Fonctions de prise de vue > Mesure de l’exposition

Centrée

Le mode Centrée effectue des calculs sur une zone plus large qu’en mode Sélective. Il détermine la quantité de lumière dans la partie centrale de la photo (60 – 80%) ainsi que sur le reste de la photo (20 – 40%). Ce mode est recommandé dans les cas où la différence de luminosité entre un sujet et un arrière-plan est faible, ou qu’une partie du sujet est grande au regard de la composition générale de la photo.

Sélective

La mesure Sélective calcule la quantité de lumière au centre. Lorsque vous réalisez une prise de vue dans des conditions de fort contre-jour derrière un sujet, l’appareil photo règle l’exposition afin de capturer correctement ce dernier. Par exemple, lorsque vous sélectionnez le mode Multiple dans des conditions de fort contre-jour, l’appareil photo considère que la quantité globale de lumière est élevée, ce qui assombrit la photo. Le mode Sélective permet d’éviter cette situation, car la quantité de lumière est calculée dans une zone définie.

Le sujet est clair alors que l’arrière plan est sombre. Le mode Sélective est recommandé dans un cas comme celui-ci, qui présente une différence d’exposition importante entre un sujet et un arrière-plan.
