Merci à tous pour vos réponses
Merci aussi de m'avoir déjà rassuré sur la qualité qu'il est effectivement possible d'obtenir avec cet appareil, notamment pour preuve avec la base de données que Pierre nous indique.
Persuadé qu'il n'existe que 3 possibilités;
1) j'ai tout à apprendre de la pratique de la photo
2) Mon appareil à un souci technique
3) une combinaison des deux point ci-dessus
Je n'espère pas photographier des oiseaux en vol, j'aimerais juste avoir des images les plus nettes possibles d'oiseaux au sol ou sur l'eau...
Je n'ai pas pu déposer une image originale car elle fait approximativement 7Mb et le forum me limite à 2Mb. Elle est redimensionnée avec Gimp à 50%.
J'ai choisi une de mes photos la plus réussie, la majorité des autres sont largement pires, surtout en zoom important, mais à l'affichage à 100% de l'image sur un PC, les Foulques sont flous.
Les métadonnées ci-dessous.
J'espère que cela est utilisable ?
D'avance Merci Merci
