| 1 - Scale
A typical piece of Eyeliner™ Foil is a screen of 4.1m high
in a continuous roll up to several hundred meters in length. A thinner,
8m high foil can also be used for larger installations. In instances
where even taller images are required sections of the 4m foil can
be installed in a “portrait format” where each section
is a maximum of 14m high by 4m wide, giving images approximately
11m high. Individual sections of foil are then overlapped and cut
to fit leaving 1mm seams, which are barely visible from viewing
distances over 7m.
2 - Clarity of image
Eyeliner™ Foil is less than 100 microns thick yet retains
its durable characteristics once installed. Because the foil is
so thin there is no drop shadow created when objects are projected
onto it, as there would be if a system were using glass or Perspex.
Foil allows greater amounts of projected light through for brighter
images. In simple terms this means that the Eyeliner™ medium
creates crisper, sharper and consequently more realistic representations
of the object or person being projected than any other medium.
3 - Foil can be cut
Unlike glass, Eyeliner™ Foil can be cut even when it has been
fully installed. This means that doorways and holes for props to
protrude through the foil can be easily rigged up. This opens up
lots of creative avenues for stage designers and choreographers
to explore when using Eyeliner™ in conjunction with their
other show plans.
4 - Transportation
With practical issues to think of such gaining access to some venues
through small doorways and rigging/lifting issues once on site,
glass and Perspex can prove to be unwieldy. There are no such limitations
with Eyeliner™ Foil which is transported in 5m x 30cm lightweight
pipes that can be easily carried by a couple of crew.

5 - Safety
Imagine the horrendous practical issues that would have to be considered
if you were transporting large sheets of glass from venue to venue.
Eyeliner™ Foil cannot shatter and poses no danger to crew
installing it or working along side it. Furthermore Eyeliner™
Foil can be installed into moving scenery without fear of it breaking
as it is moved. This means that it is a very straight forward process
to fly the system in and out of stages as required. Eyeliner™
Foil is certified fireproof to grade B1/VTM2 rating.
6 - Rigging time
Foil is typically rigged in a couple of hours. The rigging process
is straight-forward and Eyeliner™ installers can work alongside
other technical crew. Once installed the process of tensioning the
foil literally takes a few minutes of adjustment.
Practical Considerations When Using Eyeliner™
System
Environmental
1 - Wind
Musion® Systems has undertaken numerous outdoor jobs already
but there is always the chance that wind will blow onto the foil
and affect the projected image. (If the wind is anything more than
light, the foil may bow like a sail causing the projected image
may appear to ‘bounce’ up and down on stage). The way
to alleviate this problem is to build a wind-break around the installation.
This method had proved highly successful at previous shows where
it has been implemented.
2 - Strong daylight
This issue is pertinent in any situation where projectors are being
used as a source of video. Despite manufacturers having made great
strides in the last couple of years with the brightness of their
projectors (currently Barco offer a 30 000 lumen projector) however
there will never be anything available that will be able to compete
with natural daylight. In circumstances of strong natural daylight
the options are either to create a controlled light environment
or use the Eyeliner™ system with widescreen High Definition
3mm/6mm LED walls.
3 - Space
The Eyeliner™ Foil requires a certain amount of space both
in front and behind the foil. An area in front of the foil may be
required for the projection pit dependent on the set up. Plus an
area must be left behind the foil in order to add depth to the illusion,
a minimum of 1m should be allowed. In practice this means that the
footprint of a Musion® Eyeliner™ System installation will
be at least 3.5m deep in order to display virtual humans at full
size (up to 2m).
