Sistema di misurazione a matrice

Vignettatura

Un sistema avanzato di misurazione dell'esposizione che utilizza un sensore multisegmento e un computer.

Esposimetro a matrice di colori 3D: con un mirino multimetro DP-30 standard o modificato e obiettivi AF NIKKOR di tipo D, l'esposimetro a matrice di colori 3D è attivato automaticamente con il modello F5.

Con le classiche tecniche di valutazione del 18% di riflessione, per determinare l'esposizione vengono utilizzati principalmente fattori quali la luminosità e il contrasto. Per ottenere un'esposizione ottimale è inoltre fondamentale valutare i fattori estetici di ciascuna scena (ad esempio, le ombre di una costruzione, l'effetto blu a temperature basse,

un panorama con un cielo sereno o una scena invernale con la neve). Il misuratore a matrice di colori 3D della fotocamera valuta non solo la luminosità e il contrasto di ogni scena ma anche i colori, mediante uno speciale sensore RGB (Red-Green-Blue). Il potente microcomputer e il database di cui dispone, infine, permettono un controllo dell'esposizione senza precedenti.
