EV-kompensering

Med denne funktion kan du hurtigt justere den eksponeringsværdi, kameraet har målt, i begrænsede trin, for at forbedre eksponeringen af dine billeder. Indstil EV-kompenseringen til -1,0 EV for at gøre værdien et trin mørkere og 1,0 EV for et trin lysere.

Exif (Exchangeable Image File Format)

En specifikation der definerer et billedfilformat til digitale kameraer, skabt af The Japan Electronic Industries Development Association (JEIDA).

Eksponering

Den mængde lys, der når frem til kameraets sensor. Eksponering styres med en kombination af lukkerhastigheden, blændeværdien og ISO-følsomheden.

Blitz

Et særligt lys, der hjælper dig med at få passende eksponering under ringe lysforhold.

Brændvidde

Afstanden fra midten af objektivet til dets fokuspunkt (i millimeter). En større brændvidde resulterer i en mere snæver synsvinkel, og motivet bliver forstørret. En mindre brændvidde resulterer i bredere synsvinkler.

Billedsensor

Den fysiske del i et digitalt kamera, der indeholder en billedsensor for hvert pixel i billedet. Hver billedsensor registrerer ved en eksponering styrken af det lys, der slipper gennem. Almindelige sensortyper er CCD (Charge Coupled Device) og CMOS (Complementary Metal Oxide Semiconductor).

ISO-følsomhed

Kameraets følsomhed over for lys, baseret på tilsvarende filmhastighed i et filmkamera. Ved indstilling af højere ISO-følsomheder bruger kameraet en højere lukkerhastighed, der kan reducere slør, der skyldes kamerarystelser og ringe lys. Men billeder optaget med høj følsomhed er mere udsatte for støj.

JPEG (Joint Photographic Experts Group)

En tabsgivende metode til komprimering af digitale billeder. JPEG- billeder komprimeres for at reducere deres samlede filstørrelse med minimal forringelse af billedopløsningen.

LCD (Liquid Crystal Display)

Et visuelt display der ofte anvendes i forbrugerelektronik. Disse skærme kræver en separat bagbelysning, som f.eks. CCFL eller LED, for at gengive farver.

Makro

Med denne funktion kan du optage nærbilleder af meget små genstande. Ved brug af makrofunktionen kan kameraet bevare en skarp fokus på små genstande, næsten i fuld størrelse (1:1).
