Blænder

Blænden er en af de tre faktorer, der bestemmer eksponeringen. Blænderens hus indeholder tynde metalplader, der åbner og lukker for at lade lyset komme gennem blænderen og ind i kameraet. Blændens størrelse er relateret til mængden af lys: En større blænde tillader mere lys, og en mindre blænde tillader mindre lys.

Blændens størrelse angives som en værdi, der kaldes et "F-nummer". F-værdien angiver brændvidden divideret med objektivets diameter. Hvis f.eks. et objektiv med en brændvidde på 50 mm har en f-værdi på F2, er blænderens diameter 25 mm (50 mm/25 mm = F2). Jo mindre tallet er, jo større er blænderens åbning.

Størrelsen på blændeåbningen defineres som eksponeringsværdien (EV). Hvis man øger eksponeringsværdien (+1 EV), betyder dette, at mængden af lys fordobles. Hvis eksponeringsværdien reduceres (-1 EV), halveres lysmængden. Du kan også bruge funktionen for eksponeringskompensationen til at finjustere mængden af lys ved at dele eksponeringsværdierne op i 1/2, 1/3 EV osv.
