Our technical equipmentEnter the backstage of Chartres en lumières!
With Chartres en lumières, the spectator is invited to wander through the streets of Chartres to discover the city's key sites, illuminated and set to music by numerous scenographers.
But which installations are behind this unique event?
The scenographies of Chartres en lumières propose static or animated creations. Each type of scenography uses different techniques.
The static illuminations
This technique consists in the projection of a glass slide worked with heat (technique used for the work of the stained glass), via an overhead projector. This technique is used for the illuminations of the Eurelium, the quay and the Gloriette wash houses.
The animated scenographies
This technique uses the video mapping technique. Based on the architectural lines of the monuments, the videos unfold a scenario inspired by the monument, its history, its architecture. The animated scenographies are accompanied by a soundtrack. The lamps used operate with xenon or mercury and project HD digital images, stored on server media.
The show of the royal portal of the cathedral benefits from the most innovative technologies of video mapping. The creation benefits from an optimum luminosity and definition thanks to four 4K definition laser projectors of 32,000 lumens.
The annual technical schedule
March: reassembly phase of the structures
This begins with the reassembly of the metal projection towers and the semi-submerged platforms in the Eure and masts, where the projection and lighting equipment rests. In addition, the Chartres en lumières technicians ensure that the electrical connections of each site and the control room connections are working properly.
March to April: adjustment phase
The time for adjustment has arrived. For several weeks, our technicians program the shows and adjust the projection equipment so that the scenographies reveal their beauty to the public. This requires a synchronization between the parameters and the artistic supports. A meticulous work whose reward is to discover in preview the scenographies of Chartres en lumières.
April to October: launch of the event and the Festival of Light
From the beginning to the end of Chartres en lumières, technicians proceed to the daily start-up of the shows and to the follow-up of the quality of the rendering. Preventive and operational maintenance is carried out so that you can enjoy the experience to the fullest: change of artistic supports such as films or slides, for example. In September, it's the Festival of Light that requires all their attention for an evening more festive than ever.
December to January: launch of the Christmas scenographies
The end of year celebrations are an opportunity to propose new decorations on the main monuments: The royal portal of the cathedral, the Fine Arts Museum's facade of honor, the Saint-André collegiate church, the Minimes bridge, the Gloriette quay and wash houses, the Bouju bridge, the Foulerie wash house, the Saint-Hilaire arcades, the Saint-Hilaire bridge, the Grenouillère wash house, the Saint-Père bridge and, for the first time in 2022, the Montescôt Hotel.
January to March: dismantling of structures / maintenance, cleaning, repair and optimization
Chartres en lumières is now over. It is therefore time to dismantle the projection structures at the end of the season. The technical department is finalizing the complete dismantling of each device and is taking care of the projection devices. Change of mechanical parts, greasing, electronic and computer maintenance, refurbishing of the equipment... Nothing is neglected to give you more emotions year after year.
