Exposition Animaux Fantastiques @ Musée du Louvre-Lens

Animaux Fantastiques

27 septembre 2023 - 15 janvier 2024

Dragons, griffons, sphinx, licornes, phénix… Présents depuis l’Antiquité, les animaux fantastiques peuplent les moindres recoins de notre monde contemporain, des films et dessins animés aux objets du quotidien. Tour à tour images de terreur ou d’admiration, expression de notre inconscient camouflé ou de nos angoisses, ces créatures souvent hybrides portent en elles une ambiguïté fondamentale. Qui sont-elles ? D’où viennent-elles ? Que signifient-elles ?

Elles partagent avec la faune réelle un pouvoir de fascination sur l’être humain. On leur confère une proximité avec la nature, une sauvagerie mêlée de sagesse. Ce ne sont pas pour autant des animaux comme les autres. Ils s’en distinguent par leur apparence. Gigantesque, démesuré, difforme, leur corps adopte les caractéristiques de plusieurs animaux : corps de cheval et ailes d’oiseaux, aigle à tête de lion…

Cette physionomie extraordinaire reflète des pouvoirs surnaturels. Les animaux fantastiques incarnent les forces élémentaires de la nature : eaux tempétueuses, rafales colériques, mais aussi ruisseaux tranquilles, terre nourricière. Ils représentent leur immensité, leur violence, leur beauté et leurs éclats. Certains possèdent un visage, des mains ou des jambes, qui les rattachent au monde des humains tout en évoquant distance et dangerosité.

Riche de près de 250 oeuvres – sculpture, peinture, objets d’art mais aussi cinéma et musique –, de l’Antiquité à nos jours, l’exposition propose un voyage à travers le temps et l’espace pour raconter l’histoire des plus célèbres de ces animaux à travers leurs légendes, leurs pouvoirs et leur habitat. Elle questionne nos rapports passionnés à ces êtres dont la présence irréelle semble plus que jamais nécessaire.

Le parcours explore, de façon thématique, les différentes facettes de nos rapports aux créatures fantastiques. L’exposition démarre par un retour aux origines de ces animaux imaginaires, qui émergent dès la Préhistoire et incarnent les terreurs sacrées des humains face au vertige de la nature. Dès l’Antiquité, ils sont au coeur de combats fondateurs qui représentent, sous différentes formes, la lutte de forces opposées, notamment celles du bien contre le mal. Outre leur apparence étrange et souvent hybride, les animaux fantastiques ont souvent pour caractéristique principale d’être magiques : ils protègent les peuples et souverains, et veillent sur la frontière entre le monde des vivants et celui des morts. Le dragon occupe une place à part dans cet écosystème : son apparence fluctue selon les siècles et les civilisations, avant d’être progressivement codifiée dans l’art européen puis dans les arts visuels de la culture populaire. Vivant aux marges du réel, les animaux fantastiques contribuent également à incarner une autre forme de société possible. Imprégnant aujourd’hui plus que jamais la pop culture et la fantasy, ces monstres de la nuit des temps nous interrogent quant à nos peurs et nos aspirations, et un besoin de ré-enchantement du monde.

The "Moon lens" ZEISS Biogon 5.6/60: A camera lens custom-made for the Moon

Even though 50 years have passed since the first Moon landing on 20 July 1969, the images have lost none of their fascination. The main reason this event become so firmly entrenched in our collective memory is that it gave us the iconic images captured during the Apollo missions. These were not only the first photographs ever taken of the Moon’s surface – the image of the Earth as seen from the Moon also continues to inspire people of all generations to this day. And all these missions used cameras with lenses developed by ZEISS.

The first Moon landing was also the first global media event. According to media reports, audience ratings amounted to 50 per cent throughout the world, which means that more than 500 million people followed the event live on television. Many of them still know exactly where they were when the Moon landing took place. Newspapers and magazines published special issues that often featured the first color images these publications ever printed. Together with the first stills of the footage shot on the Moon, these photographs are highly coveted collectibles today, among connoisseurs and ordinary people alike.

The history of photography in space took off with the Mercury (1962) and Gemini (1964) program that preceded the Apollo missions. Increasingly, camera lenses were used in the Earth’s orbit. During these years, the ZEISS laboratories further refined their technology and designed camera lenses ready to meet the challenges posed by space.

In October 1968, ZEISS received the order for a camera lens to be used during the Moon landing, which was scheduled to take place a mere nine months later as part of the Apollo 11 mission. “The time for development was extremely brief,” says Dr. Vladan Blahnik who works in research and development at ZEISS. The optical data for the preceding model the ZEISS Biogon 4.5/38 still had to be calculated manually, an extremely time-consuming process. However, a mainframe computer helped to determine the mathematical parameters for the ZEISS Biogon 5.6/60, the camera lens designed for the Moon landing, in a mere couple of weeks. Dr. Erhard Glatzel (1925-2002), a leading mathematician from the optical design department at ZEISS, received the Apollo Achievement Award for this and the development of other special camera lenses for space photography.

The customized ZEISS Biogon 5.6/60 “Moon lens” had to meet a number of requirements. While it was supposed to work within an easy-to-use camera, it also had to precisely map the lunar surface around the landing site. “They decided on a camera fitted with a Reseau plate, which created a grid of cross-marks on the images. These made it possible to calculate the distances between individual objects on the Moon,” explains Blahnik. “The special symmetric design of the camera lens provided an excellent correction for distortions and all other image errors.” A straight line remains a straight line. The images have great definition and edge-to-edge contrast.

Apart from the ZEISS Biogon used on the surface of the Moon, ZEISS designed a number of other special camera lenses for space photography in the 1960s, among them lenses that could transmit UV-waves or extremely fast lenses such as the ZEISS Planar 0.7/50. The engineers at ZEISS continue to benefit from this research until the present day. Some examples are the development of fast lenses for professional movie cameras, lenses for aerial photography used in surveying the Earth’s surface and lithographic lenses employed in the production of microchips.

The camera lens was a small but significant contribution to the Apollo 11 lunar mission. And, incidentally, the cameras with the ZEISS lenses are still up there on the Moon, because on the return journey the astronauts wanted to save every gram in order to take back as many samples of Moon rocks as possible. Only the valuable exposed film made it back to Earth.

Nikon PC-E Nikkor 24mm f/3.5D ED

Wide-angle NIKKOR lens with Perspective Control

Nikon’s high-performance PC (Perspective Control) lens, PC-E NIKKOR 24mm f/3.5D ED, is equipped with a tilt/shift mechanism to give photographers the flexibility to manipulate image perspective, distortion and focus. As both a special-purpose lens and high-performance wide-angle lens, the new PC-E NIKKOR 24mm f/3.5D ED lens represents a significant new addition to the legendary NIKKOR lens family.
The PC-E NIKKOR 24mm makes use of a special mount that enables up to ±11.5mm shift and ±8.5° tilt for perspective control. Shift and tilt are adjusted while referring to the scales provided with gradations at 1mm or 1° intervals. The lens optics can be rotated up to 90° right or left for perspective control adjustment and click-stops are provided every 30°.
The lens aperture can be preset using the aperture ring and the aperture stop-down button. For easy depth-of-field confirmation, it remains stopped down until the button is pressed again. Auto aperture control is also available for SLR models compatible with an electromagnetic diaphragm (Nikon D3 and D300).
In addition to the primary perspective control photographic applications such as architecture and interiors, this lens can also be used for any subject where a 24mm wide-angle lens is appropriate. With a closest focusing distance of only 0.21m and a maximum reproduction ratio of 1/2.7, it is an excellent choice for close-up photography.
Nikon’s original state-of-the-art optical features and technologies are incorporated into the PC-E NIKKOR 24mm for superior picture quality. Nikon’s exclusive Nano Crystal Coat dramatically reduces ghosting and flare caused by internal reflections and three ED glass elements minimize chromatic aberration for higher-resolution, higher-contrast images. Three aspherical lenses effectively correct spherical aberration and coma, while a rounded nine-blade diaphragm opening gives out-of-focus background elements a more natural appearance. The PC-E NIKKOR 24mm offers exceptional optical performance, even at maximum shift settings.
PC-E NIKKOR 24mm f/3.5D ED Features Highlights
  • Wide shifting and tilting range (shift: ±11.5mm; tilt: ±8.5°)
  • ±90° lens revolving capability for versatile tilt/shift effects
  • Maximum reproduction ratio of 1/2.7 (at 0.21m)
  • Three ED-(Extra-low Dispersion) glass elements provide superior sharpness and colour correction by effectively minimizing chromatic aberration
  • Three aspherical lens elements minimize various types of lens aberration
  • Nano Crystal Coat virtually eliminates internal lens element reflections, effectively reducing ghosting and flare
  • High-performance Nikon Super Integrated Coating delivers superior colour reproduction while substantially reducing ghosting and flare
  • Rounded nine-blade diaphragm for more natural appearance of out-of-focus image elements
  • Lens aperture can be preset using an aperture ring and the aperture stop-down button
  • Auto aperture control with electromagnetic diaphragm is possible with the Nikon D3 and D300
