Développez ses fichiers Raw sur le x100s

Posted on Did From Mars !Posted in Technique

Les fichiers images jpg issus du x100s sont réputés de bonne qualité sans aucune intervention nécessaire après la prise de vue. C’est même pour beaucoup d’utilisateurs de Fuji X une (voire LA) raison d’achat. Prendre le parti pris de faire sa prise de vue directement en jpg, c’est l’assurance de passer beaucoup moins de temps sur l’ordinateur en post-traitement. En revanche, cela nécessite de faire un bon nombre de choix à la prise de vue.

Sur la série X de Fuji, les réglages disponibles sur le boitier pour le rendu des jpg sont par exemple :

  • le choix d’une émulation de film (Provia, Astia, Velvia, Pro NEg..NB avec ou sans filtre…)
  • le choix du rendu des hautes lumières
  • le choix du rendu des ombres
  • le Dynamic Range (DR) à 100, 200 ou 400%
  • la saturation des couleurs
  • le niveau d’accentuation des détails
  • le niveau de réduction du bruit

J’en oublie sans aucun doute… mais rien que ceux-ci permettent des centaines de possibilités et il vous restera encore à choisir la sensibilité iso, le diaph, la vitesse…

Donc le jpg direct c’est bien pour économiser du temps APRÈS la prise de vue, mais avant… cela nécessite un peu de temps… :-/

 

Une solution intermédiaire entre « jpg direct » et « traitement des RAW sur ordinateur » existe (et fonctionne super bien chez Fuji) :

prendre ses photos en RAW et les développer sur votre boitier. Cela permet de gagner du temps à la prise de vue et de bénéficier du savoir faire Fuji pour convertir les Raw en JPG. Accessoirement, en faisant ça, vous pourrez comparez les images jpg issues d’un même fichier RAF (le format raw de Fuji) et, ultérieurement, ce processus vous permettra de mieux connaitre votre appareil et par là même de mieux choisir les paramètres qui vous conviennent.
