Blændens betydning

Et objektivs blænde kan justeres for at kontrollere den lysmængde, der når frem til billedsensoren. Det kan forklares med den måde, pupillen i menneskets øje bliver mindre, når den udsættes for skarpt lys.

Næste billede viser, hvordan blænden justeres til en anden værdi i henhold til det tilhørende blændestop, der er beskrevet på objektivet. (Billedet kan være forskelligt

fra produktet og repræsenterer ikke en speciﬁk objektivmodel).

Åbning af blænde (mindre blændeværdi)

Motiver, der er hhv. nærmere og længere væk end objektet i fokus, vil være ude af fokus.

Du kan se, at baggrunden er ude af fokus, når du fokuserer på motivet.

▲ Blænde: f = 2.8, Lukkertid: 1/500sek.

Lukning af blænde (større blændeværdi)

Fokusområdet udvides både foran og bagved motivet.

Du kan se, at både motivet og baggrunden er i fokus, hvis du bruger et højt blænde- stop.

▲ Blænde: f = 11, Lukkertid: 1/500sek.
