Lauko gylis

Labiausiai žmonių vertinamos portretinės ar natiurmortinės nuotraukos yra tokios, kuriose fonas yra nesufokusuotas, taigi objektas atrodo ryškus. Priklausomai nuo sufokusuotų sričių, nuotrauka gali būti susiliejusi arba ryški. Tai vadinama „mažu DOF“ arba „dideliu DOF“.

Lauko gylis yra sufokusuota sritis aplink objektą. Taigi mažas DOF nurodo, kad sufokusuota sritis yra siaura, o didelis DOF reiškia, kad sufokusuota sritis yra plati.

Nuotrauką su mažu DOF, kurioje pabrėžiamas objektas ir visa kita yra neryšku, galima gauti naudojant teleskopinį objektyvą arba pasirenkant mažą diafragmos vertę. Ir atvirkščiai, nuotrauka su dideliu DOF, kurioje visi elementai sufokusuoti aštriai, gali būti gaunama naudojant plačiakampius objektyvus arba pasirenkant didelę diafragmos vertę.

Nuo ko priklauso nesufokusuoto vaizdo efektai?

DOF priklauso nuo diafragmos vertės

Kuo diafragma platesnė (kuo mažesnė diafragmos vertė), tuo DOF mažesnis. Kai kitos vertės, įskaitant užrakto greitį ir ISO jautrumą, yra lygios, maža diafragmos vertė lems nuotrauką su mažu DOF.
