Vitesse d'obturation

La vitesse d'obturation est définie par la durée nécessaire à l'ouverture et à la fermeture de l'obturateur. Dans le cadre de la luminosité d'une photo, la vitesse d'obturation constitue un facteur important car elle contrôle la quantité de lumière qui passe à travers l'ouverture avant d'atteindre le capteur d'images.

Généralement, la vitesse d'obturation est réglable manuellement. La mesure de la vitesse d'obturation est connue sous le nom de « Valeur d'exposition » (EV), qui se caractérise par des intervalles de 1 s, 1/2 s, 1/4 s, 1/8 s, 1/15 s, 1/1 000 s, 1/2 000 s, et ainsi de suite.

Par conséquent, plus la vitesse d’obturation est élevée, moins la lumière pénètrera et plus la vitesse d’obturation est faible, plus la lumière pénètrera.

Comme présenté sur la photo ci-dessous, une vitesse d'obturation lente laisse plus de temps à la lumière pour pénétrer, la photo devient donc plus claire. Par ailleurs, une vitesse d'obturation rapide accorde moins de temps à la lumière pour pénétrer. La photo devient plus sombre et immobilise un sujet en mouvement plus facilement.
