Description
English: A test image to check your monitor's response to photographic shadow detail. The four circles have RGB values 6, 12, 26 and 38 (out of 255). If you see all four, your monitor is set on the bright side. Three is OK, but if you see fewer than three, your display doesn't show shadow detail properly.
Français : Une image de test pour vérifier la réponse de votre moniteur aux détails des ombres photographiques. Les quatre cercles ont les valeurs RVB 6, 12, 26 et 38 (sur 255). Si vous voyez les quatre, votre moniteur est réglé du bon côté. Trois, c'est bien, mais si vous en voyez moins, votre écran n'affiche pas correctement les détails des ombres.
