Ambient light is any light in the viewing room created by a source other than the projector or screen (daylight, overhead lighting, hallway lighting, etc.). Ambient light differs in each space and, depending on the space, can be controlled. Ambient light reflects off the screen and washes out the image. The more ambient light there is in a space, the brighter the projector has to be and/or the darker the projection surface needs to be in order to increase the contrast ratio. More...
Scenic designers use Netting and Gauze fabrics in combination with other scenery and lighting to create visual illusions and spatial depth. The transparency of netting and the translucency of gauze make these fabrics particularly well suited for these effects. The following describes the characteristics of various nettings and gauzes and how you might use them to best effect. More...
Here's a response to a customer inquiry that might also be of interest to many others...
Issue: "I am trying to front project on the scrim with a projector that conceals the set behind it with good light control. Please suggest a scrim for me and anything I should be aware of."
Response: Projection onto scrim can be a bit tricky but if you know some of the ins and outs you should be able to avoid the challenges associated with this effect.
All of our (scrim products) can be used for projection but typically theatrical projection is done on the old standby of white sharkstooth scrim. I have also seen projection done on elements of painted black scrim and scenic painted scrims. We have seen many desirable front projection effects and images produced on black scrim that has been sprayed (on the front) with rear-projection Screen Goo, as this makes a great reflective surface for the image on a black substrate. I personally do a lot of outdoor projection onto vinyl mesh like textilene or speaker mesh with great results. The scrim material chosen will depend on your application and the desired seamless area.
The effect of a scrim heavily depends on the control of stray light. It uses contrast to fool the eye into thinking that the material is opaque. Traditional theatrical scenic scrims are typically lit from a very steep angle so that the light that passes through the scrim falls just upstage or in the wings. As long as the space and objects behind it stay dark, you will not see anything through the scrim. If there is front light hitting the scrim straight on, or at a shallow angle, it will illuminate the area and objects behind the scrim. This is true for direct and reflected light from the stage.
When you apply this to projection, things will get a bit more complicated. The ideal setup will depend very heavily on a number of variables; the effect to be achieved, desired quality and purpose of the projection image itself, and the technical capabilities of the venue. All of this is assuming front projection on scrim since rear projection is not advisable and is typically done for effect only.
If your primary concern is projection image quality, you will likely want to put the projector in the house straight on to the scrim. This will produce the best quality of image but is the worst case scenario in terms of making a scrim appear opaque. This is typically how scrim projection is accomplished but it will likely require a blackout immediately upstage of the scrim. This blackout will catch all of the projector overshoot and certainly mask the scenery or stage behind it. Just before the reveal is made through the scrim, the blackout will be flown out or traveled open. If you are looking for a double image, the blackout may not be necessary at all as the background would be dimly lit the entire time.
If you are looking for less quality of image and more effect, the projector(s) can be placed at a sharp angle to the scrim and blended into one image similar to the way your stage lighting would be. This requires equipment capable of this type of image warping and will certainly reduce the overall quality of the projected content. This can be a technically complex setup and will require the appropriate projectors and image processing.
Rose Brand is pleased to have worked with Academy Awards® Production Designer, Derek McLane, and Art Directors, Joe Celli and Gloria Lamb, to develop the main curtains and projection screens for Oscar® night.
Two Complementary, Contrasting Curtains
After weeks of collaboration and testing, the team arrived at just the right fabric, production technique and colors to achieve master designer Derek McLane’s creative vision. The 2014 curtain design involved two drapes that both featured Rose Brand white Poly Satin fabric with similar digitally printed design patterns. However, the curtains were printed in contrasting colors and sewn with different levels of fullness.
The main curtain, sewn with 150% fullness, featured a printed silvery background and dark fleur-de-lis pattern. The complementary curtain, which hung above the main drape, adorned the stage arch. The arch curtain, sewn with 75% fullness and printed in contrasting colors, provided a dramatic counterpoint.
Production of the arch curtain was particularly tricky since its fullness differed from the main curtain, but its printed pattern needed to match the main. Additionally, the top border of the arch curtain had to conform to the curved shape of a pipe located next to it. Since there was no time to re-work any aspect of the project, curtain production needed to be flawless. And it was. Once lit, the curtains produced a stunning effect!
Rose Brand also produced the projection screens used for parts of the show, including the memorial sequence. Our Black-130 Premium Projection Screen, placed in front of a video wall, produced high contrast, rear projected images, and eliminated the pixilation that would have otherwise been observed (see images below).

See projection artist Ross Ashton's FANTASTIC sound & light show, celebrating Dartmouth College's Hopkins Center for the Arts 50th anniversary. The front of the Hopkins Center features several enormous arched windows, each of which was covered with a Rose Brand Tendo fabric projection screen and attached to the steel window frame via Rose Brand ClikMagnets.
Tendo fabric provides for an exceptional projection screen. It's highly reflective, lights evenly and cost effective. It's also stretchable and lightweight, making it much easier to install than traditional vinyl screens. Wrinkles simply stretch away. The lightweight aspect of the fabric enabled installation onto the steel window frames with our convenient ClikMagnet product. If you'd like to read more about how the effects for this event were achieved, the projectors used, etc. please see the article that appears on the Live Design blog.
On August 10, 2012 special guests of the United Nations filled the General Assembly Hall in New York to celebrate World Humanitarian Day. This day honors the humanitarian efforts that take place across the globe and seeks to motivate active participation in social causes. During the event, Beyoncé inspired the crowd with a performance in front of projected images of humanitarians working and helping those in need. At the request of the SuperUber design company, Rose Brand developed the projection screen for the event, the largest compound curved indoor screen ever created.
The 1,000 pound, 46’ high x 224’ wide screen was pieced together in Rose Brand’s NJ warehouse by a team of sewers who worked around the clock for two days due to the urgency of the task. Once hung, the screen molded to the unique architecture of the General Assembly Hall. Building a screen of this magnitude, in a room that was not designed for theatrical lighting projections, made the choice of screen fabric particularly important. SuperUber chose the white/white blackout lining after testing a number of fabrics, due to its opaque characteristics. It insured that light would not transmit behind the screen, and it created a flawless projection surface.
After fabricating and transporting the massive screen to the UN, Rose Brand provided a complete rigging package and installation service with the help of the Local 1 Stagehands. Due to the lack of rigging points, permanent steel plates had to be welded into the existing structure in order to support the weight of the 6,000 pound supergrid system. Once installed, the screen was comprised of ten synchronized and mapped projections that created one giant image. The screen surrounded the audience with a 240 degree immersive projection, creating an unforgettable and inspirational experience for those in attendance.

Every four years, athletes from countries of the Americas compete in the Pan American Games. Each year, the host country tries to outdo their predecessor by creating a spectacular artistic presentation in the opening ceremony. The 2011 games taking place in Guadalajara, Mexico were no exception with an Opening Ceremony reportedly costing $20 million.
Rose Brand was instrumental in the construction of the focal point of the ceremony, a three dimensional moving projection screen. The screen's steel frame boasted a circumference of 350 feet and hung in the center of the stadium. The projection screen, made out of Rose Brand’s Rip Stop Nylon, was 104 feet tall and offered a 360° cylindrical projection surface.
PRG Technologies, the engineer on the project, engaged Rose Brand to build the projection screen in just a single week. In order to fabricate the three dimensional screen, Rose Brand sewed together 3,200 yards of Rip Stop Nylon. The screens were made up of two pairs of panels measuring 104’9” x 98’ and 104’9” x 51’. The enormous projection screens, equivalent in height to a ten story building, were adorned with 3,600 D-rings that were hand sewn onto the panels to give the projection screen mobility.

The halo at the top consisted of 72 overlapping fabric panels each measuring 22 feet in length. Since it was critical that each panel's measurements were identical, we used Rose Brand's Precision Laser Cutting process to ensure accuracy. View the sewing plans for the halo here: halo plans.pdf
Rose Brand congratulates our fourth blog contest winner, the team at InOvation Group. Their blog entry described how they built a projection header and “Chinese Lantern” balls on a tight budget for the First Bank Center Arena in Broomfield, Colorado. Here is how THEY did it...
Project Description –
InOvation Group was approached in January of 2010 by AEG Live and Kroenke Sports Enterprise to design and supply a VERY large custom projection header piece for use in the new First Bank Center Arena in Broomfield, Colorado. The project budget was fairly tight, and the delivery date was also short. The project also asked for the design and supply of three sets of 3 large “Chinese lantern” balls, which could change color and have custom designs applied to the surface to provide a silhouette look.
Design Challenge –
The header size (132’ in width x 43’ at tallest point) had to be installed and/or More...
