Egretta garzetta
Pelecaniformes - Ardeidae
Pour ceux qui connaissent la réserve ornitho, il se passe presque toujours quelque chose au 20 - où l'on peut photographier le Martin pêcheur occasionnellement - mais souvent, aigrettes et Hérons cendrés se tiennent dans la lagune de droite au fond et y prennent leur bain. La distance est grande, très juste avec mon 500 mm pour des photos d'une excellente netteté et je voulais tester le 800 mm sur une telle distance. Le challenge particulier ici était la blancheur du plumage et ajoutait à la difficulté de prendre bien net. J'ai donc carrément sous-exposé à -2, ce qui m'a permis une vitesse supérieure sans augmentation des ISOs, toujours en automatiques et en mode manuel.Voici le résultat:
Testing the 800 mm focus in the distance on white plumage of the Litlle egret
At the Teich bird preserve on the Atlantic coast, most of the time there will be birds at hide 20 - where the kingfisher can be photographed at the right season - and often egrets and Grey herons fly into the most distant lagoon and bathe there. The distance is quite significant - and frustrating! -, and hardly manageable with my 500 mm lens for a decent focus so I wanted to test the 800 mm on such a distance. The particular challenge here was the whiteness of the Egret's plumage which added to the difficulty. Thus, I under-exposed to -2 which allowed me a superior speed without increasing the ISOs, as usual on automatic and in the manual mode.
