Si vos photos de nuit sont granuleuses, vous pouvez améliorer leur netteté à l’aide des paramètres Réduction du bruit et Netteté d’Adobe Lightroom Classic.
Libre à vous d’utiliser l’image fournie ou l’une de vos photos de nuit pour en améliorer la netteté. Accédez au module Développement pour effectuer vos retouches. Cliquez ensuite sur le triangle situé sur le côté gauche de votre écran pour masquer le panneau de gauche et agrandir l’espace de travail. Sachant que nous utiliserons exclusivement les paramètres Réduction du bruit et Netteté, développez le panneau Détail.
Appuyez sur la touche Y de votre clavier pour afficher les vues avant et après retouche. Testez le paramètre Luminance, dont l’effet sur le bruit est le plus perceptible. Faites glisser le curseur correspondant complètement à gauche pour voir la quantité de bruit ajoutée, puis complètement à droite pour observer l’effet d’atténuation.
Un réglage extrême de la luminance n’est pas forcément nécessaire ; si la valeur est trop élevée, vous obtenez un lissage peu naturel, et si elle est trop faible, l’image est encore plus granuleuse. L’idéal se situe généralement entre les deux. Ajustez les curseurs Détail et Contraste pour peaufiner les améliorations apportées à l’aide du réglage de la luminance. Cliquez sur le bouton à bascule en haut du panneau Détail pour afficher la photo avant et après retouche. La capture d’écran ci-dessous montre les réglages de réduction du bruit que nous avons appliqués à cette photo.
Nous allons à présent améliorer la clarté de l’image. Utilisez les paramètres Netteté pour mieux faire ressortir les détails. Pour bien voir où le réglage de la netteté sera appliqué, maintenez la touche Alt (Windows) ou Option (Mac OS) enfoncée pendant que vous ajustez les curseurs.
Notre photo de nuit est maintenant beaucoup plus nette.
Vous pouvez nettoyer rapidement vos photos de nuit sans quitter le panneau Détail.
