PERCEPTUAL CELLS<\/strong><\/p>\n

La s\u00c3\u00a9rie des \u00ab\u00a0perceptual cells\u00a0\u00bb de James Turrell confronte le visiteur \u00c3\u00a0 un espace immersif lumineux de mani\u00c3\u00a8re \u00c3\u00a0 lui faire perdre la notion de l’espace r\u00c3\u00a9el dans lequel il se trouve confin\u00c3\u00a9, au profit d’un espace per\u00c3\u00a7u comme plus vaste, voire infini. Cette sensation troublante est rendu possible par le traitement de la lumi\u00c3\u00a8re projet\u00c3\u00a9e sur un volume sph\u00c3\u00a9rique ou un d\u00c3\u00b4me, emp\u00c3\u00aachant l’oeil de se fixer sur la surface immacul\u00c3\u00a9e.<\/p>\n

CHANGE IN STATE (1990)<\/strong><\/p>\n

Il me reste un souvenir tr\u00c3\u00a8s vivace de l’exp\u00c3\u00a9rience v\u00c3\u00a9cue \u00c3\u00a0 l\u00e2\u20ac\u2122int\u00c3\u00a9rieur de \u00ab\u00a0Change in State\u00a0\u00bb (1990) une de ces \u00ab\u00a0perceptual cells\u00a0\u00bb, \u00c3\u00a0 la galerie Isy Brachot \u00c3\u00a0 Bruxelles en 1991.<\/p>\n

Il s’agit s’une sorte de cabine d\u00e2\u20ac\u2122isolation, un espace individuel de perception. On y entre et on ferme la porte. La hauteur de la cabine est con\u00c3\u00a7ue pour que le visiteur place sa t\u00c3\u00aate sous un d\u00c3\u00b4me r\u00c3\u00a9tro-\u00c3\u00a9clair\u00c3\u00a9 par une source lumineuse, laiteuse et modulable, plac\u00c3\u00a9e hors-champ \u00e2\u20ac\u201c autour du col de l\u00e2\u20ac\u2122h\u00c3\u00a9misph\u00c3\u00a8re. Trois potentiom\u00c3\u00a8tres permettent de changer l\u00e2\u20ac\u2122intensit\u00c3\u00a9 du bleu ou du rouge, ou l\u00e2\u20ac\u2122intensit\u00c3\u00a9 globale, d\u00e2\u20ac\u2122une lumi\u00c3\u00a8re vive jusqu\u00e2\u20ac\u2122\u00c3\u00a0 l\u00e2\u20ac\u2122obscurit\u00c3\u00a9. <\/p>\n

En regardant en l\u00e2\u20ac\u2122air, notre vision se perd dans un simili-infini, un ciel blanc, plomb\u00c3\u00a9, sans le moindre rep\u00c3\u00a8re ni asp\u00c3\u00a9rit\u00c3\u00a9. Toute perception de la distance s\u00e2\u20ac\u2122en trouve compl\u00c3\u00a8tement alt\u00c3\u00a9r\u00c3\u00a9e. La surface parfaitement lisse du d\u00c3\u00b4me semble dispara\u00c3\u00aetre, au profit d\u00e2\u20ac\u2122un espace jug\u00c3\u00a9 \u00c3\u00a9norme. <\/p>\n

L\u00e2\u20ac\u2122isolation, notamment acoustique, renforce encore cette distorsion des sens.<\/p>\n

\u00c3\u20ac en juger d’apr\u00c3\u00a8s le site de James Turrell, deux versions l\u00c3\u00a9g\u00c3\u00a8rement diff\u00c3\u00a9rentes semblent exister (\u00ab\u00a0Header<\/a>\u00a0\u00bb et \u00ab\u00a0Change in State<\/a>\u00ab\u00a0), et j’ignore laquelle j’ai finalement test\u00c3\u00a9.<\/p>\n
