EV (Exponeringsvärde)

Alla kombinationer av kamerans slutarhastighet och bländare som resulterar i samma exponering.

EV-kompensation

Den här funktionen gör det möjligt för dig att snabbt justera exponeringsvärdet som uppmäts med kameran, i begränsade steg, för att förbättra exponeringen av dina bilder. Ställ in EVkompensationen till -1.0 EV för att justera värdet ett steg mörkare och 1.0 EV till ett steg ljusare.

Exif (Exchangeable Image File Format)

En specifikation som används för att definiera ett bildfilsformat för digitalkameror som har skapats av Japan Electronic Industries Development Association (JEIDA).

Exponering

Mängden tillåtet ljus som når kamerasensorn. Exponeringen styrs av en kombination av slutarhastigheten, bländarvärdet och ISOkänsligheten.

Blixt

Ett snabbt ljussken som bidrar till att skapa rätt exponering i förhållanden med låg belysning.

Brännvidd

Avståndet från mitten av objektivet till dess fokuspunkt (i millimeter). Längre brännvidder ger smalare synvinkel och motivet förstoras. Kortare brännvidder ger bredare synvinkel.

Histogram

En grafisk representation av ljusstyrkan i en bild. Den horisontella axeln representerar ljusstyrkan och den vertikala axeln representerar antalet pixlar. Höga punkter åt vänster (för mörkt) och höger (för ljust) i histogrammet indikerar en bild som har fel

exponering.

Bildsensor

Digitalkamerans fysiska delar som innehåller en bildplats för varje pixel i bilden. Varje fotoplats lagrar ljusstyrkan för ljusmängden som träffar den under en exponering. Vanliga sensortyper är CCD (Charge-coupled Device) och CMOS (Complementary Metal Oxide Semiconductor).
