Kaip diafragmos nustatymas, užrakto greitis ir ISO jautrumas kontroliuoja ekspoziciją

Diafragmos nustatymas, užrakto greitis ir ISO jautrumas yra glaudžiai susiję fotografuojant. Diafragmos nustatymas valdo atidarymą, kuris reguliuoja į fotoaparatą patenkančios šviesos kiekį, o užrakto greičiu nustatoma, kiek laiko leidžiama šviesai patekti į fotoaparatą. ISO jautrumas nurodo, kokiu greičiu juostelė reaguoja į šviesą. Šie trys aspektai kartu

Rezultatai

Užrakto

Greitas = mažiau šviesos

greitis

Lėtas = daugiau šviesos

vadinami ekspozicijos trikampiu.

Pakeitus užrakto greitį, diafragmos vertę arba ISO jautrumą, galima šį pakeitimą kompensuoti keičiant kitus du aspektus ir išlaikant tą patį patenkančios šviesos kiekį. Tačiau, priklausomai nuo nustatymų, rezultatai bus skirtingi. Pavyzdžiui, užrakto greičiu patartina naudotis norint išreikšti judesį, diafragma naudinga valdant lauko gylį, o ISO jautrumas – valdant nuotraukos grūdėtumą.

Diafragmos

Plati diafragma

= daugiau šviesos

vertė

Siaura diafragma

 

= mažiau šviesos

Plati = mažas lauko gylis

Siaura = didelis lauko gylis

ISO jautrumas

Greitas = kontūrai ryškūs

Lėtas = kontūrai susilieję

Didelis jautrumas

= labiau jautrus šviesai Mažas jautrumas

= mažiau jautrus šviesai

Didelis = didesnis grūdėtumas

Mažas = mažesnis grūdėtumas
