Latitude/Profondeur de champ

Recommended Posts

Bonsoir, je ne comprends par pourquoi sachant que :

Image au PR de l’oeil : O777A7(PR) = −f * = −2cm
Image au PP de l’oeil : O777A7(PP) = −1.84 cm
→ Latitude de mise au point = 1.6 mm

 

Alors que la latitude de mise au point correspond à un intervalle et la profondeur de champ = OF - OAPP

Est-ce la même chose ?
