Korrelasjon mellom brennvidde, vinkel og perspektiv

Brennvidde, som måles i millimeter, er avstanden mellom midten av objektivet og brennpunktet. Den påvirker vinkelen og perspektivet på bildene. En kort brennvidde gir vidvinkel, som lar deg ta et bredt bilde. En lang brennvidde gir smal vinkel, som lar deg ta telefotobilder.

Feltdybde

Portretter eller stillbilder som i størst grad beundres av mennesker, er bilder der bakgrunnen er ute av fokus slik at motivet ser mer markert ut. Avhengig av de fokuserte områdene, kan et bilde være uklart eller klart. Dette kalles "lav feltdybde" eller "høy feltdybde".

Feltdybden er det fokuserte området rundt motivet. Derfor tilsier en liten feltdybde at det fokuserte området er smalt og en stor feltdybde betyr at det fokuserte området er bredt.

Et bilde med lav feltdybde, som legger vekt på motivet og gjør resten av bildet uklart, kan oppnås ved å ta bildet nært motivet eller velge en lav blenderverdi. Tilsvarende kan et bilde med stor feltdybde, der alle elementene i bildet er i skarpt fokus, oppnås ved å ta bildet i avstand fra motivet eller velge en høy blenderverdi.
