ETC – FOS/4 FRESNEL

N.C

fos/4 reprend les caractéristiques les plus recherchées d’un Fresnel à incandescence standard et y ajoute la multichromie nuancée, les fondus fluides et la technologie LED des autres projecteurs de qualité professionnelle ETC.

Le moment est venu d’offrir à vos spectateurs les tons de peau et les environnements les plus réalistes possible. Pourquoi corriger en postproduction ce que vous pouvez réaliser lors de la production ? fos/4 est disponible en dalle à lumière blanche Daylight HDR variable et en dalle à spectre de couleur complet Lustr X8.

IU intuitive

L’interface utilisateur a été conçue en ayant à l’esprit le processus du travail cinématographique. Les caractéristiques sont simples et intuitives sans faire de compromis sur l’efficacité. Les quatre encodeurs rétroéclairés changent de couleur afin de correspondre aux attributs qu’ils commandent à l’écran.

Même les utilisateurs peu expérimentés peuvent régler les paramètres de manière rapide et précise.

Commande de couleur

Avec fos/4, vous avez la possibilité de changer le mode adopté par défaut des projecteurs. Lorsque l’on travaille avec une synthèse additive des couleurs, le projecteur décide souvent comment mélanger la couleur demandée. Il y a beaucoup d’options. Généralement, les projecteurs choisissent de mélanger la version la plus lumineuse de la couleur que vous essayez de créer. Bien que cela vous donne de l’intensité, cela ne vous procure pas un éclairage de qualité. Viser la qualité peut être synonyme de baisse significative de l’intensité. Nous vous laissons désormais décider de ce que vous voulez voir. Utilisez la fonctionnalité Tune pour choisir le mode le plus lumineux ou à meilleure résolution spectrale.

Zoom 13-55 degrés

Véritable Fresnel avec capacités LED, le Fresnel fos/4 dispose d’une commande de zoom depuis l’avant ou l’arrière du projecteur. Ajustez le faisceau puis utilisez des volets coupe-flux ou d’autres accessoires pour définir les bords.

Rouge intense

En ajoutant une LED rouge intense, nous obtenons un meilleur rendu des tons de peau, des couchers de soleil et des scènes sombres saturées. Nous nous sommes aventurés plus loin dans l’espace chromatique CIE afin de saisir le rouge le plus profond — un rouge qui est essentiel pour rendre avec précision la lueur chaude du feu, l’ambiance romantique d’un coucher de soleil, les tons de peau les plus nuancés et les blancs les plus réels.

L’exacte couleur nuancée de la réalité à la caméra, puis à l’écran. Découvrez comment fos/4 transforme votre façon de travailler au quotidien.
