Lasers are now being used for the first time as a light source for classic motion-picture lighting techniques. The development of larger lighting units is s till limited by the low cost-benefit ratio in the area of scaling performance and color quality. At its world premiere in New York in 1960, the laser was suspiciously regarded as a “ray gun”. Since then, laser technology found applications in medicine, meteorology, and industrial manufacturing, as well as in communications and consumer electronics. In cinemas, laser projection has revolutionized screening quality with razor-sharp images. In automobiles, laser diode headlights provide extremely high luminance density and scope. Lasers also introduce enormous new potential when applied to classic film lighting techniques.
As the first manufacturer of automated professional lighting equipment for the entertainment industry, the Italian company Claypaky launched a moving light equipped with a 180W laser engine that utilizes red, green, and blue banks of lasers. The Xtylos is a compact-beam moving light that uses three lasers for its light source. A sophisticated optical system bundles the three basic colors, so that they emerge as a consistent beam of light.
“The optical system makes it possible to modulate the beam’s exit angle, color mix, and use of gobos”, says Claas Ernst, Managing Director of VisionTwo, the German distribution and service partner of Claypaky. Currently available technology enables the construction of a laser beam and spot variants, which come in a more compact case than their LED-based counterparts.
During the development stage of the laser engine, Claypaky benefited from its parent company Osram, which already had experience with laser-based lighting systems. The compact-beam light, which intensifies colors by using color change and electronic dimming, created a dynamic futuristic stage show for the American hard-rock band Kiss during its performance at Hellfest, the world’s largest heavy metal festival.
By now, Claypaky is part of the ARRI group, and with Skylos it releases a laser-based white light that can be used anywhere as a moving head. Thanks to the efficiency of the 300 W white laser engine, the Skylos can compete in light output with classic Xenon-based search lights of up to 4 kW. This laser-based light outperforms Xenon in energy efficiency by a coefficient greater than ten, just as it outperforms LED luminants by a wide margin.
“The laser engine is designed so that the beam is diffused by different lenses and mirrors”, explains the lighting expert. The construction of wide-area dispersing lights, such as fresnels or floods, is still limited by a low cost-benefit ratio in the area of scaling performance and color quality. “Just as LED lighting technology, which was launched twenty years ago, has since made great technological advances”, emphasizes Claas Ernst, “we can assume that laser technology will eventually overcome its current problems and limitations."
“The time for half-measures and climate denial is over. Unless we move quickly away from fossil fuels, we’re going to destroy the air we breathe, the water we drink, the health of our children, grandchildren and future generations. If we’re going to avoid the worst of the impacts, then we’ve just got to act boldly. And we must act immediately."

"The media has a powerful role to play in the fight against climate change. Through films, television, and all media outlets, we must continue to deliver the message that solutions are out there and are happening now. We have to make it attractive for people to take action. Movies like Avatar, The Day After Tomorrow, and documentaries like Years of Living Dangerously, which I was proud to be a part of, have been very popular, reaching and inspiring millions of people. And I believe films in particular can really inspire and make people want to take action. It’s great to see some of my film-industry friends working with climate related organizations to push forward those messages."
„It‘s high time to reorganize film production in Germany in a ‚greener‘ and more sustainable way. So far, I am flabbergasted by how much our industry works in environmentally harmful ways.To this very day, it starts with until today one-sided print-outs of scripts, and then it continues with plastic bottles in production offices and lots of plastic waste with every catered meal, and it doesn‘t stop with the limousines that pull up to a red carpet.
For many years, people have sneered at me when I brought my own cup or I declined to eat cheap meat served on paper or plastic plates with plastic knives and forks. It would be great if the Green Shooting Card could change all that.“
Director (Ben X, Time of My Life)
„It’s absolutely great that filmmakers all over the world are trying to clean up their act, and are trying to film as sustainable as we possibly can. Still, I think we shouldn’t underestimate the incredible power of the moving image to also change the hearts and minds of people.
So, apart from trying to be more environmentally aware in our business, I think the big gain lies in how we might make everyone more environmentally aware. Yes, cinema can change the world.
I think filmmakers should start using the powerful weapon in our hands that is the camera.
Let’s not only try to do ‘less bad’. Let’s try to do right, and help drive the change that we all know needs to arrive.“
“We are living in a time in which we can’t afford to behave irresponsibly towards nature. The more important is it that film productions try to work as environmentally friendly as possible. A film team produces every day tons of garbage. I try to avoid using plastic cups on set, I bring my own cup, use ecofriendly cosmetics and avoid needless single rides.”

“When we did Noah we knew we were making a film about the first steward of the earth, so we wanted to be good stewards ourselves. There’s so much waste on film sets. Because of groups like Earth Angel, we were able to change that a little bit.”
"As a TV and film producer I try to incorporate environmental storylines into my projects as much as possible. But it’s just as important, if not more, to ‚go green‘ behind the scenes! Therefore, I help run the Producers Guild of America’s Green Initiative.
We provide resources such as a Best Practices and a Carbon Calculator to help producers green their productions. We also partnered with all the major studios to create www.greenproductionguide.com which is a free green vendor database with over 2,000 vendors offering sustainable production solutions worldwide!"
‚Green screens excepted, we will do everything in our power to be as innovative as we can in order to make our production as green as possible.‘

‘It is somewhat embarrassing that green filming is only now becoming an issue in our industry because there have long since been many possibilities to shoot more efficiently.
Technical innovations such as energy efficient lighting are as much a part of this as the awareness of every crew member.’
I do work with a company in the States called Sungevity that leases solar panels to homes. They figured out how to move forward environmentally and how to make it economically successful.
So that’s my small but steadfast global contribution. I think everybody doing a little bit is all that’s made any difference, ever.‘

"Trumbull Studios in Massachusetts is dedicated to being green as much as possible, including the use of LED lighting, solar power, and solar laptops. This is not just because our location has limited amperage and no three-phase, we believe we have a responsibility to our community and our planet to be a clean industry.
We are planning for digital photography in 3D 4K at 120 frames per second from remote and inaccessible locations that will not have available power. Solar is the way to go."
Dieter Kosslick, Director Berlin International Film Festival
„The Berlinale is already actively addressing the sustainability subject since years. We appreciate it very much that a growing number of filmmakers, among them this year‘s jury presiden Darren Aranofsky, is following green guidelines on set.“
Benoit Delhomme
Director of Photography (A Most Wanted Man)
‘I never have been told precisely what the rules are for shooting a green movie, but we are trying to do it. This is something new for me. Sometimes people overlight scenes at night. I don’t. If I can see with my own eyes, then it is enough for the film. In that sense I am a green DoP.’
Academy Award winner Jeremy Irons who stars in the Berlinale Competition entry The Night Train To Lisbon is a fan of source segregated recycling. „Especially in Germany you have done a lot for that. You are examplary in the matter of waste separation.“
The Hollywood actor travelled around the world to promote the environmntal documentary feature film Trashed by Candida Brady which deals with the global garbage problem: „We buy it, we bury it, we burn it and then we ignore it“, says Brady. „With Jeremy Irons as our guide, we discover what happens to the billion or so tons of waste that goes unaccounted for each year.“
Since the world premiere at the International Cannes Film Festival in 2012 Trashed picked up various nominations and awards at international festivals.
