Façon dont le réglage de l’ouverture, de la vitesse d’obturation et de la sensibilité ISO contrôlent l’exposition

En photographie, les paramètres d’ouverture, de vitesse d’obturation et de sensibilité ISO sont étroitement liés. Les paramètres d’ouverture contrôlent et régulent la quantité de lumière qui pénètre dans l’appareil photo, alors que la vitesse d’obturation détermine la durée au cours de laquelle la lumière peut pénétrer. La sensibilité ISO correspond à la vitesse à laquelle un appareil photo réagit à la lumière. Ensemble, ces trois aspects sont désignés en tant que triangle d’exposition.

Un changement de la vitesse d’obturation, de la valeur d’ouverture ou de la sensibilité ISO peut être compensé par un réglage des autres valeurs pour maintenir la quantité de lumière. Néanmoins, les résultats varient en fonction des paramètres utilisés. Par exemple, la vitesse d’obturation est utile pour capturer des mouvements, l’ouverture permet de contrôler la profondeur de champ et la sensibilité ISO le grain d’une photo.
