Diafragma

Diafragma, anga reguliuojant į fotoaparatą patenkančios šviesos kiekį, yra vienas iš trijų elementų, reguliuojančių išlaikymą. Diafragmos angelę dengia plonos, metalinės plokštelės, kurioms atsivėrus šviesa patenka

įfotoaparato vidų. Diafragmos dydis yra labai susijęs su nuotraukos ryškumu: kuo didesnė diafragma, tuo ryškesnė nuotrauka; kuo mažesnė – tuo tamsesnė.

Diafragmos dydį nurodo reikšmė, žinoma kaip„F“ skaičius.„F“ skaičius nurodo fokusuojamą atstumą padalintą iš objektyvo diametro. Pavyzdžiui, jei 50 mm objektyvo fokusuojamo atstumo„F“ skaičius yra F2, diafragmos diametras yra 25 mm. (50 mm/25 mm = F2) Kuo mažesnis„F“ skaičius, tuo didesnė diafragma.

Diafragmos atsivėrimas vadinamas ekspozicijos verte (EV). Padidinus ekspozicijos vertę (+1 EV) gaunamos šviesos kiekis padvigubėja. Sumažinus ekspozicijos vertę (-1 EV) gaunamos šviesos kiekis sumažėja perpus. Galite naudotis ir ekspozicijos kompensavimo funkcija, kad priderintumėte gaunamos šviesos kiekį padalindami ekspozicijos vertes į 1/2, 1/3 EV ir panašiai.
