Konsepter innen fotografering

Hvordan blenderinnstilling, lukkerhastighet og ISO-følsomhet kontrollerer eksponeringen

Blenderinnstilling, lukkerhastighet og ISO-følsomhet er tett forbundet innen fotografering. Blenderinnstillingen kontrollerer åpningen som regulerer lyset som kommer inn i kameraet, mens lukkerhastigheten bestemmer tidslengden som lys slipper inn. ISO-følsomheten fastslår hastigheten som filmen reagerer på lys med. Sammen blir disse tre aspektene beskrevet som eksponeringstriangelet.

Høy hastighet = mindre lys Lav hastighet = mer lys

Rask = stille

Sakte = uklart

En endring i lukkerhastighet, blenderverdi eller ISO-følsomhet kan utløses av justeringer av de andre faktorene for å opprettholde mengden lys. Resultatene endres imidlertid i henhold til innstillingene. For eksempel er lukkerhastighet nyttig for å uttrykke bevegelse, blenderen kan kontrollere feltdybden, og ISO-følsomheten kan kontrollere hvor kornete et bilde ser ut.
