Datavisualization.ch Selected Tools Ufraw Que serait le numérique sans le format raw ? Ce véritable négatif numérique offre d'énormes possibilités et permet de reprendre à posteriori une nouvelle photo. Ses avantages sont nombreux : souplesse de correction de la prise de vue, obtenir l'entière plage dynamique du capteur et ainsi pousser la qualité des retouches photographiques, maintien plus facile de la chaine colorimétrique . . . Ufraw est un logiciel libre permettant de dérawtiser ce format et ainsi d'en obtenir le meilleur possible. Ufraw est une interface graphique de dcraw, ce moteur de dérawtisation libre se retrouve dans bons nombres de logiciels de dérawtisation libres et commerciaux : Adobe Photoshop, ACDSee, IrfanView, Picasa, RawShooter, Raw Convert, etc . . . De ce fait, Ufraw reconnait de nombreux formats (liste des appareils supportés). Il existe plusieurs façons d'utiliser Ufraw, mais à mon sens, la plus facile reste celle utilisée avec Gimp. Gimp est multi-plateforme, et Ufraw s'utilise comme un greffon de Gimp.
