Leti adds a splash of color to stage lighting
What good is it to have 40-LED stage lights that only let you program five colors? That’s exactly the problem that Pascal and Aurélie Baltazar (who won the 2010 Atelier Art-Sciences Arts Award) set out to solve. They wanted to put together a performance where light would play a starring role. Leti helped them out, asking a team of researchers to analyze each LED’s spectrum and flow in order to calculate the dosages required to paint the entire stage with colored light. The researchers even developed special software that lets users control colors with a simple stylus.
The application, used to control stage lighting in real time, can be integrated into stage management software. It can also be used to correct white light, making it warmer or cooler. The system was tested at a performance at the Hexagone theater in Meylan, just outside of Grenoble. The performers gave it a standing ovation!
