It’s a well-known fact that moving light manufacturers include a set of stock gobos in every unit they make. With that in mind, it’s good to remember that those gobos can be replaced with patterns that fit the need of your design. Between the Rosco and GAM libraries, we’ve got over 2,700 patterns to choose from. Any of the steel designs can be affordably made into moving-light sized glass patterns and the range also includes Rotation Gobos and Colorwaves – both of which were created to be installed into automated fixtures that could rotate and change the focus of the pattern. This Spectrum post focuses on how Declan Randall not only used different gobos in his recent design for “Starlight Express,” but also custom glass gobos to project scenic elements onto the stage.

Using Rosco custom gobos for “Starlight Express”By Declan Randall
As a lighting designer, texture in light is extremely important to me. In fact, I think I would really struggle to light without gobos and textured light. Gobos, to me, are so much more than simple projected images. Gobos can tell a story, they can support the artistic intent of the performance and they can add layer upon layer of softly textured and coloured light to any scene.

Designing the lighting for an all-new production of Starlight Express in Johannesburg was a great opportunity to use gobos for both texture and story-telling. The production was staged at the Nelson Mandela Theatre in Johannesburg and was directed by Janice Honeyman with scenic design by James MacNamara. One of the key concepts for me right from the start was to use the lighting to help create a sense of motion on stage – the cast were already on wheels (of course) but we wanted to use the lighting to help create the illusion of speed. One of the ways we did this was through the use of a number of dynamic effects using intensity, colour, movement and most importantly – texture. For anyone who has ever been on a train or who has even watched a train go by, you will have noticed how the light effects caused by the trains movement and light through the windows is almost stroboscopic – several flashes of light and dark. I often used break-ups that offered but chunks of light and shadow so that as the cast skated around it would enhance the illusion of motion as they “flashed” in and out of the light. It was important to use gobos that were geometric and symmetrical as we needed the rhythms created to be consistent and repetitive.

We also used gobos to pick up on textures that were reflected in the scenery – for Dinah’s song “U.N.C.O.U.P.L.E.D.” I picked a pattern that mimicked the panels on the flown archway that way used in the number. The “station yard” scenes between musical numbers was also quite heavily textured – we wanted to create an industrial feel and as the stage floor was painted in varying railroad textures, we helped to enhance this feel by layering both soft-edged and hard-edged gobo washes. Simple shifts in focus could quickly change the feel of the space as the story progressed.

The races are a big part of the show – the trains have to race against each other in a series of heats to find the overall winner. Each race is bigger and more spectacular than the last. Right from the first time I saw the set design I knew that I was going to want to create train tracks out of light. These we would use for the races to add a bit of extra sparkle to the race tracks. To this end, I designed a pair of “train track” gobos – one curved and one straight – and we would use these in different configurations to build the race courses that the trains would follow for each race. We had great fun coming up with different ways to “assemble” the tracks for each race. There is also a big crash just at the start of Race Three and the sections of track went flying out into the auditorium.

Rosco made and supplied the custom train track gobos for the show and they worked really well. We used them in Philips Vari-Lite VL3500 spots and they were a real feature and talking point of the show. The precision of the artwork was critical for the effect to work – there were three trains in each race, each in their own track which was only 800mm wide, so by the time you scale that down to a gobo less than 35mm in diameter, it makes for a super tiny and precise etching of the glass.

The title song of the show (“Starlight Express”) is also used three times during the performance, each one growing and becoming more spectacular, both musically and lighting-wise. For these moments, we wanted to transport Rusty (and by the last refrain, the audience) into a magical world of star light. Night-Sky gobos and another custom star field gobos were used extensively for this effect and were added in layer by layer from both the generic profiles as well as our large moving light rig.

The gobos were a huge part of my design for the show and I cannot imagine having to light the show without them. Tunnels, train tracks, art-deco break-ups, and starry starry nights – textures and images that would not have been possible without Rosco gobos.

When Rosco & GAM merged this spring, there was an outpouring of support from customers expressing their love for their favorite GAM products.  In this Spectrum post we’re going to highlight some of the items that are especially exciting additions to Rosco’s portfolio of products.

GAM Gobos

The Great American Market opened in 1975 selling The Great American Pattern, a range of off-the-shelf stainless steel gobos.  Over the years, GAM has continued to add beautiful, creative and useful patterns – many of which are still among the most popular gobo designs used today.  Soon their “Shadowplay” catalog became a necessity for lighting designers around the world.  Today, the combined libraries of Rosco and GAM standard gobos – including more than 150 new Rosco designs added earlier this year – contain more than 2500 designs to choose from.  Even better for you, Rosco and GAM gobos are manufactured in the same facilities and are shipped from the same warehouses, making it easy to get the GAM Gobo you need: in any size, glass or steel – anywhere in the world.

GAM TwinSpin

Throughout the years, it was common to hear a customer ask for “Rosco TwinSpins.”  Within Rosco’s offices, that request was always a bit awkward since we’d much rather have a designer ask for a DHA Rotator, or Vortex 360.  But now that the GAM TwinSpin has joined our existing “fleet,” we appreciate what a great brand the TwinSpin is and are pleased to add it to our gobo rotator offerings.  With the wide range of features available from the many rotator styles available, you can create virtually any gobo effect on any size budget.  If you need an affordable gobo turning effect, choose the Simple Spin, Vortex 360 or TwinSpin. If you need more control to create more complex effects, choose the Revo , RevoPRO or an Indexing TwinSpin.  No matter which rotator you choose, the answer to the customers’ request for a Rosco TwinSpin is now quite simple – “Sure, how many do you need?”

GAM BlackWrap

Another GAM product we’re excited to offer through Rosco is GAM BlackWrap.  If the TwinSpin is the “Xerox®” to gobo rotators, then BlackWrap is the “Kleenex®” to matte black foil used to shape and block light.  For years, Rosco’s Cinefoil product was known on film sets as “BlackWrap in the blue box.”  So, it’s understandable that one of the most frequently asked questions we’ve gotten since the merger is: “Are you guys keeping BlackWrap or Cinefoil?”  The answer, for now, is both.  Despite the fact that the products perform equally well, some customers prefer Cinefoil and some prefer Blackwrap.  So for the foreseeable future, we plan on making both brands available so that our customers can get exactly the product they prefer to use on their projects.

BlackWrap also adds another Technical Emmy Award™ winning product to our shelves.  For those of you keeping count, this brings Rosco’s tally of prestigious industry awards to 6!  Four Sci-Tech Academy Awards™ and two Technical Emmies.

Innovative GAM Production Tools

One of the reasons the merger between Rosco and GAM makes so much sense is that both companies have a legacy of creating clever, simple, elegant solutions to solve technical problems on set.  GAM products like the GamChek – an electrical testing tool that no TD or electrician should be without, the GAM Stik-up – a great way to add a little light backstage or into an orchestra pit, and WindowGrip – an inventive way to adhere color filters like CTO, Neutral Density, or UV Filter to windows, are three of GAM’s most innovative solutions that are now available wherever Rosco products are sold.

We truly do appreciate all the positive feedback we’ve received since the March announcement about GAM joining Rosco.  It was a great business decision and we’re very happy with the results.  But the real winner in this merger has been you, the end-user.  All of these great GAM products are now available to you through Rosco’s worldwide dealer network. So no matter what your favorite GAM Product is, it’s easier than ever before to get it into your hands, and onto your set, anywhere on the planet.
