Français : Illustration de l'évolution de la profondeur de champ en fonction des dimensions de la surface sensible..
Ouverture f/4 ; mise au point à 1,5 m. Référence focale de 50 mm sur surface 24x36 et diamètre du cercle de confusion 50 mm. Pour les autres formats, on conserve le même angle de champ horizontal, les focales sont donc proportionnelles aux largeurs des surfaces photosensibles. Même choix pour les diamètres des cercles de confusion. |
