info needs to go
on top: "Lefter dimmer, Righter
brighter", so I had a bit of freedom
to just concentrate on the aesthetics.
