Fotografēšanās koncepcijas

Asuma dziļums

Parasti fons ir ārpus fokusa, lai objekts izceltos, portretos un klusās dabas fotoattēlos, kas ir iecienītākie cilvēku vidū. Atkarībā no fokusētajiem apgabaliem fotoattēls var tikt izpludināts vai asināts. Tas ir tā saucamais „zemais DOF“ vai „augstais DOF“.

Lauka dziļums ir fokusētais apgabals ap objektu. Tāpēc neliels DOF nozīmē, ka fokusētais apgabals ir šaurs, un liels DOF nozīmē, ka fokusētais apgabals ir plats.

Fotoattēlu ar nelielu DOF, kas izceļ objektu un pārējos elementus izpludina, var izveidot, izmantojot teleskopa objektīvu vai izvēloties zemu diafragmas atvēruma vērtību. Un otrādi - fotoattēlu ar lielu DOF, kas asi rāda visus fotoattēla elementus, var izveidot, izmantojot platleņķa objektīvu vai izvēloties augstu diafragmas atvēruma vērtību.

Kas kontrolē ārpusfokusa efektus?

DOF atkarīgs no diafragmas atvēruma vērtības

Jo platāks diafragmas atvērums (attiecīgi, jo zemāka diafragmas

atvēruma vērtība), jo zemāks ir DOF. Apstākļos, kur pārējās vērtības, tajā skaitā aizvara ātrums un ISO jutība ir vienādas, zema diafragmas atvēruma vērtība veido fotoattēlu ar zemu DOF.
